Bones provide a firm framework that gives shape to the body, supports Its parts, and protects vital organs such as the brain, heart, lungs, etc., from Injury. The bones also facilitate body movement by acting In cooperation with numerous muscles attached to the bones by tendons. Bone growth and development continues from birth to about twenty years of age. Cartilage furnishes elastic, supporting connective tissues which protect the bones at the joints from shock and give the skeleton more flexibility. Infants have approximately three hundred fifty bones, many of which fuse during the process of growth. Adults vary somewhat In the number of bones, but a total of two hundred six bones Is considered normal or typical. The skeletal system consists of two divisions: the axial skeleton and the appendicular skeleton. The axial skeleton, the main framework of the body, consists of the spine, skull, and chest. The appendicular skeleton consists of the bones of the upper and lower extermltles. The skull Is defined as the bony framework of the head. The 29 bones of the skull include those of the cranium and face, the hyoid bone, and the ear osslcles. The 8 cranial bones enclose a cavity within which are the brain, 3 layers of protective membranes (pia mater, arachnoid, and dura mater), and numerous blood vessels. Fourteen Irregular bones, including the lower and upper Jaw bones, nasal bones, and cheek bones, form the bony framework of the face. The human skull, compared with the skulls of other animals, displays a relative decrease In the size of the face and a relative Increase In the size of the cranium. There are actually 5 great cavities of the skull: two cavities, or orbits, enclosing the eyes; the nasal cavity, with Its two chambers separated by the septum; the oral cavity, with the Jaw bones and maxillae, platlne, and sphenoid bones; and the cranial cavity. There are Important cavities, called paranasal sinuses, In the walls of some df the skull bones adjacent to the nasal cavity. These sinuses have a lining of ciliated mucous membrane which is continuous with that of the nasal cavity, and they drain into the nasal passageways and help to moisten them. The paranasal sinuses are useful resonating chambers for the voice, but the continuity of the membrane with that of the nose and mouth permits infectious material to spread rapidly through the various passageways, as in the common coid. The U-shaped bone In the neck, the hyoid bone, is the only bone that does not meet with other bones to form a joint; ligaments connect it with an extension of the temporal bone. Some of the muscles of the tongue and mouth Insert In the hyoid. A word about the quality of our MPL skeletons. These are not models in the usual context of the word since models are first sculpted or carved and then copied. Our skeletons are cast by hand from molds taken from a 5' 2" Human (male) skeleton and thus are not models but authentic anatomical reproductlons--wlth all the advantages of a human skeleton andnoneof thedisadvantages.

  • Module 2 : Anatomy – the Skeleton
    Module 2 : Anatomy – The Skeleton In this module you will learn: The functions of the skeletal system The types of bones in the human body The effects of exercise on your bones What happens to the bones as we get older When studying to become a fitness instructor or personal trainer, you will learn all about the anatomy of the human body. Studying the skeleton is one of the foundations of your trade, you will need to know how the body is structured, the names of each bone, types of bones, importance of bone and joint health, detail of the spine and different terms of movement. Without stating the obvious, each of your clients has their own skeleton and you must be fully aware of how this works. This is for many reasons; you are a teacher and must be fully aware of how to prevent injuries, avoid unnecessary stress on the bones and, if qualified, help the client prevent or heal bone and joint related conditions or medical problems. 2.1 Understanding the Skeletal System The skeleton is comprised of 206 different bones that provide 5 main functions: Support mechanism for muscle and tissue Protection for organs Movement with bones, muscles, and joints Storing minerals and blood cells Growth Skeletal System 2.2 Bones are Formed by Ossification Some bones (such as the flat bones of your skull) in the body are formed in a similar stage to connective tissue. The process is known as direct or intramembranous ossification. Other bones are made up of cartilaginous matter, this is developed from future bone in the embryo which then dissolves and is replaced with other bone cells.

  • The Muscular System
    THE MUSCULAR SYSTEM COMPILED BY HOWIE BAUM 1 Muscles make up the bulk of the body and account for 1/3 of its weight.!! Blood vessels and nerves run to every muscle, helping control and regulate each muscle’s function. The muscular system creates body heat and also moves the: Bones of the Skeletal system Food through Digestive system Blood through the Circulatory system Fluids through the Excretory system MUSCLE TISSUE The body has 3 main types of muscle tissue 1) Skeletal, 2) Smooth, and 3) Cardiac SKELETAL MUSCLE SMOOTH MUSCLE CARDIAC MUSCLE Skeletal muscles attach to and move bones by contracting and relaxing in response to voluntary messages from the nervous system. Skeletal muscle tissue is composed of long cells called muscle fibers that have a striated appearance. Muscle fibers are organized into bundles supplied by blood vessels and innervated by motor neurons. Muscle structure Skeletal (striated or voluntary) muscle consists of densely packed groups of hugely elongated cells known as myofibers. These are grouped into bundles (fascicles). A typical myofiber is 2–3 centimeters ( 3/4–1 1/5 in) long and 0.05millimeters (1/500 inch) in diameter and is composed of narrower structures – myofibrils. These contain thick and thin myofilaments made up mainly of the proteins actin and myosin. Numerous capillaries keep the muscle supplied with the oxygen and glucose needed to fuel contraction. Skeletal Muscles • Skeletal muscles attach to bones by tendons (connective tissue) and enable movement. • Skeletal muscles are mostly voluntary Feel the back of your ankle to feel your Achilles tendon - the largest tendon in your body.

  • Is the Skeleton Male Or Female? the Pelvis Tells the Story
    Activity: Is the Skeleton Male or Female? The pelvis tells the story. Distinct features adapted for childbearing distinguish adult females from males. Other bones and the skull also have features that can indicate sex, though less reliably. In young children, these sex-related features are less obvious and more difficult to interpret. Subtle sex differences are detectable in younger skeletons, but they become more defined following puberty and sexual maturation. What are the differences? Compare the two illustrations below in Figure 1. Female Pelvic Bones Male Pelvic Bones Broader sciatic notch Narrower sciatic notch Raised auricular surface Flat auricular surface Figure 1. Female and male pelvic bones. (Source: Smithsonian Institution, illustrated by Diana Marques) Figure 2. Pelvic bone of the skeleton in the cellar. (Source: Smithsonian Institution) Skull (Cranium and Mandible) Male Skulls Generally larger than female Larger projections behind the Larger brow ridges, with sloping, ears (mastoid processes) less rounded forehead Square chin with a more vertical Greater definition of muscle (acute) angle of the jaw attachment areas on the back of the head Figure 3. Male skulls. (Source: Smithsonian Institution, illustrated by Diana Marques) Female Skulls Smoother bone surfaces where Smaller projections behind the muscles attach ears (mastoid processes) Less pronounced brow ridges, Chin more pointed, with a larger, with more vertical forehead obtuse angle of the jaw Sharp upper margins of the eye orbits Figure 4. Female skulls. (Source: Smithsonian Institution, illustrated by Diana Marques) What Do You Think? Comparing the skull from the cellar in Figure 5 (below) with the illustrated male and female skulls in Figures 3 and 4, write Male or Female to note the sex depicted by each feature.

  • Musculoskeletal Morphing from Human to Mouse
    Procedia IUTAM Procedia IUTAM 00 (2011) 1–9 2011 Symposium on Human Body Dynamics Musculoskeletal Morphing from Human to Mouse Yoshihiko Nakamuraa,∗, Yosuke Ikegamia, Akihiro Yoshimatsua, Ko Ayusawaa, Hirotaka Imagawaa, and Satoshi Ootab aDepartment of Mechano-Informatics, Graduate School of Information and Science and Technology, University of Tokyo, 7-3-1, Hongo, Bunkyo-ku, Tokyo, Japan bBioresource Center, Riken, 3-1-1 Takanodai, Tsukuba-shi, Ibaragi, Japan Abstract The analysis of movement provides various insights of human body such as biomechanical property of muscles, function of neural systems, physiology of sensory-motor system, skills of athletic movements, and more. Biomechan- ical modeling and robotics computation have been integrated to extend the applications of musculoskeletal analysis of human movements. The analysis would also provide valuable means for the other mammalian animals. One of current approaches of post-genomic research focuses to find connections between the phenotype and the genotype. The former means the visible morphological or behavioral expression of an animal, while the latter implies its genetic expression. Knockout mice allows to study the developmental pathway from the genetic disorders to the behavioral disorders. Would musculoskeletal analysis of mice also offer scientific means for such study? This paper reports our recent technological development to build the musculoskeletal model of a laboratory mouse. We propose mapping the musculoskeletal model of human to a laboratory mouse based on the morphological similarity between the two mammals. Although the model will need fine adjustment based on the CT data or else, we can still use the mapped musculoskeletal model as an approximate model of the mouse’s musculoskeletal system.

  • Skeletal System Fact Sheet
    Skeletal system fact sheet • At birth the human skeleton is made up of around 300 bones. By adulthood, some bones have fused together to end up with 206 bones. • Human bones grow continually from birth till our mid 20's. Our skeleton's bone mass is at its maximum density around the age of 30. • If broken our bones will re-grow and repair themselves. Often doctors will place a cast on splint to make sure these bones repair straight and true. • The axial skeleton part of the human skeleton has 80 bones. It includes the vertebral column, the rib cage and the skull and helps us maintain our upright posture, by spreading the weight in the head, and upper areas down to the lower areas near the hips. • The appendicular skeletal section of our skeleton has 126 bones. It includes the pectoral (shoulder) girdles, the pelvic girdle and the bones of the lower and upper limbs. Its function is for movement of the body and to protect some organs. • The human skeletal system has six major functions including the production of blood cells, for support, for movement, for protection, for storage of ions and endocrine regulation. • The longest bone in the human body is the thigh bone called the femur. • The smallest bone found in the human body is located in the middle ear. The staples (or stirrup) bone is only 2.8 millimetres (0.11 inches) long. • Like our skin, the human body's bones are also constantly worn down and re-made, to the point where every 7 years we essentially have a new bone.

  • Coracoid Process Anatomy: a Cadaveric Study of Surgically Relevant Structures Jorge Chahla, M.D., Ph.D., Daniel Cole Marchetti, B.A., Gilbert Moatshe, M.D., Márcio B
    Quantitative Assessment of the Coracoacromial and the Coracoclavicular Ligaments With 3-Dimensional Mapping of the Coracoid Process Anatomy: A Cadaveric Study of Surgically Relevant Structures Jorge Chahla, M.D., Ph.D., Daniel Cole Marchetti, B.A., Gilbert Moatshe, M.D., Márcio B. Ferrari, M.D., George Sanchez, B.S., Alex W. Brady, M.Sc., Jonas Pogorzelski, M.D., M.H.B.A., George F. Lebus, M.D., Peter J. Millett, M.D., M.Sc., Robert F. LaPrade, M.D., Ph.D., and CAPT Matthew T. Provencher, M.D., M.C., U.S.N.R. Purpose: To perform a quantitative anatomic evaluation of the (1) coracoid process, specifically the attachment sites of the conjoint tendon, the pectoralis minor, the coracoacromial ligament (CAL), and the coracoclavicular (CC) ligaments in relation to pertinent osseous and soft tissue landmarks; (2) CC ligaments’ attachments on the clavicle; and (3) CAL attachment on the acromion in relation to surgically relevant anatomic landmarks to assist in planning of the Latarjet procedure, acromioclavicular (AC) joint reconstructions, and CAL resection distances avoiding iatrogenic injury to sur- rounding structures. Methods: Ten nonpaired fresh-frozen human cadaveric shoulders (mean age 52 years, range 33- 64 years) were included in this study. A 3-dimensional coordinate measuring device was used to quantify the location of pertinent bony landmarks and soft tissue attachment areas. The ligament and tendon attachment perimeters and center points on the coracoid, clavicle, and acromion were identified and subsequently dissected off the bone. Coordinates of points along the perimeters of attachment sites were used to calculate areas, whereas coordinates of center points were used to determine distances between surgically relevant attachment sites and pertinent bony landmarks.

However, this age varies with racial, geographic, Galstaun 1937 9; Basu and Basu 1938 3,4 ; Lal and climatic and various other factors. Study of various text books in 12 et al 8 Anatomy and Radiology exhibits a glaring discrepancy as regards Townsend 1939 ; Gupta . 1974 ). Because of the the ages at which the different epiphyses fuse with the respective existence of such racial, geographic and climatic diaphyses in long bones. These variations have suggested need of variations, need for separate standards of ossification for separate standard of ossification for separate regions. This leads us separate regions have been suggested (Loder et al 1993 14 ; to study ages of epiphyseal union around elbow joint, a rarely Koc et al. 2001 10 ; Crowder et al. 2005 6).
