Neurosurgery, Seattle Science Foundation Corresponding author: Erfanul Saker, [email protected] Abstract Few studies have examined the costovertebral joint and its ligaments in detail. Therefore, the following review was performed to better elucidate their anatomy, function and involvement in pathology. Standard search engines were used to find studies concerning the costovertebral joints and ligaments. These often- overlooked ligaments of the body serve important functions in maintaining appropriate alignment between the ribs and spine. With an increasing interest in minimally invasive approaches to the thoracic spine and an improved understanding of the function and innervation of these ligaments, surgeons and clinicians should have a good working knowledge of these structures. Categories: Neurosurgery, Orthopedics, Rheumatology Keywords: costovertebral joint, spine, anatomy, thoracic Introduction And Background The costovertebral joint ligaments are relatively unknown and frequently overlooked anatomical structures [1]. Although small and short in size, they are abundant, comprising 108 costovertebral ligaments in the normal human thoracic spine, and they are essential to its stability and function [2-3].

Netter's Musculoskeletal Flash Cards, 1E
Netter’s Musculoskeletal Flash Cards Jennifer Hart, PA-C, ATC Mark D. Miller, MD University of Virginia This page intentionally left blank Preface In a world dominated by electronics and gadgetry, learning from ﬂ ash cards remains a reassuringly “tried and true” method of building knowledge. They taught us subtraction and multiplication tables when we were young, and here we use them to navigate the basics of musculoskeletal medicine. Netter illustrations are supplemented with clinical, radiographic, and arthroscopic images to review the most common musculoskeletal diseases. These cards provide the user with a steadfast tool for the very best kind of learning—that which is self directed. “Learning is not attained by chance, it must be sought for with ardor and attended to with diligence.” —Abigail Adams (1744–1818) “It’s that moment of dawning comprehension I live for!” —Calvin (Calvin and Hobbes) Jennifer Hart, PA-C, ATC Mark D.

ISSN 2321- 4287 Case Report DOI: 10.16965/ijar.2014.538 MULTIPLE OSSIFIED COSTAL CARTILAGES FOR 1ST RIB Raghavendra D.R. *1, Nirmala D 2. *1 Post graduate student, Department of anatomy, J J M Medical College, Davangere, Karnataka, India. 2 Associate Professor, Department of anatomy, J J M Medical College, Davangere, Karnataka, India. ABSTRACT Costal cartilages are flattened bars of hyaline cartilages. All ribs except the last two, join with the sternum through their respective costal cartilages directly or indirectly. During dissection for 1st MBBS students in the Department of Anatomy, JJMMC, Davangere, variation was found in a male cadaver aged 45 –50 years. Multiple ossified costal cartilages for 1st rib were present on left side. There were 3 costal cartilages connecting 1st rib to manubrium. There were two small intercostal spaces between them. The lower two small costal cartilages fused together to form a common segment which in turn fused with large upper costal cartilage. The large upper costal cartilage forms costochondral joint with 1st rib. All costal cartilages showed features of calcification. The present variation of multiple ossified costal cartilages are due to bifurcation of costal cartilage. It may cause musculoskeletal pain, intercostal nerve entrapment or vascular compression. Awareness of these anomalies are important for radiologists for diagnostic purpose and for surgeons for performing various clinical and surgical procedures. KEYWORDS: Costal cartilage, bifurcation of Rib, Sternum. Address for Correspondence: Dr. Raghavendra D.R.

The M. Transversus Thoracis in Man and Monkey
Okajimas Fol. anat. jap., 48: 103-137, 1971 The M. Transversus Thoracis in Man and Monkey By Jun-ichiro Satoh Department of Anatomy, Faculty of Medicine, Nagasaki University, Nagasaki, Japan Received for publication, December 2, 1970— Of the Mm. thoracis proprii and profundi in man, the muscles that run across the ribs in the most inner layer of the thoracic wall have been termed the Mm. subcostales by Eisler. Of these, the group of muscles located in the mid-anterior chest are the Mm. transversi thoracis while those in the posterior chest are the Mm. subcostales in the narrow sense. The purpose of the present report is to describe the M. transversus thoracis in man and monkey, especially the nerve supply to these muscles which has not yet been documented in detail. The material of study consisted of bodies of adult Japanese (24 cases), Crab-eating monkey (Macaca irus, 15 cases) and Formosan mon- key (Macaca cyclopis, 15 cases). The condition on both sides of the body was examined with magnifying lenses having an illumination attach- ment. Findings I. Mm. transversi thoracis in man In man, the Mm. transversi thoracis were found to be flat, narrow muscles which are multiform being quite variable in shape. In the region of the lateral edge of the sternum, especially at the xiphoid process, they were united each other so that the muscles particularly the lower ones, frequently form so-called muscular digitation, the tip being the attachment to the rib (figures 1 and 2). 1. This muscle arose by tendon from the rib in the area of the costo- chondral joint, that is, from the region extending from the lateral tip of the costal cartilage to the bony rib.

The Vertebral Column Is 33 Vertebrae Held Together by Ligaments and Muscles, with Intervertebral Discs in Between
The vertebral column is 33 vertebrae held together by ligaments and muscles, with intervertebral discs in between. The vertebral column provides support and upright posture (attenuates loads) for the body. It is also a site for many muscle attachments. There are natural curves in the spine to help with the support and posture, as well as increasing the flexibility of the spine. The 33 vertebrae are divided into 5 sections, with each group having unique features designed for specific purposes. The groups are: cervical (7), thoracic (12), lumbar (5), sacrum (5), and coccyx (4). All vertebrae have a body, 2 transverse processes, a spinous process, superior/inferior articulating facets, lamina, pedicle, and a vertebral foramen. 1 There are anterior convex curves in the cervical and lumbar spines. Posterior concave curves occur in the thoracic and sacral-coccygeal spines. The curves of the spine may increase/decrease as the body’s center of gravity shifts (ex: pregnancy, weight gain/loss, trauma)—this is a result of trying to maintain in the upright position, the brain over the body’s center of gravity. 2 Scoliosis—excessive lateral curvature; side to side Kyphosis—hunchback; excessive curvature of thoracic Lordosis—swayback ; excessive curvature of lumbar 3 C1 and C2 are shaped differently than the other 5 cervical vertebrae to permit the head to rotate. C1 (atlas) = holds up the world (head) and is missing a body; it articulates with the occipital bone as well as rotating around the odontoid process (dens) of the C2 vertebrae (atlantoaxial joint). The atlantoaxial joint is what type of joint?? C2 (axis) = odontoid process projects up C3-C7 = the body is small and all the processes are short and blunted.
