Vertebral Column EDU - Module 2 > Thorax & Spine > Thorax & Spine Vertebral column (aka, spinal column, aka, spine) • It encloses and protects the spinal cord. • It provides attachment sites for muscles of the head, neck, and trunk. • The individual vertebrae are named according to their region and vertical order. For example, T1 is the first vertebra of the thoracic region. • The S- shaped curve of the vertebral column facilitate its flexibility and resilience. Regions of the Vertebral Column: Cervical • 7 vertebrae within the neck. • C1 and C2 have unique anatomical features to support the skull. • Small bodies. • Transverse foramen for vertebral arteries. • Spinous processes of cervical vertebrae 2-6 are bifid (aka, bifurcated). Thoracic • 12 vertebrae that articulate with ribs to form posterior wall of thoracic cage. • Bodies have costal facets for articulations with the ribs. • Spinous processes are typically longer and angled inferiorly. • Transverse processes have costal facets for articulation with ribs. Lumbar • 5 vertebrae of the lower back. • Large bodies. • Spinous processes are typically short, and more horizontally oriented. • Short transverse processes. Sacral/Coccygeal • 5 fused sacral bones. 1 / 2 • 3-4 fused coccygeal bones. • Contribute to posterior wall of the pelvis. General Features of Vertebrae: Vertebral body (aka, centrum) • The disc-shaped weight-bearing portion of the vertebra. Vertebral (aka, neural) arch • Pedicles • Laminae • Transverse processes • Spinous process • Superior and inferior articular processes for articulation with vertebrae above and below Vertebral foramen • Space between body and arch • When stacked, vertebral foramina create vertebral canal, through which spinal cord passes Intervertebral foramen • Where spinal nerves pass through vertebral column laterally Intervertebral disc • Absorbs shock and acts as a cushion between the vertebrae, and allows for spinal flexibility. • It comprises: - The nucleus pulposus, which is an inner gelatinous substance - The anulus fibrosus is the outer ring of collagen and cartilage that encloses the nucleus pulposus Clinical correlations: • Distorted spinal curvatures can be caused by poor posture, aging, disease, and other factors. • Scoliosis, which is a common curvature abnormality, is characterized by a lateral curvature of the vertebral column. • Herniated intervertebral discs are common; they occur when a fissure in the annulus fibrosus allows the nucleus pulposus to bulge and compress nearby nerves, which can cause deficits and pain.

Vertebral Column and Thorax
Introduction to Human Osteology Chapter 4: Vertebral Column and Thorax Roberta Hall Kenneth Beals Holm Neumann Georg Neumann Gwyn Madden Revised in 1978, 1984, and 2008 The Vertebral Column and Thorax Sternum Manubrium – bone that is trapezoidal in shape, makes up the superior aspect of the sternum. Jugular notch – concave notches on either side of the superior aspect of the manubrium, for articulation with the clavicles. Corpus or body – flat, rectangular bone making up the major portion of the sternum. The lateral aspects contain the notches for the true ribs, called the costal notches. Xiphoid process – variably shaped bone found at the inferior aspect of the corpus. Process may fuse late in life to the corpus. Clavicle Sternal end – rounded end, articulates with manubrium. Acromial end – flat end, articulates with scapula. Conoid tuberosity – muscle attachment located on the inferior aspect of the shaft, pointing posteriorly.

Lab #23 Anal Triangle
THE BONY PELVIS AND ANAL TRIANGLE (Grant's Dissector [16th Ed.] pp. 141-145) TODAY’S GOALS: 1. Identify relevant bony features/landmarks on skeletal materials or pelvic models. 2. Identify the sacrotuberous and sacrospinous ligaments. 3. Describe the organization and divisions of the perineum into two triangles: anal triangle and urogenital triangle 4. Dissect the ischiorectal (ischioanal) fossa and define its boundaries. 5. Identify the inferior rectal nerve and artery, the pudendal (Alcock’s) canal and the external anal sphincter. DISSECTION NOTES: The perineum is the diamond-shaped area between the upper thighs and below the inferior pelvic aperture and pelvic diaphragm. It is divided anatomically into 2 triangles: the anal triangle and the urogenital (UG) triangle (Dissector p. 142, Fig. 5.2). The anal triangle is bounded by the tip of the coccyx, sacrotuberous ligaments, and a line connecting the right and left ischial tuberosities. It contains the anal canal, which pierced the levator ani muscle portion of the pelvic diaphragm. The urogenital triangle is bounded by the ischiopubic rami to the inferior surface of the pubic symphysis and a line connecting the right and left ischial tuberosities. This triangular space contains the urogenital (UG) diaphragm that transmits the urethra (in male) and urethra and vagina (in female). A. Anal Triangle Turn the cadaver into the prone position. Make skin incisions as on page 144, Fig. 5.4 of the Dissector. Reflect skin and superficial fascia of the gluteal region in one flap to expose the large gluteus maximus muscle. This muscle has proximal attachments to the posteromedial surface of the ilium, posterior surfaces of the sacrum and coccyx, and the sacrotuberous ligament.

Anatomy of the Spine
12 Anatomy of the Spine Overview The spine is made of 33 individual bones stacked one on top of the other. Ligaments and muscles connect the bones together and keep them aligned. The spinal column provides the main support for your body, allowing you to stand upright, bend, and twist. Protected deep inside the bones, the spinal cord connects your body to the brain, allowing movement of your arms and legs. Strong muscles and bones, flexible tendons and ligaments, and sensitive nerves contribute to a healthy spine. Keeping your spine healthy is vital if you want to live an active life without back pain. Spinal curves When viewed from the side, an adult spine has a natural S-shaped curve. The neck (cervical) and low back (lumbar) regions have a slight concave curve, and the thoracic and sacral regions have a gentle convex curve (Fig. 1). The curves work like a coiled spring to absorb shock, maintain balance, and allow range of motion throughout the spinal column. The muscles and correct posture maintain the natural spinal curves. Good posture involves training your body to stand, walk, sit, and lie so that the least amount of strain is placed on the spine during movement or weight-bearing activities. Excess body weight, weak muscles, and other forces can pull at the spine’s alignment: • An abnormal curve of the lumbar spine is lordosis, also called sway back. • An abnormal curve of the thoracic spine is Figure 1. (left) The spine has three natural curves that form kyphosis, also called hunchback. an S-shape; strong muscles keep our spine in alignment.

Occipital Neuralgia: a Literature Review of Current Treatments from Traditional Medicine to CAM Treatments
Occipital Neuralgia: A Literature Review of Current Treatments from Traditional Medicine to CAM Treatments By Nikole Benavides Faculty Advisor: Dr. Patrick Montgomery Graduation: April 2011 1 Abstract Objective. This article provides an overview of the current and upcoming treatments for people who suffer from the signs and symptoms of greater occipital neuralgia. Types of treatments will be analyzed and discussed, varying from traditional Western medicine to treatments from complementary and alternative health care. Methods. A PubMed search was performed using the key words listed in this abstract. Results. Twenty-nine references were used in this literature review. The current literature reveals abundant peer reviewed research on medications used to treat this malady, but relatively little on the CAM approach. Conclusion. Occipital Neuralgia has become one of the more complicated headaches to diagnose. The symptoms often mimic those of other headaches and can occur post-trauma or due to other contributing factors. There are a variety of treatments that involve surgery or blocking of the greater occipital nerve. As people continue to seek more natural treatments, the need for alternative treatments is on the rise. Key Words. Occipital Neuralgia; Headache; Alternative Treatments; Acupuncture; Chiropractic; Nutrition 2 Introduction Occipital neuralgia is a type of headache that describes the irritation of the greater occipital nerve and the signs and symptoms associated with it. It is a difficult headache to diagnose due to the variety of signs and symptoms it presents with. It can be due to a post-traumatic event, degenerative changes, congenital anomalies, or other factors (10). The patterns of occipital neuralgia mimic those of other headaches.

Changes in L4/5 Intervertebral Foramen Bony Morphology With
www.nature.com/scientificreports OPEN Changes in L4/5 Intervertebral Foramen Bony Morphology with Age Received: 7 September 2017 Shuaifeng Yan, Kai Wang, Yunfan Zhang, Song Guo, Yan Zhang & Jun Tan Accepted: 1 May 2018 The purpose of this study was to explore the morphological changes in L4/5 intervertebral foramen Published: xx xx xxxx with age using a digital method. The closed boundaries of the intervertebral foramen (IGES) in diferent sagittal slices (inside, middle and outside) were obtained from Mimics, and then imported to a custom- written program, which provided quantitative distance between the nerve root and the closed curves. The quantitative information of each age group was used to produce radar chart and line chart for morphological and statistical analyses. Overall, the intervertebral foramen changes mainly occurred in the inner part from middle age to old age. The foraminal height decreased with age in the inside sagittal slice, while no signifcant diference was found in the middle sagittal slice or the outside sagittal slice. The foraminal width showed no decrease in each age group or each sagittal plane. The present study described foraminal geometry of asymptomatic males in diferent sagittal slices with age. This information enhances the knowledge of anatomical changes in intervertebral foramen with age, which provides better understanding of the pathology of intervertebral foramen diseases. Low back pain (LBP) is a global health problem, causing enormous fnancial burden1,2. Te lifetime prevalence of LBP is reported to be as high as 84%3. Radiculopathy is a common cause of low back and leg pain4. In general, radiculopathy caused by foramen stenosis consists of 8–11% nerve root compression5, and shows an increasing trend6.
