The vertebral column is a series of approximately 33 bones called vertebrae, which are separated by intervertebral discs.. The column can be divided into five different regions, with each region characterised by a different vertebral structure.. In this article, we shall look at the anatomy of the vertebral column - its function, structure, and clinical significance The vertebral column is also known as the spinal column or spine (Figure 1). It consists of a sequence of vertebrae (singular = vertebra), each of which is separated and united by an intervertebral disc.Together, the vertebrae and intervertebral discs form the vertebral column The human vertebral column : Overview. The vertebral column is bony - it is strong, yet it is flexible, as it comprises a number of smaller bones. Its successively lower parts bear the weight of the trunk above and the column transmits the weight of the body to the lower limbs. It contains and protects the spinal cord, a delicate part of th

Vertebral Column. The vertebral column (spine) consists of 26 vertebrae bones (Table 1). It provides support for the head and trunk of the body, protection for the spinal cord, and connecting points for the ribs and muscles.

Vertebral Column The spine consists of a curved stack of 33 vertebrae divided structurally into five regions ( Figure 9-1 ). Proceeding from superior to inferior, there are 7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, 5 fused sacral vertebrae, and 4 small, fused coccygeal vertebrae Macroscopic bony anatomy of the spine. From Clemente Anatomy. The junctions between the broad regions, i.e., the cervicothoracic, thoracolumbar, and lumbosacral junctions, frequently are sites for degenerative changes over the long term, most likely due to the abrupt change in stiffness that occurs at these junctions Spinal Cord Anatomy. In adults, the spinal cord is usually 40cm long and 2cm wide. It forms a vital link between the brain and the body. The spinal cord is divided into five different parts. Several spinal nerves emerge out of each segment of the spinal cord. There are 8 pairs of cervical, 5 lumbar, 12 thoracics, 5 sacral and 1 coccygeal pair. This radioanatomy module of the spinal column presents 18 conventional radiographs of the spine with 192 anatomical structures labeled.

The term vertebral column describes the entire set of vertebrae excluding the ribs, sternum, and pelvis ( Fig. 22-1 ). The normal vertebral column is made up of 29 vertebrae (7 cervical, 12 thoracics, 5 lumbar, and 5 sacral) and three or four coccygeal segments. The adage that function follows form is very much applicable when studying. Spinal cord lies in the vertebral canal which is located in the middle of vertebral column (5,10,12). Spinal dura mater: It extends from foramen mag-num to the second sacral vertebra. Spinal cord is en-closed in a tube shaped dura mater. The lower end descends to the coccyx forming a fibrous band (coc-cygeal ligament) (1,2,7)

The spinal column is made up of 33 vertebrae that are separated by spongy discs. The spine is divided into distinct areas: cervical, thoracic, lumbar and sacral. Ligaments and muscles connect the bones together and keep them aligned. The spinal column provides the main support for the body, allowing a person to stand upright, bend, and twist Emerging from the spinal cord are 31 pairs of anterior and posterior nerve roots. The cervical, thoracic, lumbar, and sacral portions of the spinal cord are defined according to the segmental division of the vertebral column and spinal nerves. There are eight cervical*, twelve thoracic, five lumbar, five sacral and one coccygeal

The curvature in the cervical spine is called lordosis and it's concave part faces posterior. Similar shape and name has the curvature of the bottom of the spine namely the lumbar spine.

Breast, prostate and lung cancer are responsible for more than 80% of cases of metastatic bone disease. The spine is the most common site of bone metastasis. A spinal metastasis may cause pain, instability and neurological injuries

ADVERTISEMENTS: The vertebral column of fishes has two types of vertebrae, trunk vertebrae and caudal vertebrae; the anus marks the point of transition between the two types of vertebrae. The vertebrae are amphicoelous. Types of tails or caudal fins: In fishes the shape of the tail is correlated with the direction taken by the terminal [ Introduction. Interventional diagnostic procedures and pathologies of the vertebral column, potentially requiring surgery, have been described in pet rabbits (Oryctolagus cuniculus) (Whittington and Bennett, 2011, Gasper et al., 2014, Meredith and Richardson, 2015); however, various numbers of vertebrae in rabbits have been described and different vertebral formulas have been published. The spinal cord is situated within the vertebral canal of the vertebral column and is surrounded by 3 meninges: the dura mater, the arachnoid mater, and the pia mater. Further protection is provided by the cerebrospinal fluid, which surrounds the spinal cord in the subarachnoid space The anatomy of the developing cervical spine predisposes children to injury of the upper cervical spine. In general, the younger the child, the more likely an upper cervical spine injury will occur. Because of their unique anatomy, younger children tend to have more injuries located from the occiput to the C2-C3 vertebral level 1. Introduction. The spine is a complex multi-articular system controlled by the muscles which supports the head and trunk during posture and movements and encloses and protects the spinal cord, nerve roots and, at cervical level, the vertebral arteries. The normal function of the spine presupposes its stability

Spinal nerves are distributed approximately evenly along the spinal cord and spine. The spine is a column of vertebral bones that protects and surrounds the spinal cord. Each spinal nerve exits the spine by traveling through the foramen, which are openings at the right and left sides of the vertebral bones of the spine See Lumbar Spine Anatomy and Pain. Approximately 50% of flexion (bending forward) occurs at the hips, and 50% occurs at the lumbar spine (lower back).

Scoliosis is a lateral, or sideways, deviation of the spine, or vertebral column. The condition usually includes two curves—the original abnormal curve and As the vertebral column grows, these nerves grow with it and result in a long bundle of nerves that resembles a horse's tail and is named the cauda equina. The sacral spinal cord is at the level of the upper lumbar vertebral bones. The spinal nerves extend from their various levels to the proper level of the vertebral column.
