#VERTEBRAL ARCH ARTICULAR PROCESSES SKIN#

The cervical spine is highly mobile compared to the thoracic or lumbar spine. The cervical spine comprises of the first 7 vertebrae, which form the neck. The spine can be divided into 4 parts: cervical, thoracic, lumbar and sacral region. The purpose of the canal is to create a bony casing from the head to the lower back, through which the spinal cord passes. The spinal canal is formed by the placement of single vertebral foramina one on top of the other to form a canal. The spinous process forms a steeple at the apex of the laminae and is the part of our spine that is felt directly under the skin. The transverse processes spread out from the side of the pedicles like wings and help to anchor the surrounding muscle to the vertebral arch. The laminae of the vertebra can be described as a pair of flat-arched bones that form a component of the vertebral arch. Two strong pedicle bones join the vertebral arch to the body of the vertebrae. The body is cylindrical in shape, strong and stable.

Parts of a VertebraĪ single vertebra is made up of two parts, the front portion is called the body and the back portion is referred to as the vertebral or neural arch. The vertebrae and disks form the spinal column from the neck to the pelvis, giving symmetry and support to the body. It is made up of bony segments called vertebrae with fibrous tissue called intervertebral disks between them. The spine, also called the backbone, plays a vital role in stability, smooth movement and protection of the delicate spinal cord. When the vertebrae are articulated, contributes to the formation of the intervertebral foramina.Cervical Spine Anatomy Anatomy of the Spine Inferior Notch - a concavity on the inferior aspect of the pedicle.The dens articulates with the atlas, where it is held in place by the transverse ligament Odontoid Process (aka Dens) - a bony projection that extends upward from the vertebral body of C2.Transverse Foramen - an opening on the transverse process of cervical vertebrae houses an artery that supplies the brain.Axis - the second cervical (C2) vertebra forms the moveable atlanto-axial joint allowing for head rotation.Atlas - the first cervical (C1) vertebra: does not have a body or spinous process- shaped like a ring forms the atlanto-occipital joint.Vertebral Foramen - a large opening between the vertebral arch and the body houses the spinal cord.Centrum (body) - the main, weight-supporting part of a vertebra the anterior part of the vertebra.Pedicle - the lateral part of the vertebral arch anchored to the posterior side of the vertebral body.

Lamina - the posterior part of the vertebral arch found between the transverse and spinous process.Inferior Articular Process - a paired downward projection.

Superior Articular Process - a paired upward projection the superior articular processes of one vertebra join with the corresponding inferior articular processes from the next superior vertebra.Transverse Process - a paired lateral projection arises from the junction point between the pedicle and the lamina.

The vertebral spines can easily be felt as a series of bumps just under the skin down the middle of the back. Spinous Process (vertebral spine) - a single posterior projection at the midline.AP2 Lab Module 15 The Reproductive System: assigned male at birth.AP2 Lab Module 14 The Reproductive System: assigned female at birth.AP2 Lab Module 13 Selected Endocrine Glands.AP2 Lab Module 11 Digestive Accessory Glands.AP2 Lab Module 10 Respiratory Physiology.AP2 Lab Module 6 Lower Extremity Blood Vessels.AP2 Lab Module 5 Upper Extremity Blood Vessels.AP2 Lab Module 4 Selected Systemic Arteries and Veins.AP2 Lab Module 2 Great Blood Vessels and Coronary Circulation.AP1 Lab Module 11 Muscle tissue and the skin.
