Vertebra of the Neck In Depth: Vertebra of the Neck. The cervical spine consists of seven vertebrae, which are the smallest and uppermost in location within the spinal column. Together, the vertebrae support the skull, move the spine, and protect the spinal cord, a bundle of nerves connected to the brain. All seven cervical vertebrae are numbered. The C1, the first vertebra in the column (closest to the skull), is also known as the atlas.

Neck Muscles Neck Muscles. The neck is the part of the human body that attaches the head to the rest of the body. It is made up of many muscles that are connected from the head to the torso of the body. The purpose of the neck muscles is either to allow for neck movement or to provide structural support for the head. The motion is either rotation, meaning side-to-side; lateral flexion, meaning ear to shoulder; flexion, meaning chin to sternum; and hypertension, meaning looking up. Here is the list of muscles in the neck and head area: 1  Longus colli and capitis – this is found in the anterior neck area and is used for flexion. 2  Infrahyoid and suprahyoid – these muscles are for opening the jaw and for flexing the neck, and are found in the anterior neck area.

Understanding Spinal Anatomy: Overview of the Spine The neck region of the spine is known as the Cervical Spine. This region consists of seven vertebrae, which are abbreviated C1 through C7 (top to bottom). These vertebrae protect the brain stem and the spinal cord, support the skull, and allow for a wide range of head movement.The first cervical vertebra (C1) is called the Atlas. basic understanding of the spine’s anatomy and its functions is extremely important for patients with spinal disorders. This article provides a straightforward overview of the spine’s remarkable and complex anatomy.

Learn Muscle Anatomy: Scalene Muscles and Other Neck Anatomy SCALENE MUSCLES. The scalenes are a series of muscles that work like scaffolding, connecting the cervical vertebrae to the thoracic cage. The scalenes originate on the transverse processes of the cervical vertebrae (C02–C07) and attach to the first and second ribs of the thoracic cage.kay, basically they let me stuff my face, but the neck muscles do much more than that! The neck muscles (and neck anatomy on the whole) are responsible for head movement, stabilizing the upper region of the body, assisting in swallowing, helping to elevate the rib cage during inhalation, and more.

- It is commonly called the spine, or simply backbone. The articulating vertebrae are grouped into their regions; there are seven cervical vertebrae of the neck (C1 to C7); twelve thoracic vertebrae of the thorax (T1 to T12); and five lumbar vertebrae of the lower back above the pelvis (L1 to L5).ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.

Cervical Spine Anatomy (Neck) Vertebrae and Cervical Spinal Nerves. The cervical spine (sometimes abbreviated as c-spine in the medical world) begins at the base of the skull. Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7. The cervical nerves are also abbreviated; they are C1 through C8.

Seven vertebrae make up the cervical spine with eight pairs of cervical nerves. The individual cervical vertebrae are abbreviated C1, C2, C3, C4, C5, C6, and C7.he cervical bones (the vertebrae) are smaller in size when compared to other spinal vertebrae (in your thoracic or lumbar spines). The purpose of the cervical spine is to contain and protect the spinal cord, support the skull, and enable diverse head movement (eg, rotate side to side, bend forward and backward).

- The cervical spine refers to the uppermost portion of your backbone, which supports your head. Seven of the body's 24 spine bones, or vertebrae, make up the cervical spine. Four of the cervical spine bones are considered typical vertebrae.The remaining atypical cervical vertebrae are the atlas, axis and 7th cervical vertebra. Each of these bones has a distinctive structure and specialized function.eventh Cervical Vertebra. The 7th cervical vertebra is also considered atypical. It is actually quite similar in structure to the typical segments, but with a few distinctions. The most apparent difference is that the spinous process -- the pointy projection on the back side of the vertebra -- is quite elongated.

C3 The upper section of the cervical spine consists of the first cervical vertebrae (C1) and the second cervical vertebrae (C2). The lower section consists of the third cervical vertebrae (C3) through seventh cervical vertebrae (C7). These spinal bones attach to the thoracic spine and work together to support the head.

CERVICAL DEGENERATIVE DISC DISEASE Two vertebrae in the cervical spine, the atlas and the axis, differ from the other vertebrae because they are designed specifically for rotation. These two vertebrae are the reason your neck can move in so many directions. The atlas is the first cervical vertebra-the one that sits between the skull and the rest of the spine. The atlas does not have a vertebral body, but it does have a thick forward (anterior) arch and a thin back (posterior) arch with two prominent sideways masses.

Muscle of neck n vertebral column When all the erector spinae muscles contract together, they extend or hyperextend the vertebral column. the trunk, neck or head move laterally toward the contracting side. The movement is accomplished because the articular facets of the vertebrae glide on each other. Controls flexion, lateral flexion and rotation.
