The vertebrae that make up the cervical spine are the smallest seven within the spinal column. These bones give the neck structure, support the skull, and protect the spinal cord, among other functions.

Also, what do you mean by cervical vertebrae? Cervical Vertebrae Definition. The cervical vertebrae are the seven cylindrical bones, or vertebral bodies (C1-C7), that provide support and structure for the cervical spine. Save. Watch: Cervical Spine Anatomy Video. The vertebral body is the large portion of the bone that lies anterior (in front of) the spinal cord.

Keeping this in view, how is the cervical vertebrae different?

In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass.

What are the unique features of cervical vertebrae?

There are seven cervical vertebrae in the human body. They have three main distinguishing features: Bifid spinous process – the spinous process bifurcates at its distal end. Exceptions to this are C1 (no spinous process) and C7 (spinous process is longer than that of C2-C6 and may not bifurcate).

What are the seven vertebrae in the neck called?

Overview. These are the seven bones of the neck, called the cervical vertebra. The top bone, seen on the right of this picture, is called the atlas, and is where the head attaches to the neck. The second bone is called the axis, upon which the head and atlas rotate.

What are the functions of the neck?

The neck supports the weight of the head and protects the nerves that carry sensory and motor information from the brain down to the rest of the body. In addition, the neck is highly flexible and allows the head to turn and flex in all directions.

What movement does c1 allow and why?

The second vertebra, C2, is called the axis for its purpose of motion. When together, atlas C1 and axis C2 allow for rotation and swiveling of the head since the C1 vertebrae is attached directly into the skull and pivots from its C2 axis.

Where is the c5 c6 vertebrae located?

The C5-C6 spinal motion segment (located in the lower cervical spine just above the C7 vertebra) provides flexibility and support to much of the neck and the head above.

What nerves are affected by c3 and c4?

Cervical Nerve Functions

C1, C2, and C3 (the first three cervical nerves) help control the head and neck, including movements forward, backward, and to the sides.
C4 helps control upward shoulder movements.

What are the symptoms of a c3 c4 disc herniation?

Why does my c7 vertebrae stick out?

Causes of Dowenger's hump The spinus process of the C7 vertebrae is anatomically larger than the rest of the cervical spine processes. If this is the only cause of the hump there is little to do. Most everyone has this bony protuberance sticking out more than the others. Loss or reversal of spinal curvature.

What nerves are affected by c4 c5?

C5, as mentioned earlier, along with C3 and C4, contributes to the phrenic nerve that innervates the diaphragm. Roots C5, C6, and C7 produce the long thoracic nerve, responsible for controlling the serratus anterior.

Can c3 c4 cause headaches?

It has been reported that pain from the C2-3 and C3-4 cervical facet joints can radiate to the occipital area, frontotemporal and even periorbital regions. Even pathology in C5 or C6 nerve roots have been reported to cause headache. This headache does not respond well to migraine medications.

Why is it called cervical spine?

Medical Definition of C1-C7 (cervical vertebrae) It supports the head and is named for the Greek god Atlas who was condemned to support the earth and its heavens on his shoulders. (Because the god Atlas often adorned maps, a compilation of maps came to be known as an atlas).

Conservative treatment includes time, medication, brief bed rest, reduction of strenuous physical activity and physical therapy. A doctor may prescribe medications to reduce the pain or inflammation and muscle relaxants to allow time for healing to occur.

Does cervical spine need surgery?

If cervical degeneration causes myelopathy (spinal cord dysfunction), radiculopathy (dysfunction of nerves to the neck or arms), neck pain, or abnormal neck motion, surgery may be necessary. The surgical goal is to reduce pain and restore spinal stability.
