Your cervical spine — the neck area of your spine — consists of seven stacked bones called vertebrae. The first two vertebrae of your cervical spine are unique in shape and function. Your first vertebra (C1), also called the atlas, is a ring-shaped bone that begins at the base of your skull.
It consists of 7 bones, from top to bottom, C1, C2, C3, C4, C5, C6, and C7. In tetrapods, cervical vertebrae (sg.: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae. [ 1 ]
The neck, also called the cervical spine, is a well-engineered structure of bones, nerves, muscles, ligaments, and tendons. The cervical spine is delicate—housing the spinal cord that sends messages from the brain to control all aspects of the body—while also remarkably strong and flexible, allowing the neck to move in all directions.
The neck is the start of the spinal column and spinal cord. The spinal column contains about two dozen inter-connected, oddly shaped, bony segments, called vertebrae. The neck contains seven of...
Your neck, also known as the cervical spine, is a complex series of bones, discs, muscles, nerves, and ligaments. There are seven bones, each called a cervical vertebra, that are stacked upon one another.
Bones of the Neck. The cervical spine and the hyoid bone constitute the bones of the neck. The cervical spine is comprised of the 7 uppermost vertebrae of the vertebral column. C3 to C6 are the typical cervical vertebrae characterised by the presence of transverse foramina and, in many people, by their bifid spinous processes.
The skeleton of the neck is formed by the cervical vertebrae, the hyoid bone, and the manubrium of the sternum which are part of the axial skeleton, as well as the clavicles which are part of the appendicular skeleton.
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 cervical vertebrae of the spine consist of seven bony rings that reside in the neck between the base of the skull and the thoracic vertebrae in the trunk. Among the vertebrae of the spinal column, the cervical vertebrae are the thinnest and most delicate bones.

The Cervical Spine. Written by Sam Barnes. Last updated September 5, 2024 • 59 Revisions •. The cervical spine is the most superior portion of the vertebral column, lying between the cranium and the thoracic vertebrae. It consists of seven distinct vertebrae, two of which are given unique names:
The cervical spine also allows passage of important vasculature to reach the brain and provides attachment sites for muscles that move the head, neck, and shoulder girdle.
Spinal Cord Anatomy in the Neck. Cervical Spine Anatomy Video. Typical Cervical Vertebrae: C3, C4, C5, and C6. C3, C4, C5, and C6 cervical vertebrae share characteristics with most of the vertebrae throughout the spine.
Explore the anatomy and vital role of the head and neck bones with Innerbody's interactive 3D model. The bones of the head and neck play the vital role of supporting the brain, sensory organs, nerves, and blood vessels of the head and protecting these structures from mechanical damage.
Cervical Spine Anatomy (Neck) Learn about the complex structure of bones, discs, muscles, ligaments, nerves, and tendons that make up the neck. Updated Jan 4, 2022. By. Lindsay Curtis Joshua M....
Neck, in land vertebrates, the portion of the body joining the head to the shoulders and chest. Some important structures contained in or passing through the neck include the seven cervical vertebrae and enclosed spinal cord, the jugular veins and carotid arteries, part of the esophagus, the larynx.
Introduction. The spine, or vertebral column, is a segmental set of 33 bones and associated soft tissues in the subcranial portion of the axial skeleton. It is subdivided into 5 regions based on curvature and morphology: cervical, thoracic, lumbar, sacral, and coccygeal (see Image. Vertebral Column).
There are many muscles around the neck that help to support the cervical spine and allow you to move your head in different directions. Here is a list of the many muscles that exist in the neck. Longus Colli & Capitis – Responsible for flexion of the head and neck.
The content of the neck is grouped into 4 neck spaces, called the compartments. Vertebral compartment : contains cervical vertebrae and postural muscles. Visceral compartment : contains glands ( thyroid , parathyroid , and thymus ), the larynx , pharynx and trachea .
Introduction. The neck refers to the collection of structures that connect the head to the torso. It is a complex structure of many bones, muscles, nerves, blood vessels, lymphatics, and other connective tissues. The cervical spine is the bony part of the neck. Its primary function is to support the skull while still allowing for movement.
Skull. The skull is a strong, bony capsule that rests on the neck and encloses the brain. It consists of two major parts: the neurocranium (cranial vault) and the viscerocranium (facial skeleton).
The neck is the part of the body on many vertebrates that connects the head with the torso. 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.
