Thecervical spineis the most superior portion of the vertebral column lying between the cranium and the thoracic vertebrae. The superior articular facets of the subaxial cervical spine C3-C7 are oriented in a posteromedial direction at C3 and posterolateral direction at.

It functions to provide mobility and stability to the head while connecting it to the relatively immobile thoracic spine.
Cervical spine anatomy. It is within this region that the nerves to the arms arise via the brachial plexus and where the cervical plexus forms providing innervation to the diaphragm among other structures. It functions to provide mobility and stability to the head while connecting it to. The cervical spine is the most superior portion of the vertebral column lying between the cranium and the thoracic vertebrae.
The neck is part of a long flexible column known as the spinal column or backbone which extends through most of the body. For each spinal nerve an anterior and posterior root join to form the completed nerve. This structure gives the spinal column great strength and shock-absorbing qualities.
The neck also called the cervical spine is a well-engineered structure of bones nerves muscles ligaments and tendons. From the osseous anatomy down to the soft tissues structures that function to stabilize maintain and protect the spinal cord clinicians must be able to appreciate the biomechanics and the complex anatomy. The top of the cervical spine connects to the skull and the bottom connects to the upper back at about shoulder level.
The cervical vertebrae gently curve inward while the thoracic spine curves gently outward followed by the lumbar spine which curves inward again. Shortly after branching out of the spinal cord the cervical nerves form the cervical and brachial plexuses. Gross Anatomy The cervical spine is made up of the first 7 vertebrae referred to as C1-7 see the images below.
The cervical portion of the spine is an important one anatomically and clinically. Cervical Spine Anatomy Neck Written by Joshua M. As viewed from the side the cervical spine forms a lordotic curve by gently curving toward the front of the body and then back.
The neck is unique in that it supports the weight of your head 10 to 11 pounds and allows a variety. The cervical spine your neck is a complex structure making up the first region of the spinal column starting immediately below the skull and ending at the first thoracic vertebra. The second cervical vertebrae.
The cervical spine neck region consists of seven bones C1-C7 vertebrae which are separated from one another by intervertebral discs. The cervical spine is the superior portion of the vertebral column extending between the cranium and the thoracic vertebrae. The cervical spine is made up of the first 7 vertebrae referred to as C1-7 see the images below.
The first cervical vertebrae C1 is known as the atlas. The delicate structure of the cervical spine which houses the spinal cord is very strong and flexible. The cervical spine may be divided into 2.
The first cervical vertebra is unique as it is a ring called the atlas that rotates around part of the second vertebrae the axis. The cervical spine has 7 stacked bones called vertebrae labeled C1 through C7. The cervical spine or neck begins at the base of the skull and through a series of seven vertebral segments connects to the thoracic or chest region of the spine.
This allows the neck to move in all directions. Cervical Spine Anatomy. Lets focus on the cervical spine its composed of seven vertebrae labelled C1 through to C7 and fibrocartilage discs known as intervertebral discs between each of the vertebrae like all things there are exceptions there are no discs between the skull occipital bone and the atlas C1 and no disc between the atlas C1 and the axis C2.
Cervical Spine American Association of Neurological Surgeons. The second cervical vertebrae C2 is known as the axis. Cervical Spine Anatomy Video.
The first cervical vertebrae C1 is known as theatlas. C2 Axis has an odontoid process dens that is tightly bound by transverse ligament to C1 Cervical spinal nerves C1-C7 exit about their corresponding Vertebra e In transitioning to Thoracic Spine C8 exits below the C7 Vertebra and above T1 In contrast all thoracic and lumbar spinal nerves exit below their corresponding Vertebra e. It consists of seven distinct vertebrae two of which are given unique names.
It consists of seven distinct vertebrae two of which are given unique names. The cervical nerves arise from the spinal cord in the form of rootlets or fila radicularia smaller neuron bundles that coalesce to form roots. The cervical spine starts just below the skull and terminates just above the thoracic spine.
An in depth understanding of cervical spine anatomy is essential to the diagnosis and management of cervical spine pathology. For patients managed operatively appropriate surgical. Cervical Spine Anatomy Clinical Significances Cervical Spine.
