Whats is Cervical ?
The human skeleton is comprised of several bones that maintains the posture of the body. The spinal cord is compact arrangement of all the miniature bones that originates after the skull bones ends and continues till the distal part of the pelvic region. The spinal cord is the longitudinal arrangement of bones that are differentiated from each other by the intervertebral discs.
Spinal cord is divided into five regions depending on the positioning of the bones. It starts with the cervical bones followed by thoracic, lumbar, sacral and coccygeal regions. Cervical is the region that comprises of 7 seven bones that are interconnected with each other with the help of intervertebral discs. It has C1, C2, C3, C4, C5, C6 and C7. It forms the beginning of the spinal cord and it is responsible for carrying various nerves and arteries. Cervical bones are also called as cervical vertebrae. Cervical vertebrae consist of the seven vertebrae and the most important among them are first two vertebrae. The first one being atlas and the second one is axis. The movement or rotation of the skull in all the direction is possible by the flexion and the extension movements of atlas and axis.
types of Cervical
The cervical spine consists of seven bones also called vertebrae. It connects the skull from the medulla oblongata to the thoracic region. The first cervical bone is the atlas that is designed naturally in such a way, that it can handle the weight of the skull and also supports the flexible movement of the head and neck. The second vertebrae followed by the atlas is called axis. These two are interconnected with each other and are intersected in each other. These two have the distinct shape and size while the vertebrae from C3 to C6 are typical vertebrae that at last connect the thoracic vertebrae. The improper functioning of these vertebrae or the malformation leads to various diseases.
The various diseases associated with cervical are spondylosis, cervical herniated disc, degenerative disc disease and cervical spinal stenosis.
- Cervical spondylosis: in this condition, the cervical vertebrae mainly the atlas and axis wear out abnormally due to friction. The cartilage or the vertebrae tends to get wear out. This leads to various symptoms of cervical spondylosis like neck pain, nausea, vomiting, immobility, reduces movement of the neck joint, etc.
- Cervical herniated disc: the vertebrae are connected with the cervical discs. These cervical discs tend to get ruptured and they protrude out between these vertebrae causing severe and unbearable pain.
- Degenerative disc disease: the interconnecting discs are so crucial connecting points that any dislocation or disturbance can cause severe pain and discomfort.
- Cervical spinal stenosis: the spinal cord has circular, hollow structure that carries the nerves and the blood vessels within. In Cervical spinal stenosis, the spinal canal tends to get narrow. The narrowing of the spinal canal compresses the blood vessels and the narteries.
- Cervical lymphadenopathy: it is the disease of the lymph nodes that develop in the neck region.
- Cervical lordosis: The spinal bone in the cervical region tends to lose the curvature. This is called cervical lordosis.
