The cervical enlargement corresponds with the attachments of the large nerves which supply the upper limbs. Located just above the brachial plexusit extends from about the fifth cervical to the first thoracic vertebraits maximum vertebrae cervicales nedir about 38 mm.

The human head and neck are supported by the cervical spine, which consists of seven vertebral bones and joints between them. The spinal cord passes through the vertebral canal inside the cervical spine. At each vertebra level, the spinal cord gives off a pair of nerves that travel in the intervertebral foramen to exit the spine. These nerves provide signals to and from the spinal cord. Each pair of vertebral bones is connected with one big disc joint and two smaller facet joints.

The anticlinal vertebra is a point in the caudal thoracic vertebral column at which vertebral anatomic features change: the spinous process is perpendicular to the body and the preceding vertebrae incline caudally. It may be used as a point of reference in diagnostic imaging studies but differs between species and in subspecies T16 in the horse, T11 in the big or medium dogs, T10 in small dogs, and T11 to T13 in the ox.

Sometimes, the pain may also spread to the back of the neck, head, and between shoulder blades.

A cervical rib in humans is an extra rib which arises from the seventh cervical vertebra. Their presence is a congenital abnormality located above the normal first rib. A cervical rib is estimated to occur in 0. Most cases of cervical ribs are not clinically relevant and do not have symptoms; [7] [8] cervical ribs are generally discovered incidentally , most often during x-rays and CT scans. A cervical rib represents a persistent ossification of the C7 lateral costal element. Failure of this process results in a variably elongated transverse process or complete rib that can be anteriorly fused with the T1 first rib below. On imaging, cervical ribs can be distinguished because their transverse processes are directed inferolaterally, whereas those of the adjacent thoracic spine are directed anterolaterally.

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. Yet, in spite of their size, the cervical vertebrae have the huge jobs of supporting the head, protecting the spinal cord, and providing mobility to the head and neck. The cervical vertebrae are stacked along the length of the neck to form a continuous column between the skull and the chest. The C1 vertebra, which holds up the skull, is named the atlas after the mythological titan Atlas who similarly held the Earth on his shoulders. Similar to the C1 vertebra, the C2 vertebra is named the axis as it provides the axis upon which the skull and atlas rotate when the head is moved side to side. Each cervical vertebra consists of a thin ring of bone, or vertebral arch , surrounding the vertebral and transverse foramina. The vertebral foramen is a large opening in the center of the vertebra that provides space for the spinal cord and its meninges as they pass through the neck. Flanking the vertebral foramen on each side are the much smaller transverse foramina.

In some instances, cervical stenosis produces very few symptoms because the spinal cord and nerves have time to adapt. Instead of fusing the vertebral bones together and losing mobility at that segment of the cervical spine, an artificial joint is placed, which serves as a substitute for the removed disc joint. The nucleus is made up of a unique, gel-like substance and serves as an elastic pillow between the neighbor bones. Prev Previous Spinal Tumor. MRI, on the other hand, is an excellent tool for demonstrating soft tissues like the spinal cord, nerves, and ligaments. In birds , the cervical ribs are small and completely fused to the vertebrae. ISBN It may be used as a point of reference in diagnostic imaging studies but differs between species and in subspecies T16 in the horse, T11 in the big or medium dogs, T10 in small dogs, and T11 to T13 in the ox. Nerve exit foramina, therefore, gets narrower, resulting in nerve pinching. Typical radicular pain starts in the neck and radiates to the arm. Obtaining a history of the disease and meticulous examination is sufficient to suspect the diagnosis. These nerves provide signals to and from the spinal cord. Neurological examination with complete motor and sensory assessment is absolutely necessary since patients might be unaware of their deficits. Read Edit View history. PMID
