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 vertebrae cervicales nedir 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, vertebrae cervicales nedir.

The cervical enlargement corresponds with the attachments of the large nerves which supply the upper limbs. Located just above the brachial plexus , it extends from about the fifth cervical to the first thoracic vertebra , its maximum circumference about 38 mm. The reason behind the enlargement of the cervical region is because of the increased neural input and output to the upper limbs. An analogous region in the lower limbs occurs at the lumbar enlargement.

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 disc joint has a soft and elastic inner core called nucleus pulposus and a tough outer ring — annulus fibrosus. The nucleus is made up of a unique, gel-like substance and serves as an elastic pillow between the neighbor bones. It provides mobility to the spine and serves as a shock absorption buffer. With aging, the nucleus pulposus loses water, shrinks, and breaks to pieces. Fragmented parts break through the annulus fibrosus and slip into the canal.

The spinal cord passes through the vertebral canal inside the cervical spine. Cervical enlargement labeled at upper right.

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.

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. These cervical vertebrae are specially shaped and configured to allow for maximum motion while supporting your skull and protecting your spinal cord, neighboring blood vessels, and nerves.
