In humans, cervical vertebrae are the smallest of the true vertebrae and can be readily distinguished from those of the thoracic or lumbar regions by the presence of a foramen (hole) in each transverse process, through which the vertebral artery, vertebral veins, and inferior cervical ganglion pass. The remainder of this article focuses upon ...
However, when the term cervix is used alone, it often refers to the uterine cervix, the neck of the uterus. [3] Therefore, the adjective cervical can refer either to the neck (as in cervical vertebrae or cervical lymph nodes) or to the uterine cervix (as in cervical cap or cervical cancer).
In the whale, the cervical vertebrae are typically fused, an adaptation trading flexibility for stability during swimming. [28] [29] All mammals except manatees and sloths have seven cervical vertebrae, whatever the length of the neck. [30] This includes seemingly unlikely animals such as the giraffe, the camel, and the blue whale, for example.
The articulating vertebrae are named according to their region of the spine. From top to bottom, there are 7 cervical vertebrae, 12 thoracic vertebrae and 5 lumbar vertebrae. The number of those in the cervical region, however, is only rarely changed, [4] while that in the coccygeal region varies most. [5]
In anatomy, the atlas (C1) is the most superior (first) cervical vertebra of the spine and is located in the neck.. The bone is named for Atlas of Greek mythology, just as Atlas bore the weight of the heavens, the first cervical vertebra supports the head. [1]
The cervical spinal nerve 8 (C8) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from below the cervical vertebra 7 (C7). [2]
The inferior processes or postzygapophysis project downward from a higher vertebra, and their articular surfaces are directed more or less forward and outward. The articular surfaces are coated with hyaline cartilage. In the cervical vertebral column, the articular processes collectively form the articular pillars. These are the bony surfaces ...
Referred seventh cervical vertebra As a consequence of its robust, thick-walled vertebrae, the neck of Hatzegopteryx was much stronger than that of Arambourgiania . This can be quantified using relative failure force, which is the bone failure force of a vertebra divided by the body weight of the pterosaur that it belongs to, estimated at 180 ...
