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 ...
The cervix uteri (neck of the uterus) is thus the uterine cervix, but in English the word cervix used alone usually refers to it. Thus the adjective cervical may 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).
The spinal nerves arise from the spinal column. The top section of the spine is the cervical section, which contains nerves that innervate muscles of the head, neck and thoracic cavity, as well as transmit sensory information to the CNS. The cervical spine section contains seven vertebrae, C-1 through C-7, and eight nerve pairs, C-1 through C-8.
In anatomy, the neck is also referred to as the cervix or collum. 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 ...
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 SCG receives pre-ganglionic sympathetic afferents from the ciliospinal center which synapse in the ganglion. Post-ganglionic efferents then leave the SCG and join the internal carotid nerve plexus of the internal carotid artery, accompanying first this artery and subsequently its branches to reach the orbit and ultimately innervate the dilator pupillae muscle to mediate pupillary dilatation.
This fragment of the spine starts from the region above the shoulder blades and ends by supporting and connecting the skull. [1] The cervical spine contains many different anatomic compositions, including muscles, bones, ligaments, and joints. All of these structures have nerve endings that can detect painful problems when they occur.
The cervical spinal nerve 7 (C7) is a spinal nerve of the cervical segment. [1] It originates from the spinal column from above the cervical vertebra 7 (C7). It runs through the interspace between the C6 and C7 vertebrae.
