In tetrapods, cervical vertebrae (sg.: vertebra) are the vertebrae of the neck, immediately below the skull. Truncal vertebrae (divided into thoracic and lumbar vertebrae in mammals) lie caudal (toward the tail) of cervical vertebrae. [ 1 ] In sauropsid species, the cervical vertebrae bear cervical ribs. In lizards and saurischian dinosaurs ...
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.
Divisions. The posterior triangle is crossed, about 2.5 cm above the clavicle, by the inferior belly of the omohyoid muscle, which divides the space into two triangles: an upper or occipital triangle. a lower or subclavian triangle (or supraclavicular triangle)
Common carotid artery. The common carotid artery arises directly from the aorta on the left and as a branch of the brachiocephalic trunk on the right. In anatomy, the left and right common carotid arteries (carotids) (English: / kəˈrɒtɪd / [1][2]) are arteries that supply the head and neck with oxygenated blood; they divide in the neck to ...
The posterior divisions of the lower five cervical nerves divide into medial and lateral branches. The medial branches of the fourth and fifth run between the Semispinales cervicis and capitis, and, having reached the spinous processes, pierce the Splenius and Trapezius to end in the skin. Sometimes the branch of the fifth fails to reach the ...
The spinal cord is a long, thin, tubular structure made up of nervous tissue that extends from the medulla oblongata in the lower brainstem to the lumbar region of the vertebral column (backbone) of vertebrate animals. The center of the spinal cord is hollow and contains a structure called the central canal, which contains cerebrospinal fluid.
6961. Anatomical terms of neuroanatomy. [edit on Wikidata] The inferior cervical ganglion is one of the three cervical sympathetic ganglia (i.e. of the cervical portion of the sympathetic trunk). [1] It is situated between the base of the transverse process of the last cervical vertebra and the neck of the first rib, on the medial side of the ...
In anatomy, Luschka's joints (also called uncovertebral joints, neurocentral joints) [1] are formed between uncinate process or "uncus" below and uncovertebral articulation above. [2] They are located in the cervical region of the vertebral column from C3 to C7. [3] Two lips project upward from the superior surface of the vertebral body below ...
