In human anatomy, what can be cervical or thoracic, amongst others?
Cervical vertebrae are small and completely fused to the vertebrae. The vertebral transverse processes of mammals are homologous to the cervical ribs of other amniotes. Most mammals have 7 cervical vertebrae. 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 passes. The remainder of this article focuses upon human anatomy. By convention, the cervical vertebrae are numbered, with the first one (C1) closest to the
Cervical sinus cervical fistula) or with the pharynx (internal cervical fistula). Prone to infection. Cervical sinus During Human embryogenesis the mandibular arch and hyoid arch grow more rapidly than those behind them, with the result that the latter become, to a certain extent, telescoped within the former, and a deep depression, the cervical sinus, is formed on either side of the neck. This sinus is bounded in front by the hyoid arch, and behind by the thoracic wall; it is ultimately obliterated by the fusion of its walls. Formed by the walls of the 2-4th pharyngeal grooves merging. Sometimes it can remain
