  2. Cervical vertebrae - Wikipedia

    en.wikipedia.org/wiki/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 pass. The remainder of this article focuses upon ...

  3. Intervertebral disc - Wikipedia

    en.wikipedia.org/wiki/Intervertebral_disc

    An intervertebral disc (British English), also spelled intervertebral disk (American English), lies between adjacent vertebrae in the vertebral column.Each disc forms a fibrocartilaginous joint (a symphysis), to allow slight movement of the vertebrae, to act as a ligament to hold the vertebrae together, and to function as a shock absorber for the spine.

  4. Spinal column - Wikipedia

    en.wikipedia.org/wiki/Spinal_column

    The number of vertebrae in a region can vary but overall the number remains the same. In a human spinal column, there are normally 33 vertebrae. [3] The upper 24 pre-sacral vertebrae are articulating and separated from each other by intervertebral discs, and the lower nine are fused in adults, five in the sacrum and four in the coccyx, or tailbone.

  5. Vertebra - Wikipedia

    en.wikipedia.org/wiki/Vertebra

    In many species, though not in mammals, the cervical vertebrae bear ribs. In many groups, such as lizards and saurischian dinosaurs, the cervical ribs are large; in birds, they are small and completely fused to the vertebrae. The transverse processes of mammals are homologous to the cervical ribs of other amniotes. In the whale, the cervical ...

  6. Neck - Wikipedia

    en.wikipedia.org/wiki/Neck

    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 ...

  7. Cervical spinal nerve 8 - Wikipedia

    en.wikipedia.org/wiki/Cervical_spinal_nerve_8

    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]

  8. Head and neck anatomy - Wikipedia

    en.wikipedia.org/wiki/Head_and_neck_anatomy

    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.

  9. Scalene muscles - Wikipedia

    en.wikipedia.org/wiki/Scalene_muscles

    The anterior scalene muscle (Latin: scalenus anterior), lies deeply at the side of the neck, behind the sternocleidomastoid muscle.It arises from the anterior tubercles of the transverse processes of the third, fourth, fifth, and sixth cervical vertebrae, and descending, almost vertically, is inserted by a narrow, flat tendon into the scalene tubercle on the inner border of the first rib, and ...
