![]() They bound the two major neck triangles anterior and posterior. Muscles of the neck attach to the skull, hyoid bone, clavicles and the sternum. Each carotid sheath contains the vagus nerve, common carotid artery and internal jugular vein.īesides the listed structures, the neck contains cervical lymph nodes which surround the blood vessels. Vascular compartment is paired and consists of the two carotid sheaths found on each side of the trachea.Visceral compartment accommodates the trachea, larynx, pharynx, thyroid and parathyroid glands.As the vertebrae bound the spinal canal, the cervical portion of the spinal cord is also found within the neck. ![]() The alignment of the vertebrae defines the shape of the human neck. Vertebral compartment contains the cervical vertebrae with cartilaginous discs between each vertebral body.The neck structures are distributed within four compartments: Structure Muscles in the human neck Compartments 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). In anatomy, the neck is also called by its Latin names, cervix or collum, although when used alone, in context, the word cervix more often refers to the uterine cervix, the neck of the uterus. Muscles of the neck are described separately from the compartments. Within these compartments, the neck houses the cervical vertebrae and cervical part of the spinal cord, upper parts of the respiratory and digestive tracts, endocrine glands, nerves, arteries and veins. The structures of the human neck are anatomically grouped into four compartments vertebral, visceral and two vascular compartments. In addition, the neck is highly flexible and allows the head to turn and flex in all directions. The neck supports the weight of the head and protects the nerves that carry sensory and motor information from the brain down to the rest of the body. The neck is the part of the body on many vertebrates that connects the head with the torso.
