Thoracic outlet syndrome Sympathetic nervous system (diagram) The sympathetic nervous system is part of the autonomic nervous system, along with its counterpart, parasympathetic nervous system.. The inner surface of the concha is covered by a mucous membrane that contains large vascular spaces that can change in size in order to control the width of the nasal cavity. The vertebral column, also known as the backbone or spine, is part of the axial skeleton.The vertebral column is the defining characteristic of a vertebrate in which the notochord (a flexible rod of uniform composition) found in all chordates has been replaced by a segmented series of bone: vertebrae separated by intervertebral discs. In T1, it resembles the cervical vertebrae; they are similar to the lumbar vertebrae in the lower thoracic vertebrae. Individual vertebrae are named according to Thorax Open Access. It starts just below the skull and ends just above the Thoracic cage The hyoid bone (lingual bone or tongue-bone) (/ h a d /) is a horseshoe-shaped bone situated in the anterior midline of the neck between the chin and the thyroid cartilage.At rest, it lies between the base of the mandible and the third cervical vertebra.. Operative Neurosurgery is the resource for cutting-edge material on operative practice. The spinal cord is a long bundle of nerves and cells that carries signals between the brain and body. Their role is to protect the surface of epithelium, lubricate it, and catch harmful particles.
