The Neck
摘要
The anatomy of the neck is complex as it represents a transition zone between the head and the thorax. Within the neck region there are many important structures including major vessels of the cardiovascular system (carotid arteries, vertebral arteries, and jugular veins), spinal cord, various peripheral nerves, portions of the gastrointestinal system (pharynx and esophagus), respiratory system (larynx and trachea), and finally the endocrine system (thyroid and parathyroid glands).
