By Tyler Woodward

The neck is one of the most complex parts of the human body. The neck houses many important structures that are crucial to the survival of the organism such as the thyroid gland, spinal cord, and passage to the lungs and stomach.

General Function Of The Neck:

Function Of The Work

Technically, the neck is the area that lies above the collar bone and below the lower jaw. Starting from the outside going inward we have the skin. The skin has nerve endings that originate from the 2nd-4th cervical nerves.

Beneath the skin is a layer of subcutaneous fat and connective tissue that is known as the superficial fascia. This is the layer in which many blood vessels pass through, like the external jugular vein and tributaries. The veins are responsible for getting blood from the face, scalp, and neck back to the heart and lungs to off load byproducts and get more oxygen.

Next to the external jugular vein are the superficial lymph nodes. These lymph nodes are mostly responsible for helping to keep the body free of infection. Lymph nodes mainly act as a filter for lymph fluid which contains white blood cells known as lymphocytes. Also found in this subcutaneous layer is the platysma muscle that helps to depress the lower jaw.

Structure Of The Inside Of The Neck:

Structure Of The Neck

The neck, being one of the most complex parts of the human anatomical system, is made up of various muscles, bones, passageways, and connective tissues. The main parts of the neck that are worth noting are:

  • Infrahyoid Muscles - These muscles are involved in swallowing, talking, and moving the larynx.
  • Platysma Muscle - Muscle at the front of the neck that plays a part in facial expressions
  • Sternocleidomastoid - Side muscle of the neck that plays a part in the rotation of the head and flexion of the neck.
  • Trapezius Muscle - Muscle of the back of the neck and upper back that shrugs the shoulders.
  • Deep Cervical Muscles - Extend the Head
  • Trachea - Known as the windpipe
  • Thyroid Gland - Endocrine gland that modulates metabolism and growth through the production of various hormones.
  • Oesophagus - Passage that leads to the stomach
  • Spinal Cord - Part of the nervous system that carries information to and from the brain
  • Vagus Nerve - The tenth cranial nerve that communicates with the heart, viscera, and blood vessels in the body.
  • Cervical Vertebra - Seven vertebra that are located in the neck.
  • Carotid Artery - Main blood supplier of head and neck
  • Internal Jugular Vein - Pathway for most of the drainage of blood from the head and neck.
