Neck Anatomy Vessels

The vessels of the neck must not only supply and drain cervical structures but also those in the head. The first branch of the thyrocervical trunk is the inferior thyroid artery.

Major Arteries Of The Head And Neck Carotid Teachmeanatomy

The internal carotid arteries pass into the skull inferior to the brain through the left and right carotid foramina.

Neck anatomy vessels. The lymphatic system drains the head and neck of excess interstitial fluid via lymph vessels or capillaries equally into the right lymphatic duct and the thoracic duct. Vessels external carotid branches except post auricular internal anterior jugular vein tributaries. The anterior triangle and the posterior triangle of the neck each of them containing a few subdivisions.

These arise from the brachiocephalic trunk on the right side and directly from the arch of the aorta on the left. Despite being a relatively small region it contains a range of important anatomical features. The neck also contains the thyroid and parathyroid glands the esophagus larynx and trachea and also a number of lymph glands.

Nerves internal external laryngeal nerve to mylohyoid hypoglossal nerve. This vessel supplies the posterior prevertebral muscles. The ascending cervical artery arises from the inferior thyroid artery as it turns medially in the neck.

In the carotid triangle many of the vessels and nerves are relatively superficial and so can be accessed by surgery. Lymph nodes line the cervical spine and neck regions as well as along the face and jaw. The triangles of the neck are the topographic areas of the neck bounded by the neck muscles.

Anatomy of the neck the neck contains a number of overlapping muscles blood vessels nerves and myriad structures all contained in a small space and liable to damage and distress. The left and right carotid arteries each divide in the neck to form the left and right internal carotid as well as the left and right external carotid arteries. One of the functions of the neck is to act as a conduit for nerves and vessels between the head and the trunk.

The largest arteries in the neck are the common carotids. Other jugular chain of lymph nodes. Viscera thyroid larynx submental sub mandibular glands.

The carotid arteries internal jugular vein vagus and hypoglossal nerves are frequent targets of this surgical approach. The tonsils also are lymphatic tissue and help mediate the ingestion of pathogens. The s ternocleidomastoid muscle divides the neck into the two major neck triangles.

It supplies the thyroid gland. The neck is the area between the skull base and the clavicles. They run superiorly before bifurcating at the level of c4.

From this trunk several vessels arise which go on to supply the neck. Instant anatomy is a specialised web site for you to learn all about human anatomy of the body with diagrams podcasts and revision questions.
