Lymphatics of the head and neck

Lymphatics of the Head and Neck refers to the lymphatic system structures located in the head and neck region. These structures play a crucial role in the body's immune response and fluid balance. They include lymph nodes, lymphatic vessels, and lymphatic tissues.

Anatomy

The lymphatics of the head and neck consist of a network of lymphatic vessels and nodes. The lymphatic vessels are responsible for transporting lymph, a clear fluid containing white blood cells, throughout the body. The lymph nodes are small, bean-shaped structures that produce and store cells that fight infection and disease.

The lymphatic system in the head and neck region is divided into superficial and deep systems. The superficial system drains the scalp, face, and some parts of the neck. The deep system drains the pharynx, palate, nasal cavity, and the rest of the neck.

Function

The primary function of the lymphatics of the head and neck is to protect the body from infection. They do this by producing and transporting lymphocytes, a type of white blood cell, to areas of the body where they are needed. They also remove excess fluid, waste, and toxins from the body tissues.

Clinical Significance

The lymphatics of the head and neck are often involved in various diseases and conditions. For example, lymphadenopathy (swelling of the lymph nodes) in this region can be a sign of infection, autoimmune disease, or cancer. Lymphedema, a condition characterized by swelling due to a blockage in the lymphatic system, can also occur in the head and neck region.
