Presentation transcript:

Lymphatic's of the Head & Neck By Dr.Musaed Alfayez

Lymph nodes of head & Neck are divided into: A- Several regional groups B- One terminal group. Regional group of lymph nodes: 1- Occipital. 2- Mastoid or retroauricular 3- Parotid or preauricular 4- Buccal or facial. 5- Submandibular. 6- Submental. 7- Anterior cervical 8- Superficial cervical 9- Laryngeal. 10-Tracheal. 11- Retropharyngeal.

Its efferent pass to Submandibular & deep cervical nodes. Submental Group: Lies in submental triangle It drains: Tip of tongue. Floor of mouth below the tip of the tongue Central incisors & associated gums. Central part of lower lip. Skin of the chin. Its efferent pass to Submandibular & deep cervical nodes.

The terminal group of lymph nodes ( deep cervical group) receives all the lymph vessels of the head & neck either directly or indirectly via one of the regional group They are closely related to carotid sheath, Particularly to internal jagular vein. Two of these nodes are chiefly clinically important: 1-Jugulodigastric node. 2-Jugulo-omohyoid node.
