Where does the Jugulodigastric lymph node drain?
The jugulodigastric lymph nodes, also known as subdigastric lymph nodes, are deep cervical nodes located below the posterior belly of the digastric muscle and anterior to the internal jugular vein. They are located in neck node level IIa and receive lymphatic drainage from the tonsils, pharynx, oral cavity and face.
What area does the submandibular lymph node drain?
The afferents of the submandibular glands drain the medial canthus, the cheek, the side of the nose, the upper lip, the lateral part of the lower lip, the gums, and the anterior part of the margin of the tongue. Efferent lymph vessels from the facial and submental lymph nodes also enter the submandibular glands.
Where are the main 3 sites for lymph nodes?
There are three superficial regions on each side of the body where lymph nodes tend to cluster. These areas are the inguinal nodes in the groin, the axillary nodes in the armpit, and the cervical nodes in the neck.
What do the Retroauricular lymph nodes drain?
These nodal groups drain the efferent lymphatics from the occipital, retro-auricular, occipital, and parietal scalp nodes. It receives direct drainage from the skin of the lateral and posterior neck and shoulder, the nasopharynx, oropharynx, and thyroid gland.
What lymph node drains the ear?
The preauricular lymph nodes are the ones located just in front of your ears. They drain lymph fluid from the eyes, cheeks, and the scalp near your temples.
Where do axillary nodes drain?
[2] The axillary lymph nodes arrange into five groups based on their anatomical relations. Collectively, they drain the wall of the thorax, breast, arm, and upper abdominal wall above the umbilicus.
Where are the main clusters of lymph nodes found?
There are about 600 lymph nodes spread throughout the body. 23 The major clusters of lymph nodes are in the armpit, groin, and neck.
Where does lymphatic drainage of the head and neck take place?
The superficial vessels drain lymph from the scalp, face and neck into the superficial ring of lymph nodes at the junction of the neck and head. The deep lymphatic vessels of the head and neck arise from the deep cervical lymph nodes. They converge to form the left and right jugular lymphatic trunks:
How is retroauricular node bearing tissue dissected?
The retroauricular node-bearing tissue is dissected away from the mastoid and over the superior portion of the SCM muscle. The posterior aspect of the SCM muscle is identified and defined. The spinal accessory nerve is identified exiting the SCM muscle approximately 1 cm superior to Erb’s point.
Where are lymph nodes located in radical neck dissection?
Located on or behind the mastoid process These lymph nodes are not typically included in the standard radical or modified radical neck dissection Suboccipital and retroauricular lymph nodes drain primarily into the spinal accessory lymph node chain and secondarily into Level II
