The occipital lymph nodes, one to three in number, are located on the back of the head close to the margin of the trapezius and resting on the insertion of the semispinalis capitis. Their afferent vessels drain the occipital region of the scalp , while their efferents pass to the superior deep cervical glands .

Buccinator 9. Nasolabial 10. Mandibular 11. Anterior Cervical (Superficial jugular) 12. Superficial Cervical (External jugular)
Lymph nodes of the lungs: The lymph is drained from the lung tissue through subsegmental, segmental, lobar and interlobar lymph nodes to the hilar lymph nodes, which are located around the hilum (the pedicle, which attaches the lung to the mediastinal structures, containing the pulmonary artery, the pulmonary veins, the main bronchus for each side, some vegetative nerves and the lymphatics) of ...
The mastoid lymph nodes (retroauricular lymph nodes or posterior auricular glands) are a small group of lymph nodes, usually two in number, located just beneath the ear, on the mastoid insertion of the sternocleidomastoideus muscle, beneath the posterior auricular muscle.
Apex: Union of the sternocleidomastoid and the trapezius muscles at the superior nuchal line of the occipital bone. Anteriorly: Posterior border of the sternocleidomastoideus. Posteriorly: Anterior border of the trapezius. Inferiorly: Middle one third of the clavicle. Roof: Investing layer of the deep cervical fascia. Floor: (From superior to ...
1: Submental lymph nodes 2: Submandibular lymph nodes 3: Supraclavicular lymph nodes 4: Retropharyngeal lymph nodes 5: Buccinator lymph node 6: Superficial cervical lymph nodes 7: Jugular lymph nodes 8: Parotid lymph nodes 9: Retroauricular lymph nodes and occipital lymph nodes
Lymph nodes line the cervical spine and neck regions as well as along the face and jaw. The tonsils also are lymphatic tissue and help mediate the ingestion of pathogens. Tonsils in humans include, from superior to inferior: nasopharyngeal tonsils (also known as adenoids ), palatine tonsils , and lingual tonsils .
The occipital triangle, the larger division of the posterior triangle, is bounded, in front, by the Sternocleidomastoideus; behind, by the Trapezius; below, by the Omohyoideus. Its floor is formed from above downward by the Splenius capitis , Levator scapulæ , and the Scalenus medius and posterior.
