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 .
The triangles of the neck describe the divisions created by the major muscles in the region.. The side of the neck presents a somewhat quadrilateral outline, limited, above, by the lower border of the body of the mandible, and an imaginary line extending from the angle of the mandible to the mastoid process; below, by the upper border of the clavicle; in front, by the middle line of the neck ...
Damage results in an inability to shrug the shoulders or raise the arm above the head, particularly due to compromised trapezius muscle innervation. The external jugular vein's superficial location within the posterior triangle also makes it vulnerable to injury.
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 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. 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.
Lymph nodes at Surface: 1. Occipital (retroauricular) 2. Mastoid 3. Superficial Parotid 4. Deep Parotid 5. Preauricular 6. Infraauricular 7. Intraglandular parotid Facial Lymph Nodes: 8. Buccinator 9. Nasolabial 10. Mandibular 11. Anterior Cervical (Superficial jugular) 12. Superficial Cervical (External jugular)
The classification of the cervical lymph nodes is generally attributed to Henri Rouvière in his 1932 publication "Anatomie des Lymphatiques de l'Homme" [6] [7] Rouviere described the cervical lymph nodes as a collar which surrounded the upper aerodigestive tract, consisting of submental, facial, submandibular, parotid, mastoid, occipital and retropharyngeal nodes, together with two chains ...
The superficial cervical lymph nodes are lymph nodes that lie near the surface of the neck.. Some sources state simply that they lie along the external jugular vein, [1] while other sources state that they are only adjacent to the external jugular vein in the posterior triangle, and they are adjacent to the anterior jugular vein in the anterior triangle.
