Anatomical terminology [ edit on Wikidata]

The occipital lymph nodes are a group of 1-3 superficial lymph nodes of the head situated in the occipital region that drain part of the scalp of the occiput. ^[1]

They are situated at the margin of the trapezius and resting on the insertion of the semispinalis capitis .^{[ citation needed ]}

Territory

Afferents

Afferents of occipital lymph nodes contribute to the drainage of the occipital region of the scalp (this region is also drained by a lymphatic vessel which passes along the posterior border of the sternocleidomastoid muscle to drain directly into the inferior deep cervical lymph nodes). ^[2]

Efferents

Their efferents in turn drain into the superior deep cervical glands. ^{[1] [2]}

Clinical examination

During physical examination, these nodes are examined by having the patient bend their head forward and bilaterally palpating the base of the side of the head. ^[1]
