Lymph Nodes Flashcards
What are the superficial cervical lymph nodes
Submental
Submandibular
Pre-auricular
Post-auricular
Occipital
Superficial cervical
Posterior cervical
Anterior cervical
What area do the submental nodes drain
Central lower lip, flood of mouth and apex of tongue
What area do the submandibular nodes drain
Cheeks, lateral aspects of the nose, upper lip, lateral lower lip, gums and anterior tongue
What area do pre-auricular nodes drain
Superficial areas of the face and temporal region, and eye tissue
What area do post-auricular nodes drain
Posterior neck, upper ear and back of external auditory meatus (ear canal)
What area do occipital nodes drain
Occipital region of the scalp
What area do posterior cervical nodes drain
Superficial areas of the neck
What area do anterior cervical nodes drain
Superifical surface of anterior neck
Where are deep cervical lymph nodes found
THey are found within the neck, deep to the investing layer of cervical fascia
When can superficial and deep lymph nodes be palpatede
Superifical nodes are readily palpable - easily palpated when enlarged though sometimes can be palpated in health
Deep nodes are not readily palpable unless enlarged
Name some deep cervical lymph nodes
Jugulo-digastric
Jugulo-omohyoid
Supraclavicular
What area do jugulo-digastric nodes drain
Palatine tonsils -> swollen in tonsilits
Also drain oral cavity and tongue
What area do jugulo-omohyoid nodes drain
Posterior tongue, oral cavity, trachea, oesophagus and thyroid gland
What area do supraclavicular nodes drain
Receive lymph from the neck and from the thorax and abdomen -> become enlarged with pathology affecting thorax and/or abdomen
What collection of lymphoid tissue is found surrounding the upper aerodigestive tract
