Apical axillary nodes
Nodi axillares apicales · Vrcholové podpažní uzliny
Lymphatic & immune
Looks like
The highest lymph nodes of the armpit, at its top just under the collarbone, above the pectoralis minor.
What it does
The final filter for all armpit lymph before it drains into the subclavian lymph trunk and the neck veins.
Keeping it well
Cancer here means spread through the whole armpit; surgeons and radiotherapists treat it as a separate level (level III).
