Super: terres major
Lateral”: humerus
inferior medial: long head of triceps

Question 9

Describe lymphatic drainage of the upper limb

Answer 9

Most drainage from the palm passes to the dorsum of the hand. Most superficial lymphatics accompanying the cephalic vein enter the apical axillary lymph nodes. The superficial lymphatics accompanying the basilic vein enter the cubital lymph nodes and then drain into the lateral axillary lymph nodes. The axillary lymph nodes drain into the subclavian lymphatic trunk
