What are the 3 nodes that drain into the central node?
and from where do they receive? |
1. pectoral=ant thoracic wall and breasts
2. humeral= upper limb (except what goes through cephalic) 3. subscapular= post thoracic & scapular region |
|
|
if subclavian lymphatic trunk goes L?
goes R? |
R= joins with jugular and subclavian to make R. lymphatic duct

|
|
(injury) Prefixed brachial plexus
|
C4-C8 ventral rami form roots
|
|
|
(injury) Postfixed brachial plexus

|
(injury) Surgical procedures to axilla:
|
-axillary lymph node disseciton
-mastectomy -risk of damage to long thoracic & thoracodorsal nerves |
|
|
(injury) Erb-Duchenne Palsy- C5-6 roots/superior trunk
|
mechanism: excessive increase in angle bw neck and shoulder
(landing on shoulder/neck, newborn delivery, carrying heavy loads "backpackers palsy") -paralysis of shoulder and arm muscles -loss of lateral sensation -"waiter's tip" |
|
|
(injury) klumpke paralysis- C8-T1 roots/inferior trunk
|
mechanism: sudden forceful superior pull on the arm
(grabbing something to break your fall, newborn deliver) -paralysis of intrinsic (short) hand muscles -loss of medial sensation (hand, forearm, arm) -claw hand deformity (hard to make a fist) |
