25: UE Veins And Lymphatics Flashcards
Vein formed by the subclavian V, along with which other vein
Brachiocephalic V formed by subclavian + internal jugular V
Three veins that join to form the axillary V
- Cephalic V
- Brachial V’s
- Basilic V
What does the cephalic V drain?
Dorsal venous network
Median cubital vein
Communicating branch between cephalic + basilic vein
Where is the median cubital V?
Overlying bicipital aponeurosis in the antecubital region
Most common site of venipuncture + two reasons
Median cubital V:
- Superficial location
- Bicipital aponeurosis protects underlying structures
Brachial V’s
Multiple anastomosing vessels accompanying the brachial A
Four veins drained by the brachial V’s
Ulnar V, radial V, posterior and anterior interosseous V’s
Ulnar and radial V’s
Each are paired, anastomosing veins around thier given Artery
Anterior and posterior interosseous veins
Both paired, anastomosing veins around thier given arteries
What does the basilic vein drain
Dorsal venous network + median antebrachial V
What does the median antebrachial V drain?
Anterior forearm
Perforating veins in the arm
Communicates between superficial and deep veins
Path from lymphatic plexuses in digits and palms -> thoracic duct
Lymphatic plexuses -> superficial lymphatic vessels in UE -> subclavian lymphatic trunk -> thoracic duct
What does the right lymphatic trunk drain -> into what
Subclavian lymphatic trunk + bronchomediastinal trunk -> right lymphatic duct -> brachiocephalic Vein
What two things do the subclavian lymphatic trunks drain into?
Thoracic duct, right lymphatic duct
Cubital LNs
Proximal to medial humeral epicondyle
What do cubital LNs communicate with?
Humeral axillary LNs
Five groups of axillary LNs
- Pectoral axillary LNs
- Subscapular axillary LNs
- Humeral axillary LNs
- Central axillary LNs
- Apical axillary LNs
Pectoral axillary LNs receive lymph from?
Breast, lateral thoracic wall
Subscapular axillary LNs receive lymph from?
Posterior thoracic wall, scapular region
Humeral axillary LNs receive lymph from?
Whole UE (except those accompanying cephalic V)
What three LNs drain into central axillary LNs
Pectoral axillary, subscapular axillary, humeral axillary LNs
What drains into the apical axillary LNs?
Central axillary LNs
Why are axillary LNs important?
Frequent invasion by cancer cells from elsewhere in the body, usually the breasts
Deltopectoral LN location
Near cephalic V at clavipectoral triangle
