describe the anterior capsule

Answer 9

broad and thin
attach above medial epicondyle and above the coronoid and radial fossa
attaches below to annular ligament

articular supply (segmental, Peripheral)

Answer 13

Segmental C5-T1
Peripheral
median nerve branches- anterior capsule
ulnar nerve branches supply UCL and posteromedial capsule
