Base of distal phalange 2-5, palmar surface
Distal 2-5
Action of flexor digitorum profundus
Flexion of MCP and DIP of 2-5th, may flexion of the wrist
Origin of flexor pollicis longus
The anterior surface of the radius, deep to flexors, interosseous membrane
Insertion of flexor pollicis longus
The base of the distal phalange thumb
Action of flexor pollicis longus
Flexion of IP of thumb assists flexion thumb MCP and CMC
Origin of pronator quadratus
