'''''Flexor carpi radialis'''''

'''''Flexor carpi radialis'''''

:The most medial, inserts on the proximal part of metacarpal II (medial splint)

:The most medial, inserts on the proximal part of the second metacarpal(medial splint)bone

'''''Flexor carpi ulnaris'''''  

'''''Flexor carpi ulnaris'''''  

:The most caudolateral

:The most caudolateral

:'''Insertion''': Accessory carpal bone and the fourth metacarpal (lateral splint) bone.

:'''Insertion''': Accessory carpal bone and the fourth metacarpal (lateral splint) bone.

:'''Action''': Flexes the carpus rather than extends it due to its insertion caudal to the carpal joint axis.

'''''Superficial Digital Flexor'''''

'''''Superficial Digital Flexor'''''

:Inserts on the proximal extremity of middle phalanx and the distal extremity of proximal phalanx.

: Overlies, and is partially fused with, the ''deep digital flexor'' muscle.

:'''Insertion''': Proximal extremity of middle phalanx and the distal extremity of proximal phalanx via the superficial digital flexor tendon.

'''''Deep Digital Flexor'''''

'''''Deep Digital Flexor'''''

:Passes through the carpal canal before branching and continues to palmar distal phalanx.

:Deep to the ''superficial digital flexor'' muscle and flexor muscles of the carpus. Passes through the carpal canal before branching and continues to insert on the palmar distal phalanx via the deep digital flexor tendon.
