flexor muscles are ___ than extensor muscles
stronger
flexor carpi radialis
O: medial epicondyle
I: palmar base of 2nd and 3rd metacarpal
A: flex carpal joint
flexor carpi ulnaris
O: medial epicondyle and ulnar olecranon
I: accessory carpal bone

nothing to do with digits
superficial digital flexor
O: medial epicondyle
I: palmar base of middle phalanges
A: flex carpal, metacarpophalangeal, and proximal interphalangeal joints

carpal tunnel
canal along palmar carpal fibrocartilage
important structures run through this canal (ex: DDF tendon, median nerve, and vessels)
interossei (interosseus singular)
