Editing Upper limb (section)

=== '''Forearm''' ===

** '''Anterior'''
*** '''Superficial'''
**** All flexors, except for        pronator teres - arise from medial epicondyle of the humerus ('common        flexor origin') and fan out across the volar forearm.
**** All except FCU are        innervated by the median nerve, and half of FDP in the deep        compartment.
**** Pronator teres
***** Arises from CFO, humerus         above (humeral head) and ulna below (ulnar head)
***** Inserts to shaft of         radius
***** Pronates the forearm and         flexes the elbow
***** Median nerve enters the         forearm between the two heads - possible site of entrapment
**** Flexor carpi radialis
***** Arises from CFO and         intermuscular septum
***** Inserts to the base of         the second metatarsal
**** Palmaris longus
***** Arises from CFO and         intermuscular septum
***** Inserts to the flexor         retinaculum
**** Flexor carpi ulnaris
***** Arises from CFO and upper         two-thirds of medial margin of ulna (ulnar head)
***** Inserts to the pisiform         bone
**** Flexor digitorum        superficialis
***** Arises from CFO (upper         head) and shaft of radius (lower head)
***** Inserts to the sides of         the shafts of the middle phalanges of each of the digits

* '''Deep'''
** FDP, FDL and pronator      quadratus
** All arise from shafts of      long bones
** Supplied by median nerve,      except for the ulnar half of FDP

* '''Posterior'''
** '''Superficial'''
*** Extensors/supinators -       arise from the lateral epicondyle of the humerus and extends towards the       dorsum of the wrist
**** Extensor carpi ulnaris
**** Extensor digitorum
**** Extensor digiti minimi
**** Extensor carpi radialis        longus and brevis
**** Brachioradialis
*** Supplied by radial nerve
***

* '''Deep'''
** Supinator, abductor pollicis      longus, extensor pollicis longus, extensor pollicis brevis, extensor      indices
** Arise from posterior      surfaces of forearm bones and interosseous membrane
** Supplied by posterior      interosseous nerve (branch of radial)
