The Anterior Compartment of the Forearm Flashcards
the muscles of the anterior compartment of the forearm facilitate which movements?
- flexion of the wrist and digits
- pronation of the forearm at the radio-ulnar joint
which superficial flexor forearm muscle is absent in about 20% of people?
palmaris longus
what is the action of the pronator teres?
pronation
apart from flexing the wrist, wich superficial muscle is involved in adduction (ulnar deviation) of the wrist joint?
flexor carpi ulnaris
apart from flexing the wrist, which superficial muscle is involved in abduction (radial deviation) of the wrist joint?
flexor carpi radialis
Three superficial muscles of the anterior compartment of the forearm are supplied by the blank nerve (C5-T1) with the blank nerve (C8-T1) supplying the flexor carpi ulnaris muscle.
Three superficial muscles are supplied by median nerve (C5-T1) with the ulnar nerve (C8-T1) suppling the flexor carpi ulnaris muscle.
what is the anatomical location of the flexor digitorum superficialis (FDS)?
- lies immediately deep to the superficial group of flexors in the forearm and is seen as the only muscle on the intermediate group of the forearm.
the flexor digitorum superficialis has an extensive origin in the forearm, and passes distally down the arm giving rise to how many tendons?
4 tendons
to which digits (fingers) are the tendons of the flexor digitorum superficialis (FDS) attached?
2-5 digits (no thumb)
on which phalanx are the 4 tendons of the flexor digitorum superficialis (FDS) inserted?
middle phalanges of digits 2-5
the flexor digitorum superficialis (FDS) flexes which joints?
- wrist joint
- metacaropophalangeal joints
- proximal interphalangeal joints
can the flexor digitorum superficialis (FDS) act on the distal interphalangeal joint?
no (FDP) acts on distal
