FOREARM - FLEXOR Flashcards
includes the muscles origin, insertion, innervation and action of the muscles in the forearm
What is the origin of the Pronator Quadratus?
Anterior surface of the ulna
The Pronator Quadratus is a deep muscle in the forearm involved in forearm pronation.
What is the insertion point of the Flexor Pollicis Longus?
Base of the distal phalanx of the thumb
This muscle flexes the phalanges of the thumb.
Which nerve innervates the Flexor Digitorum Profundus?
Ulnar nerve, anterior interosseous nerve
This muscle is responsible for flexion of the distal phalanges at the interphalangeal joints.
What is the function of the Flexor Digitorum Superficialis?
Flexion of middle phalanges at proximal interphalangeal joints and flexion of the proximal phalanges at the metacarpophalangeal joints of the middle four digits
The Flexor Digitorum Superficialis is crucial for finger flexion.
What is the origin of the Flexor Carpi Ulnaris?
Humeral head (medial epicondyle of humerus), ulnar head (olecranon and posterior border of the ulna)
This muscle aids in wrist flexion and adduction.
What is the insertion point of the Flexor Carpi Radialis?
Bases of 2nd metacarpal bone
It helps in flexion and abduction of the hand at the wrist joint.
Which nerve innervates the Palmaris Longus?
Median nerve
The Palmaris Longus is involved in the flexion of the hand at the wrist joint.
What is the function of the Pronator Teres?
Pronation of forearm, flexion of elbow
This muscle assists in both pronation and flexion of the forearm.
Fill in the blank: The mnemonic for remembering the forearm flexors is _______.
Pass/Fail, Pass/Fail, Fail
This mnemonic helps recall the names of the forearm flexor muscles.
What is the function of the Flexor Carpi Ulnaris?
Flexion and adduction of the hand at the wrist
This muscle plays a key role in wrist movements.
What is the origin of the Flexor Digitorum Superficialis?
Medial epicondyle of the humerus and coronoid process of the ulna and superior half of anterior border
This muscle is involved in flexing the middle phalanges.
