Origin
The origin of the flexor carpi radialis & ulnaris, palmaris longus, flexor digtorum superficial & profundus is the
What is the medial epicondyle
True or False: The dorsal interossei is found on the base of proximal phalanx of fingers 2,4, & 5, while the palmar interossei are only found on fingers 2, 3, & 4.
What is false
Explanation: The palmar interossei adducts the index, ring, and pinky finger towards the middle so it would not involve the 3rd finger
True or False: The flexor digitorum superficialis, palmaris longus, flexor digitorum profundus, and extensor digitorum attach to phalanges 2-5
What is false
Explanation: Palmaris Longus attaches to the flexor reticulum and palmar aponeurosis
The flexor carpi radialis is the primary mover for
What is radial deviation
Which phalanx is not present in the thumb?
What is the middle phalanx
This muscle, responsible for adducting the thumb, originates from the base of the 2nd and 3rd metacarpals and the capitate
What is adductor pollicis
This muscle, responsible for flexing the thumb, is inserted at the base of the distal phalanx of the thumb
What is flexor pollicis longus
The extensor carpi ulnaris, originating from the lateral epicondyle inserts at the base of
What is metacarpal 5
True or False: The abductor pollicis longus and brevis and extensor pollicis longus and brevis are the main contributors to thumb CMC Radial Abduction
What is true
The extensor pollicis longus and brevis are supplied by
what is the radial nerve
The abductor pollicis brevis, flexor pollicis brevis & opponens pollicis all originate at one common carpal bone which is the
what is trapezium
The muscles in the hypothenar group of the hand are all inserted onto
What is Metacarpal 5
Explanation: the hypothenar group consists of the abductor, flexor, and opponens digit minimi which are all mucles of the metacarpal 5 AKA pinky
The muscles of the thenar group all attach to metacarpal ___ of the finger also known as the _______
What is 1 and thumb
Explanation: the thenar group is responsible for controlling the thumb. Think - Thenar - Thumb
This muscle is the prime mover for wrist flexion, especially when combined with others, and is located deep to the flexor carpi radialis
what is palmaris longus
True or False: The lumbricals, palmar and dorsal interossei muscles all extend the MCP joints and flex the proximal and distal interphalangeal joints
What is false
Name one extensor muscle in the posterior forearm that attaches to the lateral epicondyle of the humerus
What is extensor carpi radialis longus, extensor carpi brevis, extensor carpi ulnaris or extensor digitorum
The Extensor Carpi Radialis Longus & Extensor Carpi Brevis attach to metacarpals
What is Metacarpals 2 (Longus) and 3 (Brevis)
This muscle is responsible for extending the thumb and inserts at the base of the proximal and distal phalanx of the thumb
What is extensor pollicis longus and brevis
This muscle acts as the prime mover for finger extension, and it originates from the lateral epicondyle of the humerus
What is the extensor digitorum?
These nerves supply the lumbricals
What is median and ulnar nerve
This muscle, responsible for flexing the thumb, originates from the anterior surface of the radius and the interosseous membrane
What is flexor pollicis longus
This muscle attaches to the pisiform, hamate, & 5th metacarpal
What is Flexor Carpi Ulnaris
This muscle, responsible for extending and adducting the 2nd finger, originates from the distal ulna and attaches to the proximal phalanx of the 2nd finger
what is extensor indicis
The primary muscles for ulnar deviation for an activity like using a hammer are
What is extensor carpi ulnaris and flexor carpi ulnaris
The abductor digiti minimi of the hypothenar group abducts the MCP joint and originates at the carpal bone
what is pisiform
