6. Forearm flexors which is true
- posterior compartment of arm
- associated with extension of the wrist
- all innervated by ulnar and median nerve C6/7
- supination
- divided into two layers superficial and deep
7. which is false of the superficial flexor group
- flexor carpi ulnaris supplied by the median nerve C6/7
- pronator teres part of group
- all arise from the medial epicondyle
- flexor carpi radialis part of group
8. which is false of the deep and intermediate flexor groups
- flexor pollicis longus to distal phalanx of thumb
- flexor digitorium profundus attaches to terminal phalanx of each finger
- pronator quadratus part of the deep group
- flexor digitorium superficialis deep group attaches to middle phalanx of each finger
- flexor digitorium profundus to digits four and five supplied by ulna nerve
9. which is true of the median nerve in the forearm
- supplies extensors
- inneravtes the posterior compartment
- anterior interosseous arises from it
- passes to the lateral side of the flexor retinaculum
10. radial nerve which is false
- superficial branch is motor
- deep and superficial branches
- superficial branch passes around the radial side of the forearm
- supplies extensors
- vulnerable in shaft of humerus and head of radius
11. which is false of the ulna nerve
- passes down the medial side of the arm
- supplies flexors
- passes posteriorly around the medial epicondyle
- passes under the flexor retinaculum
- two small cutaneous branches plamar and dorsal branch
12. the brachial artery enters the forearm passing through the cubital fossa and dividing into the cephalic and basilic veins
13. which is false of the radial artery
- passes through the lateral aspect of the arm
- lateral to the tendon of the barchiradialis tendon
- originates form the neck of radius
- a branch of brachial
- travels medial to the superficail branch of the radial nerve
14. which is true of the ulna artery
- deep to the flexor retinaculum
- leaves the ACF passing superficial to the pronator teres muscle
- passes down the medial side of the arm
- smaller than the radial
15. which is false of pronation and supination and the bones/ muscles involved
- supination in a flexed elbow allows for easier supination due to biceps
- the articular surface of the radius head slides over the radial notch of the ulna
- held together by the annular ligament, interosssoeus membrane and the articular disc
- involves rotation of the ulna at the elbow and movement of the distal end of the radius over the ulna
- the head of radius spins on the capitulum
16. movements of the forearm and hand which is false
- wrist and finger extension posterior interosseous C7/8
- flexion of the wrist C6/7 median and ulnar nerve
- flexion of fingers FDP/FDS/FPL C7/8 median nerve
- pronation and supination median C6/7, radial C5/C6 and musctaneous C5/C6
17. which is true of the proximal row of carpal bones
- pisiform bone sesimoid bone articulates with lunate
- triquetral four sided bone
- lunate and scaphoid articulate with distal radius
- lunate boat shaped
- scaphoid crescent shaped
18. which is true of the carpal bones distal row
- hamate which has a sesimiod bone shaped like a hook
- trapezium articulates with the thumb
- capitates head articulates with third metatarsal
- trapezoid has three sides
19. which is false of the metacarpals
- consists of a base,shaft, anatomical neck and head
- five bones
- bases articulate with the carpal bones
- heads form the knuckles
- head articulates with the proximal phalanges
20. related to the hand which is false
- the digits are named the thumb, index, middle, ring and little finger
- the fingers and the thumb are broken down into proximal, middle and distal phalanges
- the joint between the metacarpals and the proximal phalanx is called the MCP
- two joints in the fingers the proximal inter phalangeal joint and the distal interphalngeal joint
