Q

what is the intermediate muscle of the anterior forearm

A

flexor digitorum superficialis - ulnar head and humeral head

22
Q

what are the 3 deep muscles of the anterior forearm

A

-flexor digitorum profundus, flexor pollicis longus, pronator quadratus

23
Q

what are the 6 muscles of the superficial layer of the posterior forearm (radialis group)

A

-brachioradialis
- extensor carpi radialis longus
-extensor carpi radialis brevis
-extensor capri ulnaris
-extensor digit minimi
-extensor digitorum

24
Q

what are the 5 deep muscles of the posterior forearm

A

-supinator
-abductor pollicis longus
-extensor pollicis longus
-extensor pollicis brevis
- extensor indicis

25
where do most of the superficial extensors attach to
lateral epicondyle of humerus
26
what does brachioradialis do
flexes the elbow joint
27
what are all of the muscles of the posterior forearm innervated by
the radial nerve via the deep branch of the radial nerve or posterior interosseous nerve
28
where is the superficial branch of the radial nerve located and what type of innervation does it supply
lateral, runs beneath brachioradialis -cutaneous only, no motor branches
29
where is the deep branch of the radial nerve located and what does it become
posterior, becomes posterior interosseous nerve
30
what does the deep branch of the radial nerve continue as
the posterior interosseous nerve
31
what do the tendons of extensor digitorum form
a dorsal expansion over the metacarpophalangeal and interphalangeal joints called the extensor expansion and extensor hood
32
what happens to the extensor hood as the extensor digitorum contracts
the extensor digitorum pulls on the extensor expansion (extensor hood), which causes the IP joints to extend
33
what else attaches to the expansion at the hood and help to extend the IP joints
the lumbricals
34
what are the "outcropping" muscles/ the muscles that form the anatomical snuff box
-abductor pollicis longus -extensor pollicis longus -extensor pollicis brevis
35
what are the deep extensors of the posterior forearm innervated by
deep branch of the radial nerve of the posterior interosseous nerve
36
what are the anatomical relationships from lateral to medial of the radial artery, ulnar artery and nerve, median nerve, and superficial branch of the radial nerve
-superficial branch of the radial nerve - radial artery -median nerve -ulnar artery -ulnar nerve
37
where is the ulnar nerve located in relation to the medial epicondyle
posterior
38
where does the ulnar nerve run
along the medial forearm under the flexor carpi ulnaris
39
what does the ulnar nerve go through
guyon's cancl lateral to the pisiform bone
40
what does the ulnar nerve supply as it enters the hand
most of the intrinsic muscles of the hand
41
what is the spatial relationship between the ulnar nerve and ulnar artery
they run together but the nerve is medial
42
what is the spatial relationship between the ulnar artery and flexor carpi ulnaris
located under flexor carpi ulnaris or just lateral to it
43
what is the spatial relationship between the ulnar artery and nerve to psiform bone and guyon's canal
lateral
44
what is the median nerves spatial relationship to pronator teres
runs through it
45
what is the median nerves spatial relationship to flexor digitorum superficialis
deep to it, runs between FD superficialis and FD profundus
46
what is the median nerves spatial relationship to flexor retinaculum
deep to it through carpal tunnel
47
what is the ulnar artery's spatial relationship to flexor carpi ulnaris
located under flexor carpi ulnaris or just lateral to it
48
what is the ulnar artery and ulnar nerve's relationship to the pisiform bone and guyons canal
lateral
49
what is the radial artery's relationship to the superficial branch of the radial nerve
artery is medial
50
what is the radial artery's relationship to brachioradialis
under brachioradialis or just medial to it
51
what is the relationship between anterior interosseous nerve and anterior interosseous artery to the pronator quadratus muscle
the nerve and artery run deep (posterior) to the muscle
