posterior forearm

Question 1

what two muscles attach to the lateral supracondylar ridge in the posterior forearm

Answer 1

two of the muscles of the superficial posterior forearm - the brachioradials and the extensor carpi radialis longus

Question 2

what muscles of the posterior forearm attach to the lateral epicondyle

Answer 2

extensor carpi radialis brevis, extensor digitorum, extensor digiti minimi, extensor carpi ulnaris, and the anconeus

Question 3

what are the muscles of the deep posterior forearm

Answer 3

the supinator, abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus and the extensor indicis

Question 4

what does the anconeus muscle do

Answer 4

it prevents the capsule of the elbow from getting trapped when we are doing extension of the elbow. - also can be an elbow extendor

Question 5

distal connection points and thus function of the ECU, ECRL, ECRB

Answer 5

these all attach to the metacarpals of the hand. this means they will be doing wrist extension

Question 6

attachments of the brachioradialis and function

Answer 6

the lateral supracondylar ridge and the radial styloid process, thus this does elbow flexion

Question 7

distal attachment of the extensor digitorum and function

Answer 7

this makes the extensor hood on the 2-5th fingers, thus extension of the fingers and maybe wrist extension too?
