where does the common flexor forearm tendon attach?
the medial epicondlye and supracondylar ridge
what muscles are in the middle layer of the forearm flexor compartment?
the flexor digitorum superficialis
what muscles are in the deep layer of the forearm flexor compartment?
the flexor pollicis longs, flexor digitorum produndus, and pronator quadratus
which muscles are in the superficial layer of the extensor compartment of the forearm?
the brachioradialis, extensor carpi radialis longus, the extensor carpi radialis brevis, the extensor digitorum, the extensor digiti minimi and the extensor carpi ulnaris
which muscles are in the deep layer of the extensor compartment of the forearm extensor compartment?
the supinator, the extensor indicis, the extensor pollicis brevis, the extensor pollicis longus, and the abductor pollicis longus
is the extensor compartment of the forearm dorsal or ventral?
dorsal.
what does the common interosseus artery branch into?
the anterior and posterior interosseus branches
which artery passes between the radius and the ulna?
the posterior interosseus artery.
what does the medial antebrachial cutaneous nerve come from?
the medial cord
what does the lateral antebrachial cutaneous nerve come from?
the musculocutaneous nerve
where does the posterior antebrachial cutaneous nerve come from?
the radial nerve
which nerve is responsible for sensatioon the lateral half of the forearm?
the lateral cutaneous nerve (which comes from the musculocutaneous nerve)
which nerve innervates most of the flexor forearm muscles?
the median nerve
does the ulnar nerve have any branches in the forearm?
no
what does the ulnar nerve innervate?
the ventral and dorsal aspect of the ulnar one and half digits (cutaneous)
does the ulnar nerve go through the carpal tunnel?
no
which nerve innervates all of the extensor muscles?
the radial nerve
what innervates the supinator and then pierces it?
the radial nerve
what innervates the long abductor of the thumb?
the posterior interosseus nerve
which nerve is responsible for cutaneous innervation of the radial dorsum of the hand?
the superficial radial nerve
what travels through the carpal tunnel?
the median nerve, the flexor pollicis longus tendon, the flexor digitorum superficials tendons, and the flexor digitorum profundus tendons
what is perceived in carpal tunnel syndrome?
sensations related to the pinching of the median nerve
what kind of joint exists between the radius and ulna?
a syndesmoses
what is the name of the ligament that holds the radius to the ulna?
the annular ligament
does the ulna articulate with the carpals directly?
no, there's an articular disc between them.
what is compartment syndrome?
when there is bleeding into one of the forearm compartments, creating pressure. this can cause the contents of the compartment to die.
which extensor compartment muscle helps flexion at the elbow joint?
the brachioradialis
what is the extensor hood an extension of?
the extensor digitorum
what structures form the borders of the anatomical snuffbox?
the tendons of the abductor pollicis longus and extensor pollicis brevis (laterally) and the tendon of the extensor pollicis longus (medially)
what rests in the base of the anatomical snuffbox?
the radial artery
waht does the brachial artery branch into?
the radial and ulnar arteries
what is a vena commitans?
two veins sandwiching an artery; functions for countercurrent heat exchange and blood pumping
do the posterior interosseus nerve and artery travel together?
no
what structures do NOT pass through the carpal tunnel but still go to the hand?
the ulnar nerve and artery, and the radial artery
what forms the roof of the carpal tunnel?
the flexor retinaculum
