upper arm
what arm muscle will allow for elbow flexion, and identify their differences
brachiallis, biceps brachii and brachioradiallis
brachiallis will always flex, bicpes only in supination and brachioradiallis is the parking break, only in neutral position
what muscle(s) can supinate?
supinator
where do the lumbricals attach
the flexor dig profundus
what can be found in the right atrium of the heart
fossa ovalis, pectinate muscles, AV valve (tricuspid)
what goes through the quadrangular space
the axillary n and the posterior humural circumflex artery
what nerve (and its roots) innervate the anterior arm
musculocutaneous nerve (c5-c6)
which muscles make up the anatomical snuff box
the abductor pollicis longus, flexor pollicis longus and flexor pollicis brevis
what is the innervation of the thenar and hypothenar muscles
the median and ulnar nerve
what determines the dominance of the heart
what supplies the PDA (right dominance is right coronary artery, left dominance is left coronary circumflex artery)
which tricep is a 2 joint muscle and where does the muscle attach
the long head of the tricep, infraglenoid tubercle
what are the differences in the teres major and teres minor
teres major is lower scapular nerve, teres minor is the axillary nerve, teres major attaches to the inferior angle, teres minor attaches to lateral border
which nerve enters at the tunnel of guyon (what bones make the tunnel of guyon)
the ulnar nerve, the pisiform and hook of hamate
where does the adductor pollicis muscle insert
the proximal phalanx of the thumb?
which vein accompanies the left anterior descending artery
great cardiac vein
what is the innervation of the subscapularis
the upper and lower sub scapular n
identify muscles that attach to the clavicle
pectoralis major, deltoid, subclavius
which muscles radial deviate and ulnar deviate
radial: extensor carpi radialis, flexor carpi radialis longus and brevis weakly abductor pollicis longus
ulnar: extensor carpi ulnaris, flexor carpi ulnaris
which digits get extra extensors, and what are they called?
extensor indicis and extensor digiti minimi
what can be found in the ventricles
trabeculae carneae, papillary muscles and chordae tendinae
what is a prime protractor of the scapula and what is its innervation
the serratus anterior, the long thoracic nerve
what makes the median cubital vein and why is it clinically relevant
cephalic and basilic, where we get blood drawn
where can the common flexor tendon and common extensor tendon be found
flexor at the medial epicondyle and extensor at the lateral epicondyle
what is the innervation of the lumbricals
half ulnar and have median n
what returns blood directly to the right atrium of the heart
the inferior and superior vena cava and the coronary sinus
name the muscles that are external rotators
infrapsinatus and teres minor
