name the three branches of the artery that run along the brachial plexus
What is the subclavian artery, axillary artery, and brachial artery
this nerve innervates the anterior upper arm muscles
What is musculocutaneous nerve
the subscapularis inserts here
these structures border the quadrangular space
What are the long head of triceps, neck of humerus, teres minor, and teres major
these structures make up the anatomical "snuff box"
What are tendons of the abductor pollicis longus, extensor pollicis brevis, extensor pollicis longus, scaphoid
this artery supplies the anterior and posterior shoulder as well as pectoralis major and minor
What is the Thoracoacromial artery
this is the area of the palmar and dorsal hand innervated by the median nerve
Palmar: digits 1, 2, 3, and half of 4
Dorsal: tips of digits 1, 2, 3, and half of 4
these make up the SITS mneumonic
What is the Supraspinatus, Infraspinatus, Teres minor, and Subscapularis (Bonus: where are these insertions?)
these structures border the triangular space
long head of triceps, teres minor, teres major
this structure has a compartment in the wrist outside of the carpal tunnel all to itself
this sensory nerve is a branch of the musculocutaneous never
lateral cutaneous of forearm
the latissimus dorsi muscle is innervated by this nerve
thoracodorsal nerve (Bonus: name the cord this nerve branches off from)
this nerve innervates the serratus anterior, what roots does it branch off from?
the long thoracic nerve, roots of C5, C6, C7
these structures border the triangular interval
long head of triceps, lateral head of triceps, teres major
this groove runs between the hook of the hamate and the pisiform, and holds the ulnar nerve and artery
What is Guyon's canal (nerve and artery can be compressed here)
these muscles are the thenar eminence
What is abductor pollicis brevis, flexor pollicis brevis, opponens pollicis
these muscles are innervated by the suprascapular nerve
What is the supraspinatus and infraspinatus
this ligament separates suprascapular nerve and artery. ___goes over, and ___ goes under
Superior transverse scapular ligament )over the suprascapular notch) Suprascapular artery goes over ligament, suprascapular nerve goes under the ligament (army goes over, navy goes under)
these structures lie within the quadrangular space
axillary nerve, posterior humeral circumflex artery
this triangular space lies in the anterior elbow and contains what 3 important structures
What is the cubital fossa, biceps tendon, brachial artery, median nerve (TAN - tendon, artery, nerve), *median cubital vein (blood draws)
these muscles are the hypothenar eminence
palmaris brevis, abductor digiti minimi, flexor digiti minimi brevis, opponens digiti minimi
the lower subscapular nerve innervates these two muscles
these 3 muscles are innervated by the dorsal scapular nerve
Levator scapulae, rhomboid major and rhomboid minor (Bonus: what root does this come off of?)
this structure lies within the triangular space
scapular circumflex artery
these structures lie within the triangular interval
radial nerve and profunda brachii artery
