Good things to know. Flashcards
Coracoid process is part of
scapula
tubercles on the humerus are
at the top (proximal) part of the bone
radial groove is for
the radial nerve and the profunda brachia artery
Branches off the POSTERIOR chord
- superior sub scapular N
- thoracodorsal nerve
- inferior sub scapular N
Branches off the MEDIAL chord
- medial pectoral
- medial brachiocutaneous
- medial ante brachialcutaneous
Musculocutaneous innervates:
biceps brachii
coracobrachialis
brachialis
Axillary Innervates
Deltoid
Teres Minor
Median Innervates (7)
Pronator Teres
Flexor Carpi Radialis
Pulmaris Longus
Flexor Digitorum Superficial
Flexor Digitorum Profundus
Flexor Pollicis Longus
Pronator Quadratus
Ulnar Nerve Innervates
Flexor Carpi Ulnaris
Flexor Digitorum Profundus
brachial plexus roots become trunks at
inferior part of neck
lateral border of scalenes
Trunks become divisions at
CERVICO-AXILLARY CANAL
- posterior to clavicle, 1st rib
Divisions become chords at
pectoral minor muscle
Chords become terminal branches at
Axilla
Musculocutaneous Nerve becomes
Lateral cutaneous nerve of the forearm, purely sensory after brachialis
Ulnar nerve courses behind
medial epicondyle of the humerus bone
dorsal scapular artery is a direct branch off of
subclavian artery
Axillary artery is from
lateral border of 1st rib to inferior border of teres major
Brachial artery is from
inferior border of teres major to the distal portion of the cubital fossa
anterior interosseous artery pairs with
median nerve
posterior interosseous artery pairs with
posterior interosseous nerve ((deep branch of the radial nerve))
Ulnar and radial arteries provide
collateral blood supply to hand (palmar arch)
Anterior and posterior interosseous arteries provide
blood flow to anterior and posterior divisions of the interosseous membrane
anterior interosseous artery pairs with
median nerve
basilic vein is on
medial side!
cephalic vein is on
lateral side
basilic vein becomes
axillary vein
cephalic vein empties into
axillary vein
axillary nerve and humerus
axillary nerve winds around surgical neck of humerus
radial nerve and humerus
radial nerve is in radial groove
