Upper limb part 2 Flashcards
axillary artery
from subclavian artery that enters axilla that becomes axillary artery
axillary artery gives rise to
-thoracoacromial artery
-lateral thoracic artery
-subscapular artery
-also continues into brachial artery
brachial artery give rise to
-posterior circumflex artery
-deep artery of the arm
-ulnar collateral arteries
-interosseous arteries
-radial artery
-ulnar artery
digital arteries
-form in palm from radial and ulnar arteries from superficial and deep palmar arches
superficial veins of upper limb
-basilic vein
-cephalic vein (connected to median cubital vein)
-median vein of forearm
where do you draw blood from
median cubital vein
basilic vein anastomoses with
brachial vein to form axillary vein
cephalic vein anastomoses with
axillary vein
axillary vein becomes the
subclavian vein
deep vein of upper limb
-digital veins
-deep and superficial palmar arches
-ulnar vein
-radial vein
-brachial vein
brachial plexus pneumonic

-roots
-trunks
-divisions
-cords
-nerves
anterior rami in brachial plexus
C5-T1
Roots of brachial plexus
C5-T1
3 trunks of brachial plexus
-superior trunk
-middle trunk
-inferior trunk
divisions of brachial plexus
3 anterior and 3 posterior divisions, 1 each from superior, middle and inferior trunk
Cords of brachial plexus
Lateral medial and posterior
nerves of brachial plexus
-musculocutaneous nerve
-median nerve
-ulnar nerve
-radial nerve
-axillary nerve
superior trunk comes from
C5 and C6 root
middle trunk comes from
C7
inferior trunk comes from
C8 and T1
lateral cord comes from
anterior divisions from superior and middle trunk
medial cord comes from
anterior division from inferior trunk
posterior cord comes from
posterior divisions from superior, middle and inferior trunk
musculocutaneous nerve comes from
lateral cord
median nerve comes from
lateral and medial cord
ulnar nerve comes from
medial cord
radial nerve comes from
posterior cord
axillary nerve comes from
posterior cord
branches off roots
-dorsal scapular nerve
-long thoracic nerve
dorsal scapular nerve
-C5 root
-innervate rhomboids and portion of levator scapulae
long thoracic nerve
-C5,C6,C7 roots
-innervate serratus anterior
branches off trunks
-nerve to subclavius
-suprascapular nerve
nerve to subclavius
-from superior trunk
-innervate subclavius
suprascapular nerve
-from superior trunk
-innervates supraspinatus and infraspinatus
branches off median and lateral cords
-median and lateral pectoral nerves
-medial cutaneous nerves
median and lateral pectoral nerves
-medial and lateral cord
-innervates pec major and minor
medial cutaneous nerves
-from medial cord
-innervates skin of medial arm and forearm
branches off posterior cord form
-upper and lower subscapular nerves
-thoracodorsal nerve
upper and lower subscapular nerve
-from posterior cord
-innervate subscapularis and teres major
thoracodorsal nerve
-from posterior cord
-innervates latissimus dorsi
musculocutaneous, median, and ulnar nerves innervate
-anterior compartment muscles
-anterior skin of upper limb
radial and axillary nerve innervate
-posterior compartment muscles
-posterior skin of upper limb
