Arteries, veins, nerves of thoracic limb Flashcards
External thoracic A
may arise from a common truck with lateral thoracic A or from the deltoid branch of the superficial cervical; A
Lateral thoracic A
Runs caudally along dorsal border of deep pectoral ventral to lats
Subscapular A
Caudodorsally b/t subscapularis & Teres major
Thoracodorsal A
on deep surface of latissimus dorsi
Caudal circumflex humeral A
courses laterally b/t the head of the humerus & Teres major
Cranial circumflex humeral A
From axillary A distal or proxoimal to the subscapular A
Brachial A (DOG)
continuation of the axillary A
Deep brachial A
to muscles of caudal brachium; may come off the median A; can be more than one
Bicipital A
enters the biceps brachii M
Collateral ulnar a
Caudal branch in distal 1/3 arm; follows the ulnar N
Superficaial brachial A
Loops around cranial surface of distal biceps brachii
Common interosseous A
short; passes to proximal part of the interosseous space then divides
Ulnar A
courses caudally and continues distallly w/ ulnar N
Caudal interosseous A
lies b/t apposed surfaces of the radius and ulna
Cranial interosseous A
thur proximal part of the interosseous space cranially
Radial A
from medial side of median A in mid- forearm
Deep antebrachial A
Caudal branch of median A
Accessory cephalic V
Joins cephalic V on cranial surface of distal 1/3 of forearm
Median cubital V
connection b/t cephalic and bracnial Vv
Axillobrachial V
Leaves caudal aspect of cephalic
Omobrachial V
Subcutaneous across cranial surface of the arm
Cranial pectoral Nn
Superficical pectoral M
Suprascapular N
b/t the suprespinatus & subscapularis Mm, crosses scapular notch
Subscapular N
could have 2 nerves entering subscapularis M
