Vessels of Canine Thoracic Limb Flashcards
External thoracic a.
superficial pectorals, may have a common turnk with the lateral thoracic a. or from the deltoid branch of the superficial cervical artery
Axillary a.
Branches into external thoracic a., lateral thoracic a., subscapular a., and cranial circumflex humeral a.
Lateral thoracic a.
latissimus dorsi m., deep pectoral and cutaneous trunci
Subscapular a.
Subscapularis and scapula, can supply part of teres major
Branches into thoracodorsal a. and caudal circumflex humeral a.
Thoracodorsal a.
Teres major, latissimus dorsi
Caudal circumflex humeral a.
deltoideus, coracobrachialis, infraspinatus, part of triceps and shoulder joint capsule
Cranial circumflex humeral a.
cranial aspect of biceps brachii and should joint capsule, last branch of axillary a.
Brachial a.
Branches into deep brachial a., bicipital a., collateral ulnar a., superficial brachial a., transverse cubital a., common interosseous a.
Deep brachial a.
deep into brachium to triceps
Bicipital a.
Biceps and brachialis m.
Collateral ulnar a.
Triceps, caudal elbow area
Transverse cubital a.
cranial elbow and adjacent muscles
Common interosseous a.
Short common trunk, last branch of brachial a.
Median a.
Principal blood supply to the paw; passed through the carpal canal with the DDF to supply the palmar surface of the paw. Branches into radial a. and deep antebrachial a.
Radial a.
Deep vessels of the front paw
Deep antebrachial a.
FCR, DDF, FCU, SDF
Cranial pectoral n.
Superficial pectoral m.
Lateral thoracic n.
Cutaneous trunci m.
Suprascapular n.
Subscapularis
Axillary n.
Teres major, teres minor, deltoideus, part of subscapularis; give off later cutaneous antebrachial nerve
Thoracodorsal n.
Latissimus dorsi
Musculocutaneous n.
Coracobrachialis, biceps brachii, brachialis; cutaneous innervation to the medial aspect of the antebrachium; gives off medial cutaneous antebrachial n.
Radial n.
Motor to all extensors of the carpus, metacarpus, and digits; all of triceps, tensor fascia, anconeus, ECR, CDE, supinator, LDE, and ulnaris lateralis; supplies cutaneous innervation to cranial and lateral surface of antebrachium and dorsal surface
Splits into superficial and deep branches, gives off lateral cutaneous antebrachial n.
Median n.
pronator teres, pronator quadratus, FCR, SDF, parts of DDF; passes through the carpal canal to supply sensation to the palmar surface of the front paw
Ulnar n.
FCU, parts of DDF, also passes through the lateral part of the carpal canal, cutaneous innervation to lateral surface of the metacarpus and the fifth digit; gives off caudal cutaneous antebrachial n.
Caudal pectoral n.
deep pectoral, often combine with the lateral thoracic n. at its origin
