AXILLARY ARTERY Begins as the continuation of subclavian artery at the outer border of first rib. Ends by continuing as brachial artery at the lower border of teres major muscle. Along its course it is divided by pectoralis minor muscle into three parts.
Slide 8-

PARTS: FIRST PART - medial to pectoralis minor muscle. SECOND PART - posterior to pectoralis minor. THIRD PART - lateral to pectoralis minor.
Slide 9-

BRANCHES: I PART: 1.Superior thoracic artery. II PART: 1.Thoraco- acromial artery. 2.lateral thoracic artery. III PART: 1.subscapular artery. 2.ant.circumflex humeral artery. 3.post.circumflex humeral artery.

Slide 11-

BRACHIAL ARTERY Begins as a continuation of axillary artery at the lower border of Teres major muscle. Ends at the level of neck of radius by dividing into radial & ulnar arteries. Accompanied by a pair of venae comitantes.

Branches: Profunda brachii artery. Superior Ulnar collateral artery. Inferior Ulnar collateral artery. Radial artery. Ulnar artery. Nutrient artery.
Slide 14-

Applied anatomy Pulsation of the brachial artery is felt or auscultated in front of the elbow; this helps - recording the blood pressure.

Slide 21-

Branches of radial artery Radial recurrent artery Muscular branch Palmar carpal branch Dorsal carpal branch Superficial palmar branch First dorsal metacarpal artery Arteria princeps pollicis Arteria radialis indicis
Slide 22-

Applied anatomy Radial pulsations.
Slide 23-

SUPERFICIAL PALMAR ARCH
Slide 24-

FORMATION: formed as the direct continuation of ulnar artery laterally completed by one of the following branches of radial artery: i) superficial palmar branch ii) radialis indicis iii) princeps pollicis
Slide 25-

Ulnar artery Ulnar artery Radial artery Common palmar digital artery Proper palmar digital artery Superficial Palmar Arch:
Slide 26-

branches of superficial palmar arch: FOUR PALMAR DIGITAL ARTERIES, arise from the convexity of the arch. The PROPER DIGITAL BRANCH passes along the medial side of little finger. Three COMMON PALMAR DIGITAL ARTERIES , each of which at the base of the interdigital region divide into two proper palmar digital arteries,which supply the adjacent fingers.
Slide 27-

Deep palmar arch
Slide 28-

DEEP PALMAR ARCH: FORMATION: Formed mainly by the terminal part of the radial artery, and is completed medially by the Deep palmar branch of the ulnar artery. BRANCHES: 1.Three palmar metacarpal arteries. 2. Perforating arteries. 3. Recurrent branches

Scapular anastomosis Between the branches of 1st part of subclavian artery and 3rd part of axillary artery.
Slide 31-

SCAPULAR ANASTOMOSIS Between the branches of first part of subclavian artery and the third part of axillary artery. In the subscapular, supraspinous fossa and infraspinous fossa between a) suprascapular artery b) deep cervical artery c) circumflex scapular artery.
