Axillary artery

The axillary artery with branches

When axillary artery ( axillary artery ) is the continuation of the subclavian artery in the armpit designated. It supplies the armpit, the muscles of the shoulder and chest, and the arm .

course

It begins at the outer edge of the first rib and ends at the lower edge of the teres major muscle . From there it continues on the upper arm as the artery of the arm , the brachial artery . It is divided into three parts by the pectoralis minor muscle . It is the central structure of the armpit , and (inner) on its medial side extends their Vein accompanying the axillary ( axillary vein ).

Branching in humans

• Arteria thoracica superior (upper thoracic artery )
• Arteria thoracoacromialis (thoracic bone corner artery)
• Arteria thoracica lateralis (lateral thoracic artery )
• Arteria subscapularis ( subscapular artery , largest branch) with:
  • Thoracodorsal artery
  • Circumflex artery of the scapulae
• Posterior circumflex artery
• Arteria circumflexa humeri anterior

Splitting at the domestic animals

• Arteria thoracica externa (external thoracic artery)
• Arteria suprascapularis (upper shoulder blade artery, originates in predators from the arteria cervicalis superficialis )
• Subscapular artery (subscapular artery), with:
  • Thoracodorsal artery
  • Circumflex artery caudal humerus
  • Radial collateral artery
• Cranial circumflex artery
