The Axillary artery changes names when the blood vessels pass underneath the:
Clavicle and enters the axilla
The axillary will then become _____ _____ about an inch or so below the surgical neck of the humerus
Brachial artery
First branch to come off the axillary artery, just as the vessel emerges from under the clavicle

This branch supplies the Pectoralis major/ minor, the subclavius muscle, and the wall of the thorax
Superior Thoracic
Short trunk that curls around the upper border of the pectoralis minor and divides into 4 branches
Thoracoacromial
Name the 4 branches of the Thoracocaromial artery
Clavicular, acromial, Deltoid, Pectoral
Appears along the lateral border of the pectoralis minor
Lateral thoracic
Supplies the: Serratus anterior both pectoral muscles Mammary glands intercostal muscles
Lateral Thoracic
Largest branch of the axillary artery & found parallel and lateral to the lateral thoracic branch and divides into 2 branches
Subscapular
What are the 2 branches of the Subscapular artery:
Scapular circumflex and Thoracodorsal
Thoracodordal artery of the subscapular artery supplies:
Latissimus dorsi and the subscapularius muscles
Scapular circumflex artery of the subscapular artery supplies
Supraspinatus infraspinatus, teres major and minor, triceps brachii and part of the deltoid
Anterior & posterior humeral circumflex branches form a circle around the surgical neck of the humerus along with the axillary artery nerve they supply:
Deltoid muscle, shoulder joint, teres muscles and the proximal part of the humerus
Axillary VEIN becomes the ________ ____ as it passes under the clavicle & into the cervical region
