Axillary Artery Mnemonics

Origin of Axillary Artery: Continuation of Subclavian artery

Extent of Axillary Artery: Outer border of 1st rib to Lower border of teres major (terminates as brachial artery)

Relation to Axillary Vein: Lateral to Axillary Vein

3 Parts of Axillary Artery: In relation to Pectoralis Minor muscle

1. 1st part: Proximal
2. 2nd part: Posterior
3. 3rd part: Distal

Branches of Axillary Artery

Mnemonic:

1st part gives 1 branch, 2nd part gives 2 branches and 3rd part gives 3 branches.

Remember: SALt SPAce or Sixties Teens Loves Sex And Pot

• Superior, Acromio- and Lateral thoracic artery
• Subscapular, Posterior circumflex humeral, Anterior circumflex humeral (they run through spaces, i.e. triangular and quadrangular – see below)

Also remember: Teens grow up and die, i.e. Thoraco-acromial artery runs up (superiorly) and gives off 4 branches. “Cadavers Are Dead People” to remember 4 branches of thorac0-acromial artery –

1. Clavicular
2. Acromial
3. Deltoid
4. Pectoralis

Also remember: Sex goes down and ends in STd, i.e. Subscapular artery runs inferiorly and gives off 2 branches –

1. Scapular circumflex artery
2. Thoraco-dorsal artery

1st part: 1 branch

1. Superior thoracic artery

2nd part: 2 branches

1. Acromio-thoracic artery
2. Lateral thoracic artery

3rd part: 3 branches

1. Subscapular artery – cirumflex scapular artery travels through triangular space
2. Anterior circumflex humeral artery
3. Posterior circumflex humeral artery – travels through quadrangular space
