Anatomical terminology []

The thoracoacromial artery (acromiothoracic artery; thoracic axis) is a short trunk that arises from the forepart of the axillary artery, its origin being generally overlapped by the upper edge of the Pectoralis minor.

Projecting forward to the upper border of the Pectoralis minor, it pierces the coracoclavicular fascia and divides into four branches—pectoral, acromial, clavicular, and deltoid.

Mnemonics used to remember the four branches are:

The axillary artery and its branches.
