The clavipectoral fascia is penetrated by which aery?
assistant
The correct answer is  The thoracoacromial aery pierces the clavipectoral fascia before giving off its four branches: pectoral, clavicular, deltoid, and acromial. It supplies pectoralis major, pectoralis minor, the deltoid muscle, and the mammary gland. It is a branch off of the axillary aery. The axillary aery and all its other branches, including the anterior circumflex humoral and subscapular aeries, run deep to the clavipectoral fascia. The thoracodorsal aery is a branch of the subscapular aery which also runs deep to the fascia.
