Clavipectoral fascia is pierced by all of the following structures, EXCEPT:
**Core Concept**
The clavipectoral fascia is a layer of connective tissue that separates the pectoralis minor muscle from the subclavius muscle and the suspensory ligament of the axilla. It plays a crucial role in the anatomy of the shoulder region, allowing for the passage of various structures.
**Why the Correct Answer is Right**
The clavipectoral fascia is pierced by several structures, including the pectoralis minor muscle, the subclavian artery, the subclavian vein, the thoracoacromial artery, and the thoracoacromial vein. These structures pass through the fascia to reach their respective destinations. The subclavian artery and vein, in particular, are notable for their passage through the clavipectoral fascia, which allows them to supply and drain the upper limb.

**Clinical Pearl / High-Yield Fact**
To remember the structures that pierce the clavipectoral fascia, recall the mnemonic "PASV" or "Pectoralis, Artery, Vein, Subclavius." This will help you associate the pectoralis minor muscle, the subclavian artery, the subclavian vein, and the subclavius muscle with the clavipectoral fascia.
