[2025-10-01T15:18:24.521419] [PI reasoning] **Analyzing thoracocentesis question**

I'm working on answering a multiple-choice question about thoracocentesis, specifically which structures are pierced. The list includes skin, superficial fascia, and various muscles, but not the pulmonary pleura, as it doesn't get pierced during the procedure. There’s some confusion about "Thoracic fascia"; it might refer to endothoracic fascia, which is indeed pierced. So, the answer to which is not pierced is the pulmonary pleura. I'll use a standard anatomy text for a citation.
