Final Answer:
The canal that lies on the lateral wall of the ischioanal fossae courses within which fascia is the: Pelvic fascia so the option is A.
Step-by-step explanation:
The canal that lies on the lateral wall of the ischioanal fossae is called the pudendal canal. This canal contains the pudendal nerve, artery, and vein. The pudendal canal courses within the pelvic fascia. Pelvic fascia refers to the connective tissue within the pelvic region that provides support and structure to various organs, blood vessels, and nerves. In this context, it surrounds and contains the pudendal canal within the ischioanal fossae, contributing to the anatomy of the pelvic floor.
The pudendal canal, which contains the pudendal nerve, artery, and vein, courses within the parietal fascia of the ischioanal fossa. The parietal fascia is a connective tissue layer that lines the walls of various body cavities, and in this case, it surrounds and contains the pudendal canal within the ischioanal fossa. I appreciate your understanding and clarification.
