The first time I studied inguinal anatomy, I was completely confused. Recently, I revisited systemic anatomy and got stuck here again. After watching several videos, I selected some that I think are good to recommend.
First, watch Teacher Huo Kun’s hand-drawn systemic anatomy
Inguinal anatomy starts at 22:00 in P17 Musculature Trunk Muscles 2
PS: If you have completely forgotten abdominal anatomy, please start from the beginning of P17
