Pectineus

pectineus -- 2016
Pectineus

Pictured above is the pectineus muscle. It is nick-named the "4th adductor" muscle and it pulls the thigh toward the pubic bone. When this muscle is overly tight (and this is true for many of us), you will have trouble comfortably opening your legs really wide. This leads to compromised leg positioning for some functional movements such as the deep squat.

The muscles are layered, showing how some of the muscles are covered by the others. All of the muscles are see-through so that you can appreciate the location and size of each muscle relative to the others.
