The two sides of the crotch bone bulge two piles of meat, the formation of the main two reasons, 1, is due to the crotch bone on both sides of the femur rotor, which is the bony mark of the human body, when touching with the hand, can obviously feel the bony protrusion, so in the crotch bone on both sides feel like bulging up. The actual fact is that there is a lot of soft tissue attached to it, and there is a lot of adipose tissue distributed around the femoral rotor, so it feels like the bulging meat is more obvious. 2, due to the broad fascia tensor muscle. The human body’s broad fascia tensor muscle is mainly responsible for the hip joint abduction action, for some people who often do hip joint abduction, the broad fascia tensor muscle strength is greater, and the muscle tissue is thicker, so it feels like bulging compared to other surrounding tissues, which is also a normal physiological structure.
