According to About.com, the muscles located on the inner thigh by the pelvic area are called the adductor muscle group. This muscle group, which is also called the groin muscles, consists of six muscles in total.
About.com explains that the main function of these muscles is to pull the legs together. Additionally, adductor muscles aid with the movements of the joint of the hips. This muscle group is especially important to athletes, such as soccer players, football players, sprinters and swimmers. When these muscles are stretched too far, an injury called groin pull may occur. When the adductor muscles become strained, mild discomfort to severe pain may be experienced.
