Latin muscle parts
Thigh muscle – medial compartment
This muscle’s name in English is the comb muscle. The word pectineus comes from the Latin pecten, which translates as “comb.” Os pecten was originally the name given to the bone now referred to as the pubic bone. The prong-like nature of this bone resembled an ancient comb. Since this muscle attached to the comb-bone it became the comb-muscle.
