The muscles in the thigh are categorized into medial, anterior, and posterior groups, each with distinct functions and innervations. The medial compartment primarily focuses on adduction of the thigh, involving muscles like the adductor longus, adductor magnus, gracilis, obturator externus, and adductor brevis, most of which are innervated by the obturator nerve.
