In the torso there are several major muscle groups including the pectoral, and abdominal muscles; intrinsic and extrinsic muscles are subdivisions of muscle groups in the hand, foot, tongue, and extraocular muscles of the eye.
Antagonism is not an intrinsic property of a particular muscle or muscle group; it is a role that a muscle plays depending on which muscle is currently the agonist. During slower joint actions that involve gravity, just as with the agonist muscle, the antagonist muscle can shorten and lengthen.
The iliacus and nearby muscles. The hip flexors are (in descending order of importance to the action of flexing the hip joint): [2] Collectively known as the iliopsoas or inner hip muscles: Psoas major; Iliacus muscle; Anterior compartment of thigh.
