(d) Adductors move a limb away from the midline (e)Sphincter turns limbs face downward. (f) Flexor decreased a joint angle (g)Deep muscles are near the skin (surface of a limb) (h) Pronators move limbs to face upward. Muscles controlling hip motion includes flexors-extensors and adductors-abductors. ) Abductors move limbs to face upward (k) Extensors increase a joint angle Flexor moves limbs to face upwards. (m) Adductors move limbs towards the midline (n) Supinator turns a limb to face upward (o)The wrist is distal to the elbow.
