How do extrinsic and intrinsic muscles int he hindlimb relate to each other and why is this the case?
Extrinsic muscles movem the limb relative to the trunk. They originate on the axial skeleton & pelvis and insert onto the appendicular skeleton. Intrinsic muscles both originate and insert onto the appendicular skeleton. They function to extend and flex the joints of the limb. However the pelvis acts as part of the axial skeleton therefore overlap occurs between hindlimb extrinsic and intrinsic muscles and their functions.
