(c) muscle attachments

• gatekeepers at entrances and exits

• endomysium *around each muscle fiber

• all connected: endomysium-perimysium-epimysium

• myosatellite cells

• muscles can only pull *prime mover & antagonist on opposite sides of joint

• posture and body position

• terminal branches of axons *neurons

• all connected: endomysium+perimysium+epimysium-tendon, aponeurosis,or direct attachment

• can be more than one agonist (prime mover; major responsibility for producing specific movement
