• fascicles: *bundles of muscle fibers *surrounded by

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

• upporting and protecting soft tissues

• capillaries

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

• glycemic control

• endomysium *around each muscle fiber

• perimysium-fibrous connective tissue sheath blood vessels nerves

• all connected: endomysium-perimysium-epimysium

• terminal branches of axons *neurons

• myosatellite cells

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

• muscle connections:direct or indirect

• amino acid reserve

• movement of the skeleton and skin

• posture and body position

• muscle fiber *muscle cells *multinucleated

• generating body heat

• gatekeepers at entrances and exits

• indirect: tendon, aponeurosis
