Anatomy

terminal branches of axons *neurons

perimysium-fibrous connective tissue sheath blood vessels nerves

muscle fiber *muscle cells *multinucleated

gatekeepers at entrances and exits

generating body heat

fascicles: *bundles of muscle fibers *surrounded by

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

glycemic control

endomysium *around each muscle fiber

amino acid reserve

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

movement of the skeleton and skin

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

upporting and protecting soft tissues

posture and body position

all connected: endomysium-perimysium-epimysium

indirect: tendon, aponeurosis

muscle connections:direct or indirect

capillaries

myosatellite cells

heart

involuntary

walls of hollow organs

striated muscle
