muscle fiber *muscle cells *multinucleated
endomysium *around each muscle fiber
capillaries
terminal branches of axons *neurons
myosatellite cells

perimysium-fibrous connective tissue sheath blood vessels nerves
all connected: endomysium-perimysium-epimysium
muscle connections:direct or indirect
indirect: tendon, aponeurosis
all connected: endomysium+perimysium+epimysium-tendon, aponeurosis,or direct attachment
