Anatomy

myosatellite cells

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

gatekeepers at entrances and exits

muscle fiber *muscle cells *multinucleated

terminal branches of axons *neurons

indirect: tendon, aponeurosis

glycemic control

amino acid reserve

upporting and protecting soft tissues

muscle connections:direct or indirect

generating body heat

endomysium *around each muscle fiber

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

capillaries

all connected: endomysium-perimysium-epimysium

posture and body position

fascicles: *bundles of muscle fibers *surrounded by

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

excitability

Sarcolemma:has resting membrane potential

myofibrils

striations

on signal from neuron to contract

general function:movement

electrochemical

contractility

elasticity

negative charge inside

multinucleate

all cells maintain resting membrane potential

extensibility

glycogen granules

sarcoplasm

sarcolemma

very large
