muscular system structures

muscles, tendons, aponeuroses

muscular system functions

movement, posture, body heat

smooth muscles

digestion

cardiac muscles

heart

skeletal muscle

bones

tendons

connect muscle to bones “Chords”

aponeuroses

connnect muscle to bones, muscle, skin “sheet”

endpmysium

cover muscle fiber

perimysium

cover fascicle

epimysium

cover whole muscle

fascicles

bundles of muscle fibers, covered by perisium

muscle fiber

myofibrils combined

myofibrils

thin strands that make up a fiber strand

filaments

thick and thin proteins in muscles

actin

thin filaments

myosin

thick filament

sarcomeres

repeating patterns within muscle fibers

neurotransmitters

chemical messages connected to the cell

acetylchlorine

makes muscles contract

motor neuron

controls effectors

synapse

meeting center of the motor neuron and muscle fiber

synaptic cleft

space between cell and synapse

origin

less moveable end

insertion

more movable end

agonist

prime mover

synergists

works with prime mover

prime mover

provides most of the force for a movement

antagonist

works against prime mover/action
