muscle type Flashcards
muscle three type
smooth, vardia, skletcal
skeletral moves limbs
flexor,extention,synergistic(same movement),antagonist(act opposite)
neuromuscular junctions
terminal botton of motor neuron synape on motot endplates
moto endplates stimulated
acetylcholine— released by neuromuscular junctions– bind recptor motor endplatp—depolarising endplate— cause move
single motor neuron
single motor neuron— input—- multiple muscle fibes
strength- depends fire rating
sensory feedback= propioceptor
provides form position info on joint angle
propioceptor - muscle spinder
help form position of limb-muscle spindles(tissue)
lengthens spindle- sent to spinal cord
propioceptor - glogi tendon
tendons
how hard muscle increase— send spinal cord
function
- Muscle strength— spindle fires— carried to spinal corded—- synapse stimulated motor neuron— back to muscle
cerebellum- modulate motor action
tunes correct movement
- balance posture
basal glanglia
control movement
motor sensory info about planned movement
issues in basile glanglia
parkingsons- excilitatory and inhibitory circuits behaviour
