Question | Answer |
basic unit of motor activity | single motor neuron + all the muscle it synapses on |
Lower Motor Neuron | cell body in spinal cord or in brainstemaxon terminates on musclesactively innervates muscle |
Upper Motor Neuron | cell body in brainstem or cotexsynapses on lower motor neuronfine tunes lower motor neuron |
Reflex Arc | receptor, afferent sensory neuron, efferent motor neuron, effector |
muscle spindle | monitors muscle length and rate of change, organized in parallel with extrafusal muscle fibers |
Golgi Tendon Organ | monitors muscle tension, organized in series with extrafusal muscle fibers |
Myostatic reflex basic info | simplest reflex, monosynaptic reflex between muscle spindle and motor neuron, stretch |
Myotatic reflex | contraction/excitation of agonist muscle, relaxation/inhibition of antagonist muscle, comes back to muscle that started sensory, interneuron inhibits antagonist muscle |
Patellar reflex test | stretch reflex, maintain posture |
Inverse myotatic reflex | lengthening, disynaptic reflex between GTO and motor neuron, interneuron inhibits agonist muscle, protects against muscle damage during extreme muscle exertion |
The withdrawal (flexor) refles is initiated by? | noxious stimuli |
A Single Stimulus causes | activation of hip and leg flexors, activation on the opposite side to shift weight to that leg |
