Neural Control Of Exercising Muscle 2

Where is NT stored?

in synaptic vesicles of chemical synapses

What are the functions of a NT?

chemical messenger, carry electrical AP signal across synaptic cleft, bind to receptor on postsynaptic surface, stimulate GPs in postsynaptic neuron

What enzyme is at the site of neuron to muscle communication?

acetylcholine

What is the process for neuromuscular junction?

Ach binds to receptor on motor end plate
causes depolarization
AP moves along plasmalemma, down t-tubules
repolarization, refractory period

What are the two chemical synaptic receptors?

ionotropic and metabotropic

What are the types of NT?

inhibitory and excitatory

What stimulates skeletal muscle contraction and mediates the parasympathetic nervous system

ACH

What mediates the sympathetic nervous system?

norepinephrine

What happens when multiple EPSP or IPSP happen?

summation; more depolarizing
summation; more hyperpolarizing

Parts of the brain?

cerebrum, diencephalon, cerebellum, brain stem

What allows the left and right hemispheres to cummunicate?

corpus calosum

What is the cerebral cortex?

the outermost layer of the cerebrum, gray matter (unmyelinated), the conscious brain

What are the lobes of the cerebrum and their functions?

frontal; general intellect, motor control
temporal; auditory input, interpretation
parietal; general sensory input, interpretation
occipital; visual input, interpretation
insular; emotion, self-perception

Where is the primary motor cortex located? What is its purpose?

cerebrum; conscious control of skeletal movement

What is basal ganglia? What are the exercises associated?

cerebral white matter; walking, running, posture, muscle tone
