MOG (muscles, organs, glands)
somatic nervous system
voluntary movement
initiates skeletal movement
autonomic nervous system
involuntary movement
keeps body functioning at homestasis
deals with threateninf situaitons (FFF)
visceral muscles
neurochemicals
chemical substances that transmit neural messages
‘lock and key process’
neurochemicals only bind to its complementary receptor site.
neurotransmitters
chemical molecules that have an effect on ONE or TWO postsynaptic neurons
enable rapid communication between neurons
fast acting, localised and short lived
Glutamate
an excitatory (promotes firing an AP) neurotransmitter
stimulates postsynaptic neuron increases likliehood of firing an action potential
associated with learning and memory
form and strengthen synaptic connections between neurons
