Action potential Neural impulse; brief electircal charge that travels down axon when fired Adrenal glands 2 Small glands located on top of kidneys that produce steroid hormones, adrenaline, noradrenaline; help control heart rate, blood pressure, bodily functions All-or-none law Process by which neuron fires is all or none; either receives sufficient stim from surrounding cells to fire or doesnt; no variation in size of electrical impulse once fired Amygdala Portion of li...

Nissl Stain - ️️Nissl used basic died to stain the endoplasmic reticulum (RNA), thereby revealing cell bodies. Using the nissl stain, Brodmann found that different areas of the cerebral cortex had distinct cytoarchitectonic appearances. He identified 52 cortical areas, now called Broadmann's areas contralaterality - ️️right brain controls left, left brain controls right. most functions are contralateral 3 types of glial cells - ️️Astrocyte (maintain ionic environment), Oligode...

What is the neurotransmitter released by all presynaptic neurons at the ganglia and at synapse of the postsynaptic neurons of the parasympathetic nerves? ~~> Acetylcholine What is the neurotransmitters associated with the sympathetic nerves? They are released at the synapse of the post synaptic neuron. ~~> Norepinephrine, Epinephrine, and Dopamine These are drugs that stimulate the parasympathetic nervous system by mimicking the effects of the PNS neurotransmitter actylchol...

Which of the following does NOT correctly match a term with its description? Depolarization --- Period during which sodium ions diffuse out of the neuron due to a change in permeability for these ions. Repolarization --- The interior of the cell becomes more negative due to the opening of potassium ion gates. Relative refractory period --- An exceptionally strong stimulus can trigger a response (action potential). Absolute refractory period --- Period during which the neuron cannot respond...
