An action potential is generated at the... trigger zone of the axon postsynaptic membrane cell body axon terminal

Aerobic, or low-intensity, muscle training eventually results in A more muscle fibers more capillaries C more glycogen D more myoglobin E B and D are correct B

Draw a presynaptic and postsynaptic neuron at to demonstrate the release and acceptance of a neurotransmitter. Identify the following in your drawing: Ca2+, synaptic cleft, receptor, synaptic vessicle, SNARE, presynaptic neuron, postsynaptic neuron

Describe at least 2 processes at the synapse that shift the effect of an action potential of a pre synaptic cell on the response of a post synaptic cell.

Why does an action potential move in an all-or-nothing fashion down the length of an axon without stopping?

rearrange these in the correct order of events in an action potential.

What is the term used to describe the rounded lump located at the end of the axon? synapses receptor sites terminal button O synaptic vesicles

What is the arrow identifying in the picture below? soma dendrite O action potential Oaxons axon hillock < Previous M

In terms of function when a presynaptic neuron receiving input from a nearby inhibitory neuron, it can be inferred that the both neurons firing won't be synchronized activation of the inhibitory neuron is nullified activation of the presynaptic neurotransmitter release is enhanced this type of interaction represents a regulatory input of neuronal activation

Early in an action potential, the inside of the axon becomes less negatively charged relative to the outside, this is called.   Polarization  Depolarization  Hyperpolarization  Repolarization ---------------------------------- Neurotransmitters -gated (ligand gated) ions channels are important for ____, while voltage gated ion channels are important for ____    Communication between neurons; communication within neurons    communication within neurons; Communication between neurons ------------------------------- In gross neuroanatomy we are interested in structures that are NOT visible to the naked eye.  True or false.
