Neurons & Nervous System part 3

a chemical synapse between motor neurons & skeletal muscle cells

A motor neuron releases __ from its axon terminals.

The postsynaptic membrane of the muscle cell is the __

Voltages due to synaptic transmission & measured in the muscle are called __

main neurotransmitters in the CNS

Glutamate is __ and will result in __, but the __ of different receptors varies significantly

__ receptors allow a rapid influx of Na+

__ receptors first require a slight depolarization through other receptors & allow a slower Na+ influx, as well as Ca2+

Neurotransmitters are cleared from the cleft after release in order to stop their action in several ways:

The postsynaptic cell must sum the __. Summation occurs at the __.

adds up messages at different synaptic sites

adds up potentials generated at the same site over time

Drugs treat the nervous system by modulating __

mimic or potentiate the effect of a neurotransmitter

block the actions of a neurotransmitter
