Exam 37: Neurons, Synapses, and Signaling

For the following questions, refer to the graph of an action potential in Figure 37.1. Figure 37.1 -The membrane's permeability to sodium ions is at its maximum at label

The release of acetylcholine from the terminal of a motor neuron is most directly linked to the

The heart rate decreases in response to the arrival of

In a simple synapse, neurotransmitter chemicals are released by

When several IPSPs arrive at the axon hillock rapidly in sequence from a single dendritic location, hyperpolarizing the postsynaptic cell more and more and thus preventing an action potential, this is an example of

Neurotransmitters categorized as inhibitory are expected to

For a neuron with an initial membrane potential at -70 mV, an increase in the movement of potassium ions out of that neuron's cytoplasm would result in the

Receptors for neurotransmitters are of primary functional importance in assuring one-way synaptic transmission because they are mostly found on the
