Exam 2: Synapses

Glutamate opens sodium gates,enabling sodium ions to enter the postsynaptic cell.What type of effect is this?​

On the basis of what evidence were the properties of synapses first inferred?​

Specialized junctions between neurons are called ____.​

Temporal summation most likely occurs with ____.​

The circuit from sensory neuron to muscle response is called ____.​

Temporal summation is to ____ as spatial summation is to ____.​

Why is the speed of conduction through a reflex arc slower than the speed of conduction of an action potential along an axon?​

The basic building blocks for the majority of neurotransmitters are ____.​

What is the function of the enzyme acetylcholinesterase?​

Briefly compare the differences between ionotropic and metabotropic receptors.Include their mechanisms of action and how they explains the difference in the effects on the postsynaptic cell.​

In a reflex arc,the coordination between contraction of certain muscles and relaxation of others is mediated by ____.​

Inhibitory synapses on a neuron ____.​

Which statement is TRUE of EPSPs?​

"Second messengers" carry their messages to ____.​

Dopamine and norepinephrine are classified as ____.​

Which process indicates spatial summation?​

Sherrington deduced that transmission at a synapse must be slower than conduction along an axon.This was based on what kind of evidence?​

Most of the brain's excitatory ionotropic synapses use the neurotransmitter glutamate.​

When an action potential reaches the end of an axon,the depolarization causes what ionic movement in the presynaptic cell?​

"Transporter" proteins transport neurotransmitters ____.​
