Exam 5: How Do Neurons Communicate and Adapt

A metabotropic receptor consists of:

The synapse between two neurons is surrounded by many structures, such as a(n) _____, which contributes to chemical neurotransmission by supplying the building blocks for neurotransmitters, confining the movement of the neurotransmitters to the synapse, and cleaning up excess neurotransmitters.

Most _____ is (are) assembled on the neuron's ribosomes, packaged in a membrane by Golgi bodies, and transported to the terminal buttons via microtubules.

Electrical synapses _____ in mammals.

Parkinson disease is linked with the loss of _____ neurons in the midbrain.

A(n) _____ is formed when connexin proteins in one cell membrane make a hemichannel that connects to a hemichannel in an adjacent cell's membrane, allowing ions to pass between the two neurons in both directions.

Describe neurotransmission in the somatic nervous system (SNS).

What are the four main amino acid transmitters, and what are their functions?

Gap junctions:

Synaptic vesicles release neurotransmitters via:

What is a neurotransmitter?

_____ was the first neurotransmitter discovered in the CNS.

The rate by which dopamine, epinephrine, and norepinephrine can be synthesized is controlled by a rate-limiting factor that is linked to the availability of:

What are the differences between chemical synapses and electrical synapses? What functions do they serve?

What behaviors are associated with the serotonergic system? Which disorders result from increased or decreased activity in serotonin neurons?

The substance MPTP has been found to be selectively toxic to _____ neurons.

What are the four criteria used to determine whether a substance is a neurotransmitter?

The notion that the nervous system communicates using chemical messages was first demonstrated by:

Which of the following activating system-cell body location pairs is NOT correct?

Which type of synapses have round synaptic vesicles, are typically located on dendrites, and have dense material in the presynaptic and postsynaptic membranes?
