Exam 2: Communication Within the Nervous System

Which transmitter is involved in schizophrenia and Parkinson's disease?

The cells that produce myelin in the peripheral nervous system are called:

Nicotinic receptors are ___ and are found ___;muscarinic receptors are ___ and are found ___.

The lipids that compose the cell membrane are arranged with "heads" and "tails" such that:

At the peak of the action potential,which of the following ionic movements restores the neuron to its resting potential?

The force by which high concentrations of ions disperse away from each other and thus spread evenly through a solution is called:

The connection point between two neurons is called the:

A movement of the resting membrane potential from -70 mV to -90 mV would be termed a(n):

Graded potentials decreased in size as they spread;the term for this is:

Excitatory is to inhibitory as ___ is to ___.

The ___ the axon,the ___ is the conduction rate.

The axon terminals of neurons:

The cells that produce myelin in the central nervous system are called:

In motor neurons,the axon and the dendrites branch out from the soma in several directions,giving this type of neuron the designation of a ___ neuron.

Partial depolarizations die out over a short distance;these depolarizations are known as:

Saltatory conduction occurs only in:

Explain the all-or-none law in the generation of an action potential.

The ___ is the difference in electrical potential between the inside and outside of an inactive neuron.

Motor neurons are typically ___ while sensory neurons are typically either ___ or ___ neurons.

The IPSP produced by acetylcholine is terminated by reuptake.
