Exam 10: Neurotransmitters, Prozac, and Neurons

The ______________ is the most basic signal in the nervous system which consists of a rapidly moving wave of depolarization that travels along the membrane of the individual neuron.

________________ refer to simple, automatic behaviors that are produced by the spinal cord and occur without involvement of the brain.

_______________ is the part of a neuron that contains the nucleus.

______________neurons communicate information from one neuron to the next.

________________ is the neurotransmitter that inhibits brain activity.

Additional evidence indicates that ___________________ also serve to intensify positive sensations- for example, the "runner's high" many people experience after vigorous exercise.

________________ is the point of communication between two neurons.

_______________ is a type of neuron that signals muscles to contract or relax.

_____________ are made up of large bundles of neuron axons.

When an action potential reaches the axon terminal, synaptic vesicles move toward the _____________________.

_________________ are the small gaps in the myelin sheath surrounding the axons of many neurons.

Prozac works by inhibiting the reuptake of __________________, increasing the availability of this neurotransmitter in the brain.

______________ is the long, fluid-filled tube that carries a neuron's messages to other body areas.

_______________ is the primary internal communication network of the body; divided into the central nervous system and the peripheral nervous system.

_______________ is a chemical messenger manufactured by a neuron.

The ________________ is a tiny space between the axon terminal of one neuron and the dendrite of an adjoining neuron.

_________________ is a neurotransmitter that is involved in the regulation of bodily movements and thought processes.

Degeneration of ___________________ producing neurons has been linked to Parkinson's disease.

_________________ carry information toward the cell body.

Within the axons of the neuron are _________________, which are held in storage-like vesicles until they are released when the neuron is stimulated.
