Cells in the nervous system that communicate with one another to perform information-processing tasks.
What are neurons?
100
Support cells found in the nervous system
What are glial cells?
100
The difference in electric charge between the inside and outside of a neuron's cell membrane.
What is resting potential?
100
An interacting network of neurons that conveys electrochemical information throughout the body.
What is the nervous system?
100
Drugs that increase the action of a neurotransmitter.
What is agonist
200
The part of the neuron that coordinates information-processing tasks and keeps the cell alive.
What is the cell body?
200
The junction or region between the axon of one neuron and the dendrites or cell body of another neuron.
What is a synapse?
200
An electric signal that is conducted along a neuron's axon to a synapse
What is action potential?
200
The part of the nervous system that connects the central nervous system to the body's organs and muscles.
What is the peripheral nervous system?
200
Drugs that block the function of a neurotransmitter
What is antagonist
300
The part of a neuron that receives information from other neurons and relays it to the cell body.
What is the dendrite?
300
Neurons that receive information from the external world and convey this information to the brain via the spinal cord.
What are sensory neurons?
300
The time following an action potential during which a new action potential cannot be initiated.
What is the refractory period?
300
The part of the nervous system that is composed of the brain and spinal cord.
What is the central nervous system?
300
A thick band of nerve fibers that connects large areas of the cerebral cortex on each side of the brain and supports communication of information across the hemispheres.
What is the corpus callosum?
400
The part of a neuron that transmits information to other neurons, muscles, or glands.
What is the axon?
400
Neurons that carry signals from the spinal cord to the muscles to produce movement.
What are motor neurons?
400
Chemicals that transmit information across the synapse to a receiving neuron's dendrites.
What are neurotransmitters?
400
A set of nerves that conveys information into and out of the central nervous syetem
What is the somatic nervous system?
400
A set of nerves that prepared the body for action in threatening situations.
What is the sympathetic nervous system?
500
An insulating layer of fatty material.
What is the myelin sheath?
500
Neurons that connect sensory neurons, motor neurons, or other neurons.
What are interneurons?
500
Parts of the cell membrane that receive the neurotransmitter and initiate or prevent a new electric signal.
What are receptors?
500
A set of nerves that carries involuntary and automatic commands that control blood vessels, body organs, and glands.
What is the autonomic nervous system?
500
A set of nerves that helps the body return to a normal resting state.
