Term
What are the parts of a neuron and the correct ond the correct order that an impulse would pass through?
Definition
Dendrite --> Cell Body --> Axon
Term
In a neuron, what does the Dendrite do?
Definition
Recieves Impulses
Term
In a neuron what does the Cell Body contain?
Definition
Nucleus, Cytoplasm, And organelles
Term
In an neuron, What does the axon do?
Definition
Carries impulses away from cell body
Term
What is a synapse?
Definition
The space that lies between one neuron's axon and another's dendrite
Term
What is the function of Sensory Neurons?
Definition
To carry impulses from body to the brain and spinal cord
Term
What is the function of Interneurons, and where are they found?
Definition
Found within the brain; Process incoming impulses

Term
What is the main function of the Spinal Cord?
Definition
It connects the brain to peripheral nervous system; functions in reflexes
Term
What is a Neurotransmitter?
Definition
Chemicals used by a neuron to transmit an impulse across a synapse to another cell
Term
What is a Hormone?
Definition
Chemicals released in one part of the body that travel through the blood stream and affect the activities of a cell in other parts of the body
