Neurons
This is referred to as the control center of the cell
What is the nucleus
The chemicals by which neurons communicate
What is neurotransmitters
This cell protects and supports neurons
What is neuroglia
This is a group of peripheral nerve fibers bundled together like the strands of a cable
What are nerves
This division contains the brain and spinal cord
What is the central nervous system
These cells transmit impulses TO the cell body
What are dendrites
What is serotonin
These neuroglia are referred to as "star cells."
What are astrocytes
This word means cannot divide
What is amitotic
This division contains the nerves
What is the peripheral nervous system
These cells transmit impulses AWAY from the cell body
What are axons
This neurotransmitter helps contract all 3 types of muscle tissue
What is acetylcholine
What is microglia
This word is associated with nerve impulses
What is action potential
This division of the peripheral nervous system is associated with normal, everyday conditions
What is the parasympathetic division
The white, fatty substance that wraps around the axon
What is myelin
This neurotransmitter is a stress hormone
What is norepinephrine
This neuroglia produces the fatty myelin sheath in the brain and spinal cord
What are oligodendrocytes
These are the beginnings of dendrites of sensory neurons
What are receptors
This division of the peripheral nervous system is associated with feelings of anger and hate
What is the sympathetic division
This part of a neuron contains the nucleus
What is the cell body
This neurotransmitter is referred to as a "reward drug."
What is dopamine
This neuroglia produces the fatty myelin sheath in the peripheral nervous system
What are schwann cells
These are the organs that put nerve signals into effect
What are effectors
This division of the peripheral nervous system is associated with strenuous exercise and a faster heartbeat
What is the sympathetic division
