1. Identify the type of neuron that…

1. Brings information to the brain SENSORY

2. Carries information from the brain to the muscles and glands MOTOR

3. Communicates information between neurons INTERNEURON

2. Most neurons in the human nervous system are INTERNEURONS

3. Identify the part of a neuron that…

   1. Processes nutrients and provides energy for the cell to function SOMA

   2. Covers axons MYELIN SHEATH

   3. Receives information from other neurons DENDRITES

   4. Carries information away from the cell body (long tube) AXON

   5. Is the location of the synaptic vesicles AXON TERMINAL BUTTONS

   6. Contains neurotransmitters SYNAPTIC VESICLES 

4. What is the tiny space between two neurons called? SYNAPSE

5. What part of the neuron increases the communication speed of a neuron? MYELIN SHEATH

6. What part of the neuron is linked to multiple sclerosis? MYELIN SHEATH

7. Using the numbers 1-4, identify the path that an impulse travels through a neuron. 

3 Axon 1 dendrites 4 axon terminals 2 soma

8. What cells provide structural support to neurons? GLIAL CELLS

9. Define action potential: A NEURAL IMPULSE; A BRIEF ELECTRICAL CHARGE THAT TRAVELS DOWN AN AXON. THE ACTION POTENTIAL IS GENERATED BY THE MOVEMENT OF POSITIVELY CHARGED ATOMS IN AND OUT OF CHANNELS IN THE AXON'S MEMBRANE.

10. Briefly describe how one neuron transmits an impulse to another neuron using the following terms correctly to describe the process of neural transmission: Axon, action potential, terminal branches of axon, neurotransmitter, synapse, receptor site, and dendrite.
