Investigation 8: Neurons

A neuron is...

• A special cell in the eye
• A cell only found in the brain
• Cells that don't communicate
• Cells that carry messages and make up nerves

A change in the environment that triggers a sense

• Response
• Stimulus
• Reaction
• Sinus

The pathway of neurons that a messages travels from start (stimulus) to finish (reaction)

• Brain Pathway
• Neural Pathway
• Optic Pathway
• Spinal Pathway

How you react to a stimulus

• Response
• Crazy
• Stimuli 
• Kick

The time it takes for a stimulus to produce a response

• Double time
• Reaction time
• Stimulus time
• Daylight Savings Time

Brings information to the brain from the senses travels

• Motor neurons
• Muscle Neurons
• Sensory Neurons
• Fast neurons

Synapse... 

• The axon between neurons
• The dendrite between neurons
• The neurotransmitters
• The gap between neurons

Part of a neuron that carries the impulse away

• Axon
• Synapse
• Neurotransmitter
• Dendrite

Takes the messages from the brain out to the muscles

• Sensory Neuron
• Spinal Neuron
• Optic Neuron
• Motor Neuron

Chemicals that take the message across the synapse of neurons

• Neurotransmitters
• Neurons
• Dendrites
• Axons
