2.6 Psych Neuron and Endocrine System

What do we call messengers that send information to and from the brain?

• Blood
• Neurons
• Nerves
• Brain waves

What is the part of the neuron that covers the axon, protects it, and speeds up neural impulses?

• Dendrite
• Soma
• Terminal Button
• Myelin Sheath

What is the electrical charge that travels down the axon of a neuron called?

• Resting Potential
• Refractory Period
• Action Potential

What is the "recharging phase" when a neuron has already fired and cannot fire again called?

• Refractory Period
• Resting Potential
• Action Potential

What is the state of a neuron when it is resting, charged, and ready to generate an action potential called?

• Refractory Period
• Resting Potential
• Action Potential

This law states that if a neuron fires, it will always fire at the same intensity? (100%)- it either fires or it doesn't.

• All or None Principle
• Neural Principle
• Axon Principle
• Terminal Branch Principle

What is the tiny gap between neurons called?

• Terminal Button
• Axon
• Dendrite
• Synapse

What are the chemical messengers that are sent out of terminal buttons and cause the next neuron to fire or not called?

• Neurotransmitters
• Neural Senders
• Axons
• Dendrites

What type of neurons take information TO the brain?

• Motor (Efferent)
• Sensory (Afferent)
• Receptors

What type of neurons send information FROM the brain back to other parts of the body?

• Motor (Efferent)
• Sensory (Afferent)
• Receptor
