NGSS.MS-LS1-2

Type of neuron that sends nerve impulses to muscles and gland, by the command of other neurons.

• Motor Neurons

• Interneurons

• Sensory Neurons

What do Dendrites do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon

What do Axon Terminals do?

• Intakes information from other neurons

• Produces fatty tissue for the Myelin Sheath

• Sends information to the next cell

• Controls the speed of electrical signal through the axon

What is the insulating membrane that surrounds parts of the axon that helps the impulses travel faster called?

• Axon
• Dendrites
• Node of Ranvier
• Myelin Sheath

What is the chemical used by a neuron to transmit an impulse across a synapse to another nerve cell?

• Neurotransmitters
• Synapse
• Threshold
• Impulse

This is the electrical charge that travels down an axon when a neuron is firing

• Resting Potential
• Action Potential
• Threshold
• Refractory Period

The correct direction of the neural impulse within one neuron.

• Axon Terminal to Dendrite
• Dendrite to Axon Terminal
• Cell Body to Axon
• Axon Terminal to Cell Body

Which two organs make up the Central Nervous System(CNS)?

• Brain and Heart

• Brain and Lungs

• Brain and Nerves throughout the body
