Nerves and Nerve Impulse

The tiny gap between an axon terminal of one neuron and the dendrite of a second neuron.

• synaptic cleft

• axon terminal

• impulse

• myelin

This is the term referring to the electrical charge that travels down an axon when a neuron is firing.

• Resting Potential

• Action Potential

• Threshold

• Refractory Period

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

• Neurotransmitter

• Synapse

• Threshold

• Impulse

Which of the following is the correct order of the direction of a message?

• Dendrite-Cell Body-Axon-Synapse
• Synapse-Cell Body-Axon-Dendrite
• Dendrite-Synapse-Cell Body-Axon
• Axon-Cell Body-Dendrite-Synapse

This part of the neuron stores then releases neurotransmitters into the synaptic cleft.

• Axon

• Dendrite

• Myelin Sheath

• Axon Terminal

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

• Dendrites

• Axon Terminals

• Myelin Sheath

• cell body

• Dendrites

• Axon Terminals

• Myelin Sheath

• Schwann Cells

• Nucleus

• Cell Body

• axon terminal

• Node of Ranvier

• Nucleus

• Cell Body

• Axon

• Node of Ranvier
