Nerve Impulse Transmission

What is structure labeled D in the picture?

• Dendrite

• Axon

• Cell Body

• Axon Terminal

An electrical impulse within a single neuron is called a

• synapse

• membrane potential

• action potential

• cell body

What is the advantage of reflex actions?

• They allow for quick responses to stimuli without conscious thought

• They help in complex decision-making processes

• They only occur in animals with advanced nervous systems

• They are under voluntary control

In a simple reflex arc, what is the correct sequence of components?

• Sensory neuron → Interneuron → Motor neuron

• Motor neuron → Sensory neuron → Interneuron

• Interneuron → Motor neuron → Sensory neuron

• Sensory neuron → Motor neuron

A single fiber in the neuron that carries impulses away from the cell body:

• axon

• dendrite

• myelin sheath

• nucleus

Fat covering that increases the rate of transmission and insulates the axon:

• axon

• dendrite

• myelin sheath

• schwann cell

Special chemicals which allow the impulse to jump across the synapse to pass to another neuron:

• neurotransmitters

• schwann cells

• myelin sheath

• nerves

The space between neurons:

• neurotransmitter

• synapse

• terminal branches

• schwann cells

Which is represented by the letter E?

• Axon

• Myelin sheath

• schwan cells

• axon terminal

Nerve fibers in the neuron that carries impulses toward the cell body:

• axon

• dendrite

• nucleus

• myelin sheath
