7.1 - How the Nervous System Works

When chemicals are released by neuron A to the synapse and bind to the receptors of neuron B.

• Electrical Signal will be created in neuron B

• Chemical Signal will be created in neuron B

• Electrical Signal will be created in neuron A

• No signal will be created in neuron B

In a neuron, identify which structure receives impulses and which structure sends impulses to another neuron.

• Dendrites: receive impulses; Myelin: sends impulses

• Axon: receive impulses; Axon tip: sends impulses

• Axon: receive impulses; Myelin: sends impulses

• Dendrites: receive impulses; Axon terminal: sends impulses

Classify which kind of neuron connect various neurons within the brain and spinal cord.

• Sensory neuron

• Motor neuron

• Interneuron

• Thinking neuron

Classify which kind of neuron is involved when you pick up your pen to write.

• Sensory neuron

• Motor neuron

• Interneuron

• Thinking neuron

A nerve impulse travels in the form of

• Electrical and solar signals

• Chemical and solar signals

• Electrical and mechanical signals

• Electrical and chemical signals

What are the function(s) of the nervous system?

• Receiving information

• Responding to information

• Maintaining homeostasis

• All of the above

The direction of impulse within a neuron always travels from:

• Dendrite to myelin

• Axon to axon terminal/tip

• Dendrite to axon terminal/tip

• Axon terminal/tip to dendrite

Which structure within a neuron allows electrical impulses to transmit quickly and efficiently along the nerve cells?

• Myelin

• Dendrite

• Axon

• Axon terminal/tip

For an impulse to move to another neuron, what must be released in the synapse?

• A mineral

• A chemical carrying impulse

• Vitamins

• Water

Look at the image and classify which neurons are A and B.

• A: interneuron - B: Motor neuron

• A: Motor neuron - B: Sensory neuron

• A: Sensory neuron - B: Motor neuron

• A: Sensory neuron - B: Interneuron
