Nervous System Functions

Carries nerve impulses away from the cell body.

• dendrite

• nucleus

• synapse

• axon

Carries nerve impulses toward the cell body.

• cell body

• nucleus

• dendrite

• axon

Which of the following is not a job of the nervous system?

• Restoring information

• Responding to information

• Receiving information

• Maintaining homeostasis

Nerve impulses that travel along a neuron are

• electrical

• chemical

• electrical or chemical depending on what kind of neuron

• water-soluble

In order to go from one neuron to another structure, an impulse must

• Turn into a chemical

• Turn into an electrical charge

• Be interrupted

• Stop and then start again

Type of neuron that receives information from the environment and sends an impulse to the spinal cord

• sensory neuron

• motor neuron

• spinal neuron

• motor neuron

Type of neuron that sends an impulse to a muscle or gland

• sensory neuron

• muscular neuron

• interneuron

• motor neuron

What do motor neurons do?

• send impulses to a muscle or gland

• send an impulse to the spinal cord

• detect information from our environment

• transmit messages between the spinal cord and brain
