What does integration do in the body's communication system?

• Activates effector organs

• Processes input stimuli and decides actions

• Stores information

• Transports nutrients

What is the function of motor output in the body?

• To receive sensory information

• To process stimuli

• To activate effector organs to cause a response

• To store memories

What are neurons?

• Supportive cells that provide nutrition

• Excitable cells that respond to stimuli by conducting impulses

• Cells that produce hormones

• Cells that store energy

• Conducting nerve impulses.

• Receiving signals.

• Bundling axons.

What is a ganglion?

• A bundle of axons.

• A collection of nerve cell bodies.

• A type of neuron.

• A part of the axon.

What is the role of an axon in a neuron?
