Understanding the Nervous System

What are the two main components of the nervous system?

• Central and Peripheral Nervous Systems

• Spinal Cord and Muscles

• Sensory and Motor Neurons

• Brain and Heart

Which type of neuron is responsible for carrying signals from receptors to the central nervous system?

• Relay Neurons

• Sensory Neurons

• Motor Neurons

• Interneurons

What is the role of neurotransmitters in the nervous system?

• They protect neurons from damage.

• They bridge the gap between neurons at synapses.

• They generate electrical impulses.

• They store information in the brain.

Why are reflex actions important for the body?

• They help in voluntary movements.

• They allow the brain to rest.

• They protect the body from potential harm.

• They enhance memory retention.

In a reflex arc, which part of the nervous system is bypassed to ensure a quick response?

• Spinal Cord

• Brain

• Sensory Neurons

• Motor Neurons
