Exploring the Nervous System

What is the main function of the nervous system?

• The main function of the nervous system is to coordinate and control body functions and responses.

• To provide structural support to the body.

• To circulate blood throughout the body.

• To digest food and absorb nutrients.

Name the two main parts of the nervous system.

• Central nervous system and peripheral nervous system

• Cerebral cortex and spinal cord

• Autonomic nervous system and somatic nervous system

• Brain and heart

What is a neuron?

• A neuron is a hormone that regulates mood.

• A neuron is a specialized cell that transmits information in the nervous system.

• A neuron is a type of muscle cell.

• A neuron is a type of blood cell.

What does the brain do in the nervous system?

• The brain is responsible for digestion and metabolism.

• The brain acts as a sensory organ for detecting smells.

• The brain only stores memories without processing information.

• The brain serves as the control center of the nervous system, processing information and coordinating responses.

What is the spinal cord?

• The spinal cord is a vital part of the central nervous system that transmits signals between the brain and the body.

• The spinal cord is a type of bone in the spine.

• The spinal cord is a muscle that helps in movement.

• The spinal cord is an organ that filters blood.

How do nerves communicate with each other?

• Nerves communicate through synaptic transmission using neurotransmitters.

• Nerves communicate using only hormones.

• Nerves communicate by direct contact without any chemicals.

• Nerves communicate through electrical impulses only.

What is the role of sensory neurons?

• To produce hormones in response to stimuli.

• To store sensory information in the brain.

• The role of sensory neurons is to transmit sensory information from receptors to the central nervous system.

• To regulate motor functions in the body.

What is a reflex action?

• A reflex action is an automatic response to a stimulus.

• A reflex action requires conscious thought.

• A reflex action is a voluntary movement.

• A reflex action is a learned behavior.

Can the nervous system heal itself?

• Yes, but with limitations depending on the type of nervous system.

• Only the brain can heal itself, not the spinal cord.

• No, the nervous system cannot heal itself at all.

• Yes, it heals completely without any limitations.

What are some common diseases of the nervous system?

• Alzheimer's disease, Parkinson's disease, multiple sclerosis, epilepsy, and stroke.
