Exploring the Nervous System

What are the main parts of the nervous system?

• Brainstem and cranial nerves

• Central nervous system (CNS) and peripheral nervous system (PNS)

• Cerebral cortex and spinal cord

• Autonomic nervous system (ANS) and somatic nervous system (SNS)

What is the function of a neuron?

• To provide structural support to tissues.

• The function of a neuron is to transmit information throughout the nervous system.

• To store memories in the brain.

• To produce hormones for the body.

What does the central nervous system consist of?

• The heart and lungs

• The stomach and intestines

• The kidneys and liver

• The brain and spinal cord

What is the role of the peripheral nervous system?

• The peripheral nervous system is responsible for memory storage.

• The peripheral nervous system connects the central nervous system to the rest of the body, facilitating communication and control.

• The peripheral nervous system only processes sensory information.

• The peripheral nervous system controls only voluntary muscle movements.

Name the two main components of the central nervous system.

• Heart and Lungs

• Kidneys and Liver

• Brain and Spinal Cord

• Stomach and Intestines

How do neurons communicate with each other?

• Neurons communicate by direct contact without any chemical signals.

• Neurons use hormones to transmit signals between each other.

• Neurons communicate through electrical impulses only.

• Neurons communicate via synaptic transmission using neurotransmitters.

What is the function of the brain?

• The brain produces hormones that regulate digestion.

• The brain stores all memories permanently without any processing.

• The brain is responsible for breathing and heart rate only.

• The brain controls and coordinates body functions and processes information.

What is the spinal cord responsible for?

• Regulating blood flow in the heart

• Producing hormones for digestion

• Filtering toxins from the blood

• Transmitting signals between the brain and body, coordinating reflexes.

How does the peripheral nervous system connect to the central nervous system?

• The peripheral nervous system communicates with the central nervous system only during sleep.

• The peripheral nervous system connects to the central nervous system through blood vessels.

• The peripheral nervous system operates independently of the central nervous system.

• The peripheral nervous system connects to the central nervous system via nerves and the spinal cord.

What are sensory neurons and what do they do?

• Sensory neurons are involved in hormone production.

• Sensory neurons transmit signals from the brain to the muscles.

• Sensory neurons are nerve cells that carry sensory information from receptors to the central nervous system.

• Sensory neurons are responsible for motor control.
