Nervous System Quiz

It is part of the brain that is responsible for coordination, balance and of fine motor skills.

• A. Cerebrum

• B. Cerebellum

• C. Brainstem

• D. Limbic System

It is composed of complex networks of neurons that work together to send and receive signals throughout the body.

• A.   Peripheral Nervous System

• B. Sympathetic Nervous System

• C. Central Nervous System

• D. Nervous System

It is the main control center of the nervous system, responsible for processing and interpreting information.

• A. Brain

• B. Spine

• C. Heart

• D. Spinal Cord

Which part of the nervous system is most responsible for the quick reaction time of the athletes, and why?

• A. The cerebellum, because it helps control coordination and quick movements.

• B. The spinal cord, because it processes visual information and makes decisions for the body.

• C. The brainstem, because it is responsible for higher-order thinking and voluntary actions.

• D. The sympathetic nervous system, because it allows the body to rest and conserve energy.

In what ways do the brain and spinal cord work together to maintain homeostasis and coordinate body movements?

• A. The brain processes information and sends signals through the spinal cord to regulate body functions and movement.

• B. The spinal cord works independently from the brain and does not contribute to body coordination.

• C. The brain controls only thinking, while the spinal cord controls all reflexes and movements.

• D. The spinal cord sends random messages to the brain without receiving input from the body.

Why did the stroke affect the right side of the patient’s body?

• A. The right hemisphere controls the right side of the body, so any brain damage affects the same side.

• B. The left hemisphere controls the right side of the body, so damage to the left affects the right.

• C. The brain controls only voluntary movements, so involuntary actions are unaffected.

• D. The brainstem is responsible for all movement, and the cerebrum is not involved.

Why are neurons considered the basic functional units of the nervous system, and how do they communicate with each other?

• A. They transmit signals using electrical and chemical impulses across synapses.

• B. They store memories and emotions but do not send messages.

• C. They control only involuntary actions like breathing and heartbeat.

• D. They function only when a person is awake and stop working during sleep.

A doctor is testing a patient’s reflexes by tapping their knee with a small rubber hammer. The patient’s leg moves involuntarily in response to the tap. Which part of the nervous system is responsible for this automatic response?

• A. The autonomic nervous system, because it regulates digestion and breathing.

• B. The spinal cord, because it processes reflex actions without involving the brain.

• C. The cerebrum, because it controls voluntary actions.

• D. The occipital lobe, because it controls vision.

A cyclist riding on a busy road suddenly sees a car braking in front of them. In less than a second, they apply the brakes and swerve to avoid a collision. Which part of the nervous system is primarily responsible for the cyclist’s quick response?

• A. The sympathetic nervous system, because it prepares the body for action in emergencies.

• B. The parasympathetic nervous system, because it slows down the heart rate.

• C. The cerebrum, because it only controls digestion and sleep.

• D. The spinal cord, because it stores long-term memories.

A student is preparing for a big exam and feels nervous. Their heart rate increases, their palms sweat, and they feel more alert. Which division of the nervous system is responsible for these physical responses?

• A. The cerebrum, because it controls breathing and heart rate.

• B. The parasympathetic nervous system, because it keeps the body   calm.

• C. The somatic nervous system, because it controls voluntary muscle movements.

• D. The sympathetic nervous system, because it prepares the body for stress or danger.
