Exploring the Nervous System

Explain the difference between the central and peripheral nervous systems.

• The central nervous system processes information, while the peripheral nervous system connects the CNS to the rest of the body.

• The central nervous system is responsible for reflex actions, while the peripheral nervous system controls voluntary movements.

• The central nervous system is located outside the skull, while the peripheral nervous system is located inside the skull.

• The central nervous system includes the spinal cord only, while the peripheral nervous system includes the brain.

Describe the symptoms of multiple sclerosis.

• Severe headaches and migraines

• Skin rashes and allergies

• Frequent colds and flu-like symptoms

• Symptoms of multiple sclerosis include fatigue, difficulty walking, numbness or tingling, muscle weakness, vision problems, and cognitive changes.

Which part of the brain controls balance and coordination?

• cerebrum

• cerebellum

• medulla

Which part of the brain controls senses, thinking, and memory?

• cerebrum

• cerebellum

• medulla

What is the role of the peripheral nervous system in reflex actions?

• The peripheral nervous system transmits sensory and motor signals that facilitate reflex actions.

• The peripheral nervous system is responsible for higher cognitive functions.

• The peripheral nervous system only processes visual information.

• The peripheral nervous system does not play a role in reflex actions.

What are the three parts of the nervous system?

• brain, spinal cord, nerves

• brain, lungs, spinal cord

• heart, brain, nerves

• brain, nerves, neurons

What are the two divisions of the nervous system?

• Central and Lower nervous systems

• Central and Peripheral nervous systems

• Lower and Cerebral nervous systems

• Central and Muscular nervous systems

What is the function of the hypothalamus?

• The hypothalamus controls vision and hearing.

• The hypothalamus is responsible for muscle coordination.

• The hypothalamus regulates blood pressure and heart rate.

• The hypothalamus regulates homeostasis, including temperature, hunger, thirst, sleep, and hormonal balance.

Explain how the nervous system responds to stimuli.

• The nervous system only reacts to pain stimuli.

• The nervous system does not involve sensory neurons in its response.

• The nervous system responds by only sending signals to the brain.

• The nervous system responds to stimuli by detecting, processing, and executing appropriate responses through sensory and motor neurons.

When the spinal cord responds in an emergency to a stimulus before the brain, this is called a...

• synapse

• cerebral response

• reflex
