Nervous System Quiz

Which structures make up the central nervous system?

• Brain and spinal cord

• Brain and autonomic nervous system

• Somatic and autonomic nervous systems

• Spinal cord and peripheral nervous system

What is the main role of the spinal cord?

• To regulate hormones

• To transmit information between brain and body

• To detect sensory stimuli

• To produce neurotransmitters

Which part of the brain is primarily responsible for higher mental functions such as reasoning and planning?

• Cerebellum

• Brain stem

• Cerebral cortex

• Hypothalamus

The cerebellum is most closely linked to:

• Memory storage

• Balance and coordination

• Hormone release

• Emotional processing

Damage to the medulla is most likely to affect:

• Voluntary muscle movement

• Breathing and heart rate

• Long-term memory

• Language production

Which two main divisions make up the peripheral nervous system?

• Autonomic and parasympathetic

• Somatic and autonomic

• Central and spinal

• Sympathetic and motor

The somatic nervous system is responsible for:

• Reflex actions and involuntary processes

• Voluntary movement and sensory information

• Fight or flight responses

• Digestive regulation

What is the main role of sensory neurons in the PNS?

• Carry messages from brain to muscles

• Carry messages from sense organs to CNS

• Produce neurotransmitters

• Control automatic processes

A reflex arc occurs when:

• The brain consciously decides how to respond

• The spinal cord coordinates a rapid, automatic response

• The hypothalamus triggers hormonal release

• The sympathetic system activates digestion

The peripheral nervous system links the CNS to:

• Only muscles

• Only glands

• The rest of the body (organs, muscles, glands)

• The cerebral cortex
