Nervous System Quiz

What are the two main parts of the nervous system?

• Central nervous system and digestive system

• Central nervous system and peripheral nervous system

• Peripheral nervous system and circulatory system

• Digestive system and circulatory system

What does the Central Nervous System (CNS) include?

• The brain and spinal cord

• The heart and lungs

• The stomach and intestines

• The muscles and bones

Which part of the Peripheral Nervous System (PNS) is under conscious control?

• Autonomic nervous system

• Somatic nervous system

• Central nervous system

• Digestive system

What is the function of the autonomic nervous system?

• Controls voluntary actions

• Controls involuntary actions

• Processes sensory information

• Regulates muscle movement

What is the role of sensory or afferent nerve fibers in the peripheral nervous system?

• They carry information from the CNS to target tissues and organs.

• They collect information from the environment and transmit it to the CNS.

• They are responsible for voluntary muscle movements.

• They regulate the autonomic nervous system.

Which type of nerves are responsible for carrying information from the CNS to target tissues and organs?

• Cranial nerves

• Sensory or afferent nerve fibers

• Motor or efferent nerve fibers

• Spinal nerves

Which of the following is NOT a part of the peripheral nervous system?

• Cranial nerves

• Spinal nerves

• Sensory nerve fibers

• Brain

What is the primary function of motor nerves (efferent)?

• Transmit signals from the brain to muscles and glands

• Carry signals to the brain from the rest of the body

• Transmit signals between neurons

• Carry signals from the spinal cord to the brain

What is the primary function of sensory nerves (afferent)?

• Transmit signals from the brain to muscles and glands

• Carry signals to the brain from the rest of the body

• Transmit signals between neurons

• Carry signals from the spinal cord to the brain

Which statement is true about the pairing of motor and sensory nerves?

• All sensory nerves have a paired motor nerve.

• All motor nerves have a paired sensory nerve.

• Motor and sensory nerves never run alongside each other.

• All motor nerves are independent of sensory nerves.
