Anatomy NS Intro Review

What are the main components of the Central Nervous System (CNS)?

• Brain and Spinal Cord

• Cranial nerves and branches

• Spinal nerves and branches

• Neurons and ganglia

What is the primary function of the Central Nervous System (CNS)?

• Transport sensory input

• Integration and interpretation of sensory input

• Control of cranial nerves

• Production of hormones

Which part of the nervous system includes cranial nerves and branches?

• Central Nervous System (CNS)

• Peripheral Nervous System (PNS)

• Autonomic Nervous System

• Sympathetic Nervous System

What role do neurons in the Peripheral Nervous System (PNS) play?

• Dictate motor response

• Transport sensory input toward CNS and motor output away from CNS

• Produce neurotransmitters

• Control reflex actions

What is the role of sensory receptors in the nervous system?

• To initiate and activate motor responses

• To monitor internal and external changes

• To process information from multiple receptors

• To dictate a response

What is the function of interneurons in the nervous system?

• To carry sensory information to muscles

• To monitor external changes

• To process sensory input and activate motor output

• To initiate motor responses

What happens during the integration of information in the nervous system?

• Sensory receptors monitor changes

• Motor responses are initiated

• Information from multiple receptors is processed and a response is dictated

• Muscles are activated

What is the final step in the nervous system's response to stimuli?

• Sensory input

• Integration of information

• Motor output

• Interneuron processing

What happens during the sensory input stage when a fly lands on your arm?

• Neurons in the brain are activated.

• Muscles in your arm contract.

• Neurons wrapped around the hair root are activated.

• The fly is brushed off immediately.

What is the role of integration in the nervous system response to a fly landing on your arm?

• It causes the muscles to contract.

• It activates neurons in the brain.

• It directly brushes off the fly.

• It wraps neurons around the hair root.
