Understanding the Nervous System

What are the three principal functions of the nervous system?

• Sensory input, motor output, and digestion

• Sensory input, integration, and motor output

• Integration, respiration, and motor output

• Sensory input, integration, and respiration

Which part of the nervous system is responsible for processing sensory input and deciding on a response?

• Peripheral nervous system

• Central nervous system

• Autonomic nervous system

• Somatic nervous system

What is the role of the peripheral nervous system?

• It processes sensory input and decides on a response

• It communicates between the central nervous system and the rest of the body

• It controls involuntary actions like heart rate and digestion

• It is responsible for voluntary muscle movements

Which division of the peripheral nervous system picks up sensory stimuli?

• Efferent division

• Afferent division

• Somatic division

• Autonomic division

What does the efferent division of the peripheral nervous system do?

• It picks up sensory stimuli

• It sends directions from the brain to muscles and glands

• It processes sensory input

• It controls the digestive system

Which part of the nervous system is responsible for voluntary muscle movements?

• Autonomic nervous system

• Somatic nervous system

• Central nervous system

• Peripheral nervous system

What is the function of the autonomic nervous system?

• It controls voluntary muscle movements

• It processes sensory input

• It controls involuntary actions like heart rate and digestion

• It communicates between the brain and the rest of the body

Which division of the autonomic nervous system is responsible for mobilising the body into action?

• Parasympathetic division

• Sympathetic division

• Somatic division

• Afferent division

What does the parasympathetic division of the autonomic nervous system do?

• It mobilises the body into action

• It relaxes the body and conserves energy

• It controls voluntary muscle movements

• It processes sensory input
