Division of Nervous System Quiz

What are the two main parts of the central nervous system?

• brain and spinal cord

• kidneys and bladder

• stomach and liver

• heart and lungs

Explain the function of the spinal cord in the nervous system.

• The spinal cord is responsible for producing hormones in the body.

• The spinal cord is involved in regulating body temperature.

• The spinal cord acts as a pathway for nerve signals and is involved in reflex actions.

• The spinal cord helps in digestion and absorption of nutrients.

How does the brain control the body's voluntary movements?

• Motor cortex sends signals to the muscles

• The heart controls voluntary movements

• The liver sends signals to the muscles

• The lungs are responsible for voluntary movements

What is the role of the sensory afferent division of the nervous system?

• Regulate body temperature

• Control voluntary muscle movements

• Produce hormones

• Transmit sensory information to the central nervous system

Describe the process of sensory reception and transmission in the nervous system.

• Sensory reception involves the production of hormones by the endocrine system.

• Sensory transmission is carried out by motor neurons.

• The central nervous system detects stimuli through sensory receptors.

• Sensory reception involves the detection of stimuli by sensory receptors, which then transmit the information to the central nervous system through sensory neurons.

What is the difference between somatic and autonomic motor division of the nervous system?

• Voluntary control of skeletal muscles vs. involuntary control of smooth muscles, cardiac muscles, and glands

• Involuntary control of skeletal muscles vs. voluntary control of smooth muscles

• Conscious control of heart rate vs. unconscious control of muscle movement

• Control of sensory neurons vs. control of motor neurons

Explain the role of the motor division in the fight or flight response.

• Activates the fight or flight response by stimulating the release of adrenaline and increasing heart rate, blood pressure, and breathing rate.

• Inhibits the release of adrenaline and decreases heart rate, blood pressure, and breathing rate

• Has no role in the fight or flight response

• Causes relaxation and calmness in response to stress

What are the two main types of neurons in the motor division of the nervous system?

• Left motor neurons and right motor neurons

• Upper motor neurons and lower motor neurons

• Sensory neurons and interneurons

• Brain neurons and spinal neurons

How does the motor division of the nervous system control involuntary actions?

• Through the endocrine system

• Through the central nervous system

• Through the somatic nervous system

• Through the autonomic nervous system

Describe the role of the parasympathetic division in the nervous system.

• It increases heart rate and blood pressure.

• It stimulates the fight or flight response.

• It is responsible for muscle relaxation and energy conservation.

• It promotes relaxation and conserves energy.
