Lesson Worksheet: The Autonomic Nervous System Biology

In this worksheet, we will practice describing the structure and function of the sympathetic and parasympathetic nervous systems.

Q1:

Which of the following organs does not receive nerve supply from the brain stem?

  • ALiver
  • BPancreas
  • CAdrenal gland
  • DSalivary gland

Q2:

Which of the following is not a function controlled by nerve fibres from the brain stem?

  • AIncreasing salivary secretion
  • BIncreasing heartbeats
  • CIncreasing gastric secretion
  • DDecreasing glucose level in the blood

Q3:

Complete the following statement:

When doing a physical exercise, the heart rate increases, blood supply to the digestive system decreases, blood vessels feeding the muscles dilate, bronchioles dilate, and sweat glands are activated. These changes are due to the actions of .

  • Athe parasympathetic nervous system
  • Bthe sympathetic nervous system
  • Cboth the sympathetic and the parasympathetic nervous systems
  • Dthe central nervous system

Q4:

When someone eats a meal, which part of the nervous system acts on the components of the digestive system?

  • AThe sympathetic system
  • BThe parasympathetic system
  • CThe central nervous system
  • DThe reflex arc system

Q5:

When facing a threatening situation, either real or imagined, the body increases the heartbeat and respiration rate to provide the body with the required amount of energy. Which of the following best describes how the body’s response to danger affects the digestive process?

  • AThe parasympathetic nervous system inhibits digestion so that all the energy can be focused to face the possible danger.
  • BThe parasympathetic nervous system stimulates digestion to release the required amount of energy from digested food.
  • CThe sympathetic nervous system stimulates digestion to release the required amount of energy from digested food.
  • DThe sympathetic nervous system inhibits digestion so that all the energy can be focused to face the possible danger.

Q6:

The peripheral nerves that feed the urinary bladder arise from of the spinal cord.

  • Athe thoracic and lumbar regions
  • Bthe lumbar and sacral regions
  • Cthe thoracic, lumbar, and sacral regions
  • Dthe brain stem and sacral region

Q7:

A person is walking on a pavement when suddenly he sees a car speeding towards him. Which of the following would not be a response triggered by the autonomic nervous system in that situation?

  • AVasodilating blood vessels which supply the skeletal muscles
  • BIncreasing heart rate
  • CContracting stomach wall
  • DDilating bronchioles
  • ERelaxing urinary bladder

Q8:

Which of the following is a response brought about by the parasympathetic nervous system?

  • AThe dilation of pupils
  • BAn increase in blood glucose
  • CA decrease in the secretion of digestive enzymes
  • DA decrease in heart rate

Q9:

The table provided shows the effect of the parasympathetic and the sympathetic nervous systems on some major organs and glands.

Organ/Gland Affected Effect of Parasympathetic Nervous SystemEffect of Sympathetic Nervous System
Blood vesselsDilation of blood vessels supplying the digestive systemDilation of blood vessels supplying skeletal muscles
Eye
Adrenal medullaInhibitedActivated

What effect does the sympathetic nervous system have on the pupils?

  • AIt constricts the pupils.
  • BIt dilates the pupils.
  • CThe pupils are not affected.

Q10:

What is the primary purpose of the autonomic nervous system?

  • ATo control voluntary movements and coordination
  • BTo regulate involuntary activities
  • CTo initiate the fight or flight response
  • DTo transmit information from the brain to the rest of the body
