Worksheet: The Brain

In this worksheet, we will practice identifying regions of the brain, describing their functions and explaining how to investigate brain function.

Q1:

Which of the following statements best describes how a CT scan can be used to investigate brain function?

  • AA CT scan uses gamma rays to create a 2D image of the surface of the body.
  • BA CT scan uses microwaves to create a 3D image of the inside of the body.
  • CA CT scan uses gamma rays to create a 3D image of the inside of the body.
  • DA CT scan uses X-rays to create a 3D image of the inside of the body.
  • EA CT scan uses X-rays to create a 2D image of the surface of the body.

Q2:

Spinal cord injuries are often permanent because there are no stem cells in the spinal cord to replace damaged cells.

Is this statement true or false?

  • ATrue
  • BFalse

Q3:

A person with ataxia walks with jerky and uncoordinated movements.

  • APituitary gland
  • BCerebellum
  • CHypothalamus
  • DCerebrum
  • EMedulla oblongata

After suffering a stroke, a person may struggle to remember key events.

  • AHypothalamus
  • BCerebrum
  • CPituitary gland
  • DCerebellum
  • EMedulla oblongata

After falling from a motorbike, a rider’s heart rate increases rapidly and they struggle to breathe normally.

  • AHypothalamus
  • BCerebrum
  • CPituitary gland
  • DMedulla oblongata
  • ECerebellum

After developing a brain tumour, a patient finds they sweat in cold rooms and need to urinate more.

  • AMedulla oblongata
  • BCerebrum
  • CHypothalamus
  • DPituitary gland
  • ECerebellum

Q4:

Which of the following statements best describes how MRI scanners can be used to investigate brain functions?

  • AMRI scanners use electrical impulses to visualize activity in different parts of the brain.
  • BMRI scanners take 2D pictures of the inside of the body to show activity.
  • CMRI scanners use powerful magnets to visualize activity in different parts of the brain.
  • DMRI scanners use X-rays to visualize activity in different parts of the brain.

Q5:

Your brain transmits electrical impulses to coordinate responses. To what neurons does the brain send impulses to bring about a response?

  • AMotor neurons
  • BRelay neurons
  • CSensory neurons

Q6:

What is the function of the medulla oblongata?

  • ATo store and release hormones
  • BTo control heart and breathing rates
  • CTo regulate temperature and water balance
  • DTo control posture, balance, and involuntary movements
  • ETo control complex behavior like learning, memory, and conscious thought

Q7:

A PET scan involves injecting radioactive glucose into a patient. Which of the following is correct about cells in the brain?

  • AMore active cells take in less glucose, so they show up more clearly on the scan.
  • BMore active cells take in more glucose, so they show up more clearly on the scan.
  • CLess active cells take in more glucose, so they show up clearly on the scan.
  • DLess active cells take in less glucose, so they show up more clearly on the scan.

Q8:

Which of the following is not a function of the brain?

  • ACoordinating responses involved in reflex actions
  • BCollecting information from sensory receptors
  • CMonitoring and regulating heart rate and breathing
  • DProcessing information
  • EResponding to the external environment

Q9:

What is the function of the cerebellum?

  • ATo store and release hormones
  • BTo regulate temperature and water balance
  • CTo control posture, balance, and voluntary movements
  • DTo control complex behavior like learning, memory, and conscious thought
  • ETo control heart and breathing rates

Q10:

What are the main functions of the hypothalamus?

  • ATo regulate reflex actions
  • BTo control posture, balance, and involuntary movements
  • CTo control heart and breathing rates
  • DTo control complex behavior like learning, memory, and conscious thought
  • ETo regulate temperature and water balance

Q11:

What is the function of the pituitary gland?

  • AProducing, storing, and releasing hormones
  • BControlling posture, balance, and involuntary movements
  • CControlling heart and breathing rates
  • DRegulating temperature and water balance
  • EControlling complex behavior like learning, memory, and thought

  • BControlling heart and breathing rates
  • CStoring and releasing hormones
  • DRegulating temperature and water balance
  • EControlling posture, balance, and involuntary movements
