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 X-rays to create a 3D image of the inside 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 gamma rays to create a 2D image of the surface 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.

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?

  • ASensory neurons
  • BRelay neurons
  • CMotor neurons

Q6:

What is the function of the medulla oblongata?

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

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.
  • BLess active cells take in less 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.
  • DMore active cells take in more glucose, so they show up more clearly on the scan.

Q8:

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

  • ACollecting information from sensory receptors
  • BProcessing information
  • CResponding to the external environment
  • DMonitoring and regulating heart rate and breathing

Q9:

What is the function of the cerebellum?

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

Q10:

What are the main functions of the hypothalamus?

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

Q11:

What is the function of the pituitary gland?

  • ARegulating temperature and water balance
  • BControlling posture, balance, and involuntary movements
  • CProducing, storing, and releasing hormones
