A Trivia Quiz On Neuroanatomy! - Quiz

What do you know about neuroanatomy? Neuroanatomy is the research of the structure and purpose of the nervous system. The nervous system is derived from numerous connected systems that work synergistically to send and receive messages from the central nervous system, which consists of the brain, the spinal cord, and the whole human body. The quiz will reveal what you know about neuroanatomy.


Questions and Answers
  • 1. 

    Which of the following terms do NOT belong with the others?

    • A.

      Frontal

    • B.

      Sagittal

    • C.

      Horizontal

    • D.

      Transverse

    • E.

      Rostral

    Correct Answer
    E. Rostral
    Explanation
    The terms frontal, sagittal, horizontal, and transverse all relate to different planes or directions in the body. However, rostral refers specifically to a direction towards the front of the head or brain. It does not belong with the others because it is a term that is specific to the head or brain, whereas the others are more general terms related to different planes or directions in the body.

    Rate this question:

  • 2. 

    Caudal is to rostral as

    • A.

      Contralateral is to antagonistic

    • B.

      Medial is to superior

    • C.

      Inferior is to lateral

    • D.

      Lateral is to anterior

    • E.

      Posterior is to anterior

    Correct Answer
    E. Posterior is to anterior
    Explanation
    The relationship between caudal and rostral is that they are opposite directions along the body axis. Caudal refers to the tail end or the direction towards the tail, while rostral refers to the head end or the direction towards the head. Similarly, the relationship between posterior and anterior is that they are opposite directions along the body axis. Posterior refers to the back end or the direction towards the back, while anterior refers to the front end or the direction towards the front.

  • 3. 

    A ___________ sections made through a human brain divides the brain like a salami.

    • A.

      Transverse

    • B.

      Horizontal

    • C.

      Sagittal

    • D.

      Frontal

    • E.

      A and D are correct

    Correct Answer
    E. A and D are correct
    Explanation
    The correct answer is A and D because both the transverse and frontal sections divide the brain in a way that resembles a salami being sliced. A transverse section is a horizontal cut made across the brain, while a frontal section is a cut made from front to back, dividing the brain into front and back portions. Both of these sections divide the brain in a way that resembles the slicing of a salami.

    Rate this question:

  • 4. 

    The ________ is comprised of the brain and the spinal cord.

    • A.

      Peripheral nervous system.

    • B.

      Central nervous system.

    • C.

      Enteric nervous system.

    • D.

      Brainstem

    • E.

      Forebrain

    Correct Answer
    B. Central nervous system.
    Explanation
    The correct answer is central nervous system. The central nervous system consists of the brain and the spinal cord. It is responsible for processing and coordinating information received from the peripheral nervous system and sending out instructions to the rest of the body. The brain controls higher cognitive functions, while the spinal cord serves as a pathway for transmitting signals between the brain and the body. The central nervous system plays a crucial role in regulating bodily functions and behaviors.

  • 5. 

    Which of the following terms do NOT belong with the others?

    • A.

      Frontal

    • B.

      Sagittal

    • C.

      Horizontal

    • D.

      Transverse

    • E.

      Rostral

    Correct Answer
    E. Rostral
    Explanation
    The terms frontal, sagittal, horizontal, and transverse all refer to different anatomical planes or directions. They are all related to the orientation or position of the body or body parts. However, rostral refers specifically to a direction towards the front of the head or brain. It is not a term that is used to describe the orientation or position of the body as a whole. Therefore, rostral does not belong with the others.

    Rate this question:

  • 6. 

    The ______ interconnects the third and fourth ventricles.

    • A.

      Choroid plexus

    • B.

      Subarachnoid space

    • C.

      Corpus callosum

    • D.

      Arachnoid granulations

    • E.

      Cerebral aqueduct

    Correct Answer
    E. Cerebral aqueduct
    Explanation
    The cerebral aqueduct is a narrow channel that connects the third and fourth ventricles of the brain. It allows for the flow of cerebrospinal fluid between these two ventricles, helping to maintain the balance and circulation of this fluid within the brain.

    Rate this question:

  • 7. 

    What is an experimental advantage provided by the architecture of the ventricular system?

    • A.

      Drugs can be infused into the ventricles to reach brain regions protected by the blood-brain barrier.

    • B.

      The ventricles lie outside the blood-brain barrier.

    • C.

      Drugs infused into the gut are rapidly transferred to the ventricles.

    • D.

      Blockade of the ventricular CSF rapidly impairs brain function.

    • E.

      C and D are correct.

    Correct Answer
    A. Drugs can be infused into the ventricles to reach brain regions protected by the blood-brain barrier.
    Explanation
    The architecture of the ventricular system provides an experimental advantage by allowing drugs to be infused directly into the ventricles. This is beneficial because it allows the drugs to reach brain regions that are protected by the blood-brain barrier, which would otherwise prevent the drugs from entering the brain. This method bypasses the barrier and provides a direct route for drug delivery to specific brain regions.

  • 8. 

    On the 28th day of embryonic development the human brain most resembles

    • A.

      A hollow tube.

    • B.

      A shallow plate.

    • C.

      A series of ridges.

    • D.

      A series of increasingly larger rectangles.

    • E.

      The shape of a fried egg.

    Correct Answer
    A. A hollow tube.
    Explanation
    During the 28th day of embryonic development, the human brain is in the early stages of forming. At this point, it appears as a hollow tube, which is the closest shape among the options provided. As the development progresses, the brain will undergo further changes and eventually take on its final structure.

  • 9. 

    Electrical stimulation of the right motor cortex elicits limb movements on the left side of the body and vice versa. Which term below best describes these organizations of the motor cortex and the muscles of the body?

    • A.

      Contralateral

    • B.

      Horizontal

    • C.

      Ipsilateral

    • D.

      Antagonistic

    • E.

      Parasagittal

    Correct Answer
    A. Contralateral
    Explanation
    Electrical stimulation of the motor cortex causes limb movements on the opposite side of the body, indicating a contralateral organization. This means that the motor cortex controls movements on the opposite side of the body.

    Rate this question:

  • 10. 

    H.M. was not able to learn anything new.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement "H.M. was not able to learn anything new" is false. H.M. was a patient who underwent brain surgery to treat his epilepsy, which resulted in severe anterograde amnesia. However, despite his inability to form new long-term memories, H.M. was able to learn new skills and tasks through repetition and procedural memory. This suggests that while he couldn't consciously recall new information, his brain was still capable of learning and retaining certain types of knowledge.
