What Do You Know About Your Brain? - Quiz

The brain is an essential organ located in the skull. The brain is divided into parts which control body systems like homeostasis. This central organ works together with the spinal cord to make up the central nervous system. Having numerous veins, arteries and bi-system function show its importance, protected by skull bones of the head.


Questions and Answers
  • 1. 

    Which of these is the biggest part of the human brain? 

    • A. 

      Cerebrum 

    • B. 

      Cerebellum 

    • C. 

      Brain Stem 

    • D. 

      Hypothalamus 

    Correct Answer
    A. Cerebrum 
    Explanation
    The cerebrum is the largest part of the human brain. It is responsible for higher cognitive functions such as thinking, memory, and language. It is divided into two hemispheres and is composed of various lobes, including the frontal, parietal, temporal, and occipital lobes. The cerebrum plays a crucial role in controlling voluntary movements and interpreting sensory information. Additionally, it is involved in emotions, problem-solving, decision-making, and creativity.

    Which part of the brain controls homeostasis? 

    • A. 

      Pons 

    • B. 

      Cerebellum 

    • C. 

      Hypothalamus 

    • D. 

      Cerebrum 

    Correct Answer
    C. Hypothalamus 
    Explanation
    The hypothalamus is responsible for controlling homeostasis in the body. It regulates various bodily functions such as body temperature, hunger and thirst, sleep, and hormone production. It receives signals from the body and adjusts these functions to maintain a stable internal environment. The pons is involved in regulating sleep and respiration, while the cerebellum is responsible for coordinating movement and balance. The cerebrum is involved in higher cognitive functions such as thinking and problem-solving. Therefore, the correct answer is the hypothalamus.

    Which part of the brain does medulla oblongata belongs? 

    • A. 

      Forebrain 

    • B. 

      Hindbrain

    • C. 

      Midbrain

    • D. 

      Central brain 

    Correct Answer
    C. Midbrain
    Explanation
    The medulla oblongata is a part of the hindbrain, which is responsible for regulating vital functions such as breathing, heart rate, and blood pressure. It is located at the base of the brainstem, connecting the spinal cord to the rest of the brain. The midbrain, on the other hand, is responsible for relaying sensory and motor information and is located above the hindbrain. Therefore, the correct answer is hindbrain.

    What connects cerebrum to the spinal cord? 

    • A. 

      Brain stem 

    • B. 

      Cerebellum 

    • C. 

      Pons 

    • D. 

      Hypothalamus 

    Correct Answer
    A. Brain stem 
    Explanation
    The brain stem is the part of the brain that connects the cerebrum to the spinal cord. It is responsible for controlling basic functions such as breathing, heart rate, and blood pressure. It also serves as a pathway for nerve signals to travel between the brain and the rest of the body. The cerebellum, pons, and hypothalamus are all important parts of the brain, but they do not directly connect the cerebrum to the spinal cord.

    What of the following is the brain cell? 

    • A. 

      Nephron 

    • B. 

      Neuron 

    • C. 

      Neutron 

    • D. 

      Heparin 

    Correct Answer
    B. Neuron 
    Explanation
    A neuron is the correct answer because it is a specialized cell in the brain and nervous system that transmits information through electrical and chemical signals. Neurons are responsible for processing and transmitting information, allowing for communication between different parts of the body and facilitating various functions such as movement, sensation, and cognition.

    Which of these body systems belongs to the brain? 

    • A. 

      Transport system 

    • B. 

      Circulatory system 

    • C. 

      Nervous system 

    • D. 

      Digestive system 

    Correct Answer
    C. Nervous system 
    Explanation
    The brain belongs to the nervous system. The nervous system is responsible for transmitting signals throughout the body, including the brain. It controls and coordinates all bodily functions and processes, allowing us to think, move, feel, and react to our environment. The brain is the central organ of the nervous system and is responsible for processing and interpreting information received from the body and the external world.

    Which of these is a brain damage? 

    • A. 

      Stroke 

    • B. 

      Dropsy 

    • C. 

      Hepatitis 

    • D. 

      Diuresis

    Correct Answer
    A. Stroke 
    Explanation
    A stroke is a type of brain damage that occurs when the blood supply to the brain is interrupted, either by a blockage or a rupture of a blood vessel. This interruption prevents oxygen and nutrients from reaching the brain, leading to the death of brain cells. Strokes can cause various symptoms depending on the area of the brain affected and can result in long-term disability or even death.

    How many arteries does brain have? 

    • A. 

      2

    • B. 

      4

    • C. 

      3

    • D. 

      1

    Correct Answer
    A. 2
    Explanation
    The brain has two main arteries: the left and right internal carotid arteries. These arteries supply blood to the brain, delivering oxygen and nutrients necessary for its proper functioning.

    Which of these is not a part of the brain? 

    • A. 

      Cerebrum 

    • B. 

      Medulla Oblongata 

    • C. 

      Pons

    • D. 

      Nerve 

    Correct Answer
    D. Nerve 
    Explanation
    The cerebrum, medulla oblongata, and pons are all parts of the brain. However, a nerve is not a part of the brain. Nerves are part of the peripheral nervous system, which includes the nerves outside of the brain and spinal cord. The brain itself is composed of different regions, including the cerebrum, medulla oblongata, and pons, which are responsible for various functions such as cognition, coordination, and regulation of vital functions.

    What is a brains precursor? 

    • A. 

      Neuron 

    • B. 

      Cardio 

    • C. 

      Neural tube 

    • D. 

      Neural plates 

    Correct Answer
    C. Neural tube 
    Explanation
    A brain's precursor refers to the structure that develops before the brain itself. In the early stages of embryonic development, the neural tube forms, which eventually gives rise to the entire central nervous system, including the brain and spinal cord. Therefore, the correct answer is "Neural tube."
