Your Brain Question And Answer Quiz - Quiz

You wonder how are able to recollect seemingly complex details, do great multitasking, hear melodious music, feel the warmth of summer? Your brain is always at work. It is the center of the nervous system. It is the most complex structure in the body. You already know that? Assess your knowledge with this quiz.


Questions and Answers
  • 1. 

    Neurons communicate with one another through long protoplasmic fibers called ______________

    • A. 

      Arteries

    • B. 

      Axons

    • C. 

      Furrows

    • D. 

      Nucleus

    Correct Answer
    B. Axons
    Explanation
    Neurons communicate with one another through long protoplasmic fibers called axons. Axons are responsible for transmitting electrical impulses and information from one neuron to another, allowing for the exchange of signals and communication within the nervous system. Unlike arteries, which are blood vessels that transport oxygenated blood, furrows, which are shallow grooves, and the nucleus, which is the central part of a cell, axons are specifically designed for neuronal communication.

    Which of these is not a fungi of glial cells?

    • A. 

      Coordination of impulses

    • B. 

      Metabolic support

    • C. 

      Structural support

    • D. 

      Insulation

    Correct Answer
    A. Coordination of impulses
    Explanation
    Coordination of impulses is not a function of glial cells. Glial cells, also known as neuroglia, are non-neuronal cells that provide support and protection to neurons in the central nervous system. They play a crucial role in metabolic support, structural support, and insulation of neurons. However, the coordination of impulses is primarily carried out by neurons, not glial cells. Neurons are responsible for transmitting and coordinating electrical signals in the nervous system.

    What part of the brain concerned with intelligence?

    • A. 

      Brainstem

    • B. 

      Hypothalamus

    • C. 

      Cerebellum

    • D. 

      Cerebrum

    Correct Answer
    D. Cerebrum
    Explanation
    The cerebrum is the part of the brain that is concerned with intelligence. It is responsible for higher cognitive functions such as thinking, reasoning, problem-solving, and memory. It is the largest and most developed part of the brain, consisting of two hemispheres that are responsible for different functions. The cerebrum plays a crucial role in intelligence as it processes sensory information, integrates it with past experiences, and allows for complex cognitive processes to occur.

  • 4. 

    What part of the brain coordinates endocrine functions?

    • A. 

      Brainstem

    • B. 

      Hypothalamus

    • C. 

      Thalamus

    • D. 

      Cerebellum

    Correct Answer
    B. Hypothalamus
    Explanation
    The hypothalamus is responsible for coordinating endocrine functions in the brain. It acts as a link between the nervous system and the endocrine system, regulating hormone production and release from the pituitary gland. It controls various bodily functions such as body temperature, hunger, thirst, and sleep, through the release of hormones. The hypothalamus plays a crucial role in maintaining homeostasis and overall hormonal balance in the body.

  • 5. 

    Concerning the development of the brain, which of these is odd?

    • A. 

      Rhombencephalon

    • B. 

      Mesencephalon

    • C. 

      Prosencephalon

    • D. 

      Archiosencephalon

    Correct Answer
    D. Archiosencephalon
    Explanation
    The correct answer is Archiosencephalon. The other options (rhombencephalon, mesencephalon, and prosencephalon) are all parts of the embryonic brain. The archiosencephalon is not a recognized term in the field of neuroscience or developmental biology.

  • 6. 

    The connective tissue membranes that surround the brain are called _________

    • A. 

      Spheres

    • B. 

      Meninges

    • C. 

      Bundles

    • D. 

      Furrows

    Correct Answer
    B. Meninges
    Explanation
    The connective tissue membranes that surround the brain are called meninges. These membranes provide protection and support to the brain and spinal cord. The meninges consist of three layers: the dura mater, the arachnoid mater, and the pia mater. They help cushion the brain from impact, contain cerebrospinal fluid, and provide a barrier against infections.

  • 7. 

    Which of these is not a function of medulla?

    • A. 

      Control of vomiting

    • B. 

      Control of sneezing

    • C. 

      Control of heartbeat

    • D. 

      Control of digestion

    Correct Answer
    B. Control of sneezing
    Explanation
    The medulla is responsible for controlling various involuntary functions in the body, such as vomiting, heartbeat, and digestion. However, sneezing is not directly controlled by the medulla. Sneezing is a reflex action triggered by irritation in the nasal passages, and it is controlled by the trigeminal nerve.

  • 8. 

    The part of the brain found only in mammals is the  _______  

    • A. 

      Basal ganglia

    • B. 

      Hypothalamus

    • C. 

      Medulla oblongata

    • D. 

      Pons

    Correct Answer
    D. Pons
    Explanation
    The pons is a part of the brainstem that is found only in mammals. It is responsible for relaying signals between the cerebrum and the cerebellum, as well as controlling various autonomic functions such as breathing and sleeping. The basal ganglia, hypothalamus, and medulla oblongata are all also parts of the brain, but they are not exclusive to mammals.

    The olfactory bulb helps us to _______

    • A. 

      Feel cold 

    • B. 

      Balance and walk normally

    • C. 

      Perceive odors

    • D. 

      Hear

    Correct Answer
    C. Perceive odors
    Explanation
    The olfactory bulb is responsible for our sense of smell, so it helps us perceive odors. It receives signals from the olfactory receptors in our nose and sends them to the brain for interpretation. Without the olfactory bulb, we would not be able to detect and identify different smells in our environment.

    The doctor who treats diseases of the brain is called a ________

    • A. 

      Ophthalmologist

    • B. 

      Neurologist

    • C. 

      Endocrinologist

    • D. 

      Rheumatologist

    Correct Answer
    B. Neurologist
    Explanation
    A neurologist is a doctor who specializes in treating diseases and disorders of the brain and nervous system. They are trained to diagnose and treat conditions such as epilepsy, stroke, multiple sclerosis, Alzheimer's disease, and Parkinson's disease. They often work closely with other specialists, such as neurosurgeons and psychiatrists, to provide comprehensive care for patients with neurological conditions.
