  • 2. 

    Which of the following are collectively called the brain stem?

    • Thalamus, hypothalamus and midbrain

    • Cerebellum, pons and medulla oblongata

    • Medulla oblongata, pons and midbrain

    • None of the above

    Correct Answer
    A. Medulla oblongata, pons and midbrain
    Explanation
    The brain stem is a part of the central nervous system that connects the brain to the spinal cord. It consists of three main structures: the medulla oblongata, the pons, and the midbrain. These structures are responsible for controlling many basic functions of the body, such as breathing, heart rate, and blood pressure. Therefore, the correct answer is "medulla oblongata, pons, and midbrain."

    Intermediate neurons are found within the

    • Central Nervous System (CNS)

    • PNS

    • Superior nervous system (SNS)

    • All of the above

    Correct Answer
    A. Central Nervous System (CNS)
    Explanation
    Intermediate neurons are found within the Central Nervous System (CNS). The CNS consists of the brain and spinal cord, and it is responsible for processing and coordinating information received from the sensory organs and sending signals to the muscles and glands. Intermediate neurons are located within the CNS and are responsible for transmitting signals between sensory and motor neurons. Therefore, the correct answer is Central Nervous System (CNS).

  • 4. 

    Which of the following coordinates muscle movements?

    • Cerebellum

    • Cerebrum

    • Cerebral hemisphere

    • All of the above

    Correct Answer
    A. Cerebellum
    Explanation
    The cerebellum is responsible for coordinating muscle movements. It receives information from the sensory systems, the spinal cord, and other parts of the brain, and uses this information to regulate and fine-tune motor activity. The cerebrum and cerebral hemisphere are not specifically responsible for coordinating muscle movements, although they do play a role in overall motor control and planning. Therefore, the correct answer is the cerebellum.

    ..................... part of the brain controls higher mental activities like reasoning?

    Correct Answer
    Frontal lobe
    Explanation
    The frontal lobe is responsible for controlling higher mental activities like reasoning. It is located at the front of the brain and plays a crucial role in decision-making, problem-solving, and critical thinking. This area also helps regulate emotions and behavior, as well as control voluntary movements. Damage to the frontal lobe can lead to difficulties in planning, judgment, and impulse control. Therefore, the frontal lobe is the correct answer for the part of the brain that controls higher mental activities.

    ......................... is an involuntary and instantaneous movement in response to the stimulus. 

    Correct Answer
    Reflex action
    Explanation
    A reflex action is an involuntary and instantaneous movement in response to a stimulus. It is an automatic response that occurs without conscious thought or decision-making. The body's nervous system is responsible for coordinating these reflex actions, which help to protect the body from harm or injury. When a stimulus is detected by sensory receptors, the information is quickly transmitted to the spinal cord or brainstem, which then sends signals to the muscles or glands to produce the appropriate reflex response. Reflex actions are essential for survival and are present in both humans and animals.

    ................. makes up the central nervous system (CNS)

    Correct Answer
    brain and spinal cord.
    Explanation
    The central nervous system (CNS) consists of the brain and spinal cord. These two components work together to process and transmit information throughout the body. The brain is responsible for controlling and coordinating various bodily functions, including thoughts, emotions, and movement. It also receives and interprets sensory information from the environment. The spinal cord serves as a pathway for communication between the brain and the rest of the body, relaying signals to and from different parts of the body. Together, the brain and spinal cord form the central control center of the nervous system.
