  • 2. 

    ___________ is the control center of body

    Explanation
    The brain is the control center of the body because it is responsible for coordinating and regulating all bodily functions. It receives and processes information from the senses, controls movement, regulates body temperature, and allows for complex cognitive processes such as thinking, memory, and emotions. Without the brain, the body would not be able to function properly or survive.

    • True

    • False

    A. True
    Explanation
    The statement "our spinal cord is like a wire" is true. The spinal cord is a long, thin, tubular bundle of nerves that extends from the base of the brain down the back. It serves as a pathway for signals between the brain and the rest of the body, similar to how a wire transmits electrical signals. The comparison highlights the structural and functional role of the spinal cord in facilitating communication within the nervous system.

    Explanation
    The cerebrum is the largest part of the brain. It is responsible for many functions including conscious thought, memory, language, and sensory perception. It is divided into two hemispheres and is highly folded, allowing for a greater surface area and more complex cognitive abilities. The cerebrum plays a crucial role in higher-order thinking and is involved in coordinating and controlling voluntary movements.

    Correct Answer
    sensory
    Explanation
    A sensory nerve is responsible for transmitting messages from the sense organs to the central nervous system. It carries information about sensory experiences such as touch, temperature, pain, and pressure from the body's sensory receptors to the brain. This allows us to perceive and interpret the world around us.
