  • 2. 

    This is made up of your brain and spinal cord, this receives and processes signals sent from throughout your body.

    • Peripheral nervous system

    • Autonomic nervous system

    • Voluntary nervous system

    • Central nervous system

    • Circulatory system

    Correct Answer
    A. Central nervous system
    Explanation
    The central nervous system is made up of the brain and spinal cord, and it is responsible for receiving and processing signals sent from throughout the body. It acts as the control center of the body, coordinating and regulating various bodily functions. The peripheral nervous system, autonomic nervous system, voluntary nervous system, and circulatory system are not responsible for receiving and processing signals from throughout the body, making them incorrect answers.

    Rate this question:

  • 3. 

    Different parts of your brain communicate through these nerve cells.

    • Sensory organs

    • Neurons

    • Voluntary nervous system

    • Autonomic nervous system

    • Central nervous system

    Correct Answer
    A. Neurons
    Explanation
    Neurons are the correct answer because they are the specialized nerve cells that transmit information throughout the central nervous system and communicate with different parts of the brain. They play a crucial role in sensory perception, voluntary movement, and the regulation of involuntary processes through the autonomic nervous system. Neurons are responsible for transmitting electrical signals and allowing for the communication and coordination between different areas of the brain and the rest of the body.

    Rate this question:

  • 4. 

    Any change in your environment that is perceived by your senses.

    • Stimulus

    • Neurons

    • Sensory organs

    • Synapse

    • Aorta

    Correct Answer
    A. Stimulus
    Explanation
    A stimulus refers to any change in the environment that is detected by our senses. It can be a physical, chemical, or biological change that triggers a response in our sensory organs. Neurons play a crucial role in transmitting the information from these sensory organs to the brain, where it is processed and interpreted. The synapse is the junction between two neurons where the transmission of signals occurs. The aorta, on the other hand, is the largest artery in the body responsible for carrying oxygenated blood from the heart to the rest of the body.

    Rate this question:

  • 5. 

    This controls body functions, such as your heart beating, that you do not have to think about.

    • Stimulus

    • Central nervous system

    • Sensory organs

    • Neurons

    • Autonomic nervous system

    Correct Answer
    A. Autonomic nervous system
    Explanation
    The autonomic nervous system controls involuntary body functions, such as heart rate, digestion, and breathing. It works automatically, without conscious effort or thought. This system is responsible for regulating and maintaining internal body processes, allowing us to focus on other tasks without having to consciously control these functions. The other options listed, such as the central nervous system, sensory organs, and neurons, are all important components of the nervous system, but they do not specifically control these involuntary functions.

    Rate this question:

  • 6. 

    The collection of sensory and motor nerves in the body.

    • Central nervous system

    • Peripheral nervous system

    • Voluntary nervous system

    • Autonomic nervous system

    • Nerves

    Correct Answer
    A. Peripheral nervous system
    Explanation
    The peripheral nervous system is the correct answer because it is responsible for collecting sensory information from the body's sensory organs and transmitting it to the central nervous system (brain and spinal cord) for processing. It also carries motor commands from the central nervous system to the muscles and glands, allowing for voluntary and involuntary movements. The peripheral nervous system includes all the nerves outside of the brain and spinal cord, connecting the central nervous system to the rest of the body.

    Rate this question:

  • 7. 

    The system that controls skeletal muscles.

    • Circulatory organs

    • Central nervous system

    • Voluntary nervous system

    • Peripheral nervous system

    • Autonomic nervous system

    Correct Answer
    A. Voluntary nervous system
    Explanation
    The voluntary nervous system is responsible for controlling skeletal muscles. Unlike the autonomic nervous system, which controls involuntary actions, the voluntary nervous system allows us to consciously control our movements. This system receives signals from the central nervous system and sends them to the skeletal muscles, allowing us to perform actions such as walking, running, and lifting objects.

    What is the difference between a physical change and a chemical change? Give an example of each.
