    "During labor, the brain triggers the release of oxytocin to continually stimulate contraction of the uterus until the baby is born" This is an example of:

    • A negative feedback mechanism

    • A positive feedback mechanism

    • There is not enough information

    Correct Answer
    A. A positive feedback mechanism
    Explanation
    This statement describes a positive feedback mechanism. Positive feedback occurs when the output of a system amplifies or reinforces the initial stimulus, leading to a greater response. In this case, the brain triggers the release of oxytocin, which stimulates contractions of the uterus. As the contractions continue, more oxytocin is released, leading to stronger and more frequent contractions until the baby is born. This process demonstrates positive feedback because the initial stimulus (contractions) is amplified and reinforced by the release of oxytocin.

    Muscle is said to be ____________ to the skin.

    • Superficial

    • Lateral

    • Proximal

    • Deep

    • Medial

    Correct Answer
    A. Deep
    Explanation
    Muscle is said to be deep to the skin because it is located underneath the layers of skin. The term "deep" refers to something being situated further inside or away from the surface. In the context of the human body, deep structures are typically located closer to the core or internal organs, while superficial structures are closer to the surface. Therefore, in relation to the skin, muscles are considered deep.

    The body is great at maintaining homeostasis through tempurature regulation.  Which mechanism does temperature regulation follow?

    • A negative feedback mechanism

    • A positive feedback mechanism

    • There is not enough information

    Correct Answer
    A. A negative feedback mechanism
    Explanation
    Temperature regulation follows a negative feedback mechanism. This means that when the body's temperature deviates from the set point, the body initiates processes to bring it back to the normal range. For example, if the body becomes too hot, the negative feedback mechanism will cause sweating to cool down the body. If the body becomes too cold, the negative feedback mechanism will cause shivering to generate heat and warm up the body. This continuous cycle of detecting and correcting temperature imbalances helps maintain homeostasis.

    Example of a mechanism:
    • Glucose from ingested food is absorbed in the intestinal wall and the level of glucose in blood rises.
    • Elevation of glucose concentration in the blood then stimulates the pancreas to release insulin.
    • As a result, blood glucose levels fall.
    In this example, what is the initial stimulus?

    • Glucose levels in blood fall

    • Glucose levels in blood rise

    • Pancreas releases insulin

    • Stimulation of the pancreas

    • Not enough information

    Correct Answer
    A. Glucose levels in blood rise
    Explanation
    The initial stimulus in this mechanism is the rise in glucose levels in the blood. This increase in glucose concentration triggers a response in the pancreas to release insulin, which ultimately leads to a decrease in blood glucose levels.

    Which correctly displays the pathway of communication with a negative feedback mechanism?

    • Stimulus -> effector -> receptor -> control center

    • Stimulus -> receptor -> control center -> effector

    • Stimulus -> receptor -> effector -> control center

    • Stimulus -> control center -> receptor -> effector

    • None of the above

    Correct Answer
    A. Stimulus -> receptor -> control center -> effector
    Explanation
    The correct answer is stimulus -> receptor -> control center -> effector. In a negative feedback mechanism, the pathway of communication starts with a stimulus, which is detected by a receptor. The receptor then sends signals to the control center, which processes the information and initiates a response. Finally, the control center sends signals to the effector, which carries out the response to counteract the original stimulus. This sequence of stimulus, receptor, control center, and effector represents the correct pathway of communication in a negative feedback mechanism.

    In this example of a positive feedback mechanism, what is considered the effector? - ProProfs

    In this example of a positive feedback mechanism, what is considered the effector?

    • Break in the blood vessels

    • Blood clots completed

    • Acceleration of clotting

    • The damaged cells

    • Bleeding

    Correct Answer
    A. The damaged cells
    Explanation
    In a positive feedback mechanism, the effector is the component that amplifies or enhances the initial stimulus. In this example, the damaged cells act as the effector because they trigger an acceleration of clotting, which in turn leads to the formation of blood clots. The blood clots are the amplified response to the initial stimulus of the break in the blood vessels, creating a positive feedback loop.
