- Define negative feedback inhibitionIn describing a positive feedback loop, which of the following would be true? a) the sensor and control center are always the same b) the effector signals the control center to shut off the initial stimulus c) the effect shuts off the initial stimulus d) the effect amplifies the initial stimuGive an example of a feedback mechanism in the human body. Explain your example briefly. Make sure to identify the type of feedback (negative or positive), the receptor, the control center and the effector.
- Organismal homeostasis depends upon the presence of control systems. Give a physiological example of a negative feedback control system its positive feedback. Clearly describe the role(s) that each of the following elements plays in all control systems: such as controller, effector and receptor.Describe how blood sugar (e.g. glucose plasma concentration) is regulated with the hormones, insulin, and glucagon. For this feedback loop, identify the following components of the feedback loop: stimulus, receptor, control center, efferent pathway, effector, and response. Be comfortable with this feedback loop to be able to describe the effects of changing various components of the feedback loop.Define homeostasis. What happens when homeostasis fails? List the three basic components of a control system and give an example. Describe the components of a reflex pathway. Contrast the response loop and the feedback loop. Explain the relationship between a regulated physiological variable and its setpoint. Is the physiological variable exactly at its setpoint? Compare and contrast negative and positive feedback. Give a biological example of each. Is the setpoint constant or can it change over time? If setpoints can change over time, what is this called? Chapter 2:
- Please help to understand the mechanismsWhich of the following is comparable to a positive feedback cycle? a) opening of voltage-gated Ca2+ channels in response to an action potential arriving at the axon terminal b) opening of voltage-gated Na+ channels in response to a depolarizing graded potential c) movement of K+ through leak channels d) operation of the Na+-K+ ATPase at rest e) opening of voltage-gated K+ channels in response to a depolarizing graded potentialIn a negative feedback loop, the effector moves the system in the direction as the stimulus.
