Answer #1

Answer

In negative feeedback the response reverses a change in a controlled condition. Most processes in the body are controlled by this mechanism.

  • Negative feedback mechanism tends to reduce or inhibit the original stimulus.
  • Negative feedback mechanism is very important in maintaining homeostasis.
  • Example :
    - Increased glucose levels trigger insulin release. Insulin functions to lower blood glucose levels.
    - Increased body temperature triggers sweating. Sweating tends to cool the body surface through evaporation.

One of the disadvantage of negative feedback loop is lag caused because it can only be exerted after controlled variable has been disturbed. In order to minimize lag between a change in a controlled variable and the action of the effector, it is advantageous for the body to anticipate any likely change. Which one of the following physiological mechanism achieves this? Select one: a. Feedbackward control b. Feedforward control c. Positive feedback control d. All of the above e. None...

Blood glucose levels are homeostatically controlled by the brain. When the body detects elevated blood glucose, our brain sends messages to the pancreas resulting in the release of insulin, which causes glucose uptake by cells, thereby decreasing blood glucose. In this example, elevated blood glucose is: the sensor negative feedback the stimulus the response the set poin

You are assessing a patient who presented with intersex genitalia. You find that this individual is genetically male (has one X chromosome and one Y chromosome) and possesses the testis-determining factor (called the SRY gene). Further, they are producing adequate levels of gonadotropin-releasing hormone, follicle-stimulating hormone, and testosterone. What is the most likely explanation for this individual’s intersex genitalia? A.absent or inactive testosterone receptors B.hyposecretion at the level of the hypothalamus C. hyposecretion at the level of the testes D....
