Stimulus And Response To Homeostasis

Sometimes a fever is the body s response to the bacteria.

Stimulus and response to homeostasis. Response to stimulus causes an action or response due to a change in environment. A positive feedback loop results in a change in the body s status rather than a return to homeostasis. A receptor which is a structure in an organism either in a cell a cell itself or a collection of cells that can detect the stimulus which sends a message either electrical or chemical to.

Body as a thermostat first response to a hot or cold condition. Examples of internal conditions maintained homeostatically are the level of blood glucose body temperature blood calcium level. This is a process in which a neutral stimulus becomes connected to a stimulus that already elicits a response.

The stimulus response model can be shown as a circular diagram like this. The cervix contains stretch sensitive nerve cells that monitor the degree of stretching the sensors. The stimulus activated sensory detectors which then sent the message to the hypothalamus gland where the information was processed and analyzed.

Positive feedback is a mechanism in which an output is enhanced in order to maintain homeostasis. The central nervous system cns the endocrine system. Positive feedback mechanisms are designed to push levels out of normal ranges.

Homeostasis refers to the relatively stable state inside the body of an animal. What is the reason for developing a fever. The first contractions of labor the stimulus push the baby toward the cervix the lowest part of the uterus.

Positive feedback mechanisms are designed to accelerate or enhance the output created by a stimulus that has already been activated. Homeostasis is a state of balance within the body. Once this connection is made the previously neutral stimulus elicits a response.
