Negative+Feedback+Loop+(Hypothalamus+and+Thyroid+Gland)

The negative feedback system is the system that manages healthy conditions in our body. Receptors (sensors) and effectors make sure these conditions remain contant with no change.

With the image above, the change is sent to the sensory, then to the intergrating center stimulating the effector and then the change will be altered.

Hormone/Gland:

(1)Hypothalamus (homeostasis): Both peptide and protein hormones such as antiduretic or prolactin are released which regulate the homeostasis levels in the blood (i.e. temperature of the body). Refering back the the negative feedback loop, these hormones will be sent to the sensors/receptors then to the integrating center stimulating the effector and then changes will be made to either increase or decrease the body temperature. This stops when the correct temperature is present.

(2)Thyroid Gland (calcium): Amine hormones such as throxine and triiodothyronine are released which regulate the calcium levels in the blood. Refering back the the negative feedback loop, these hormones will be sent to the sensors/receptors then to the integrating center stimulating the effector and then changes will be made to either increase or decrease the calcium levels. This stops when the correct amount of calcium is present.
