concept: Homeostatic mechanisms use negative feedback to regulate a normal condition. Whether a positive or negative change from the normal condition occurs‚ the body counteracts it to restore the norm. [ Refer to figure 1 in annex below ] Osmoregulation is the process where the body regulates a constant blood water potential by controlling its water and solute concentrations.

Hypothermia causes alterations of the body’s core temperature activating not only physiological but behavioral responses as well in an effort to maintain homeostasis (34). Upon receiving an uninterrupted sensation of cold‚ the skin’s motor neurons are stimulated which creates the shiver response within the muscles of the body. This response is an effort to generate heat which is stated to begin within the trunk
