Question

predict the types of problems that would occur if the nervous system could not maintain homeosta

Answer 1

Homeostasis is a mechanism by which body maintains stable internal balance,The nervous system maintains homeostasis by controlling and regulating the other parts of the body,  A deviation from a normal set point acts as a stimulus to a receptor, which sends nerve impulses to a regulating center in the brain. The brain directs an effector to act in such a way that an adaptive response takes place. for e.g, if the body temperature falls below normal,the adaptive response returns the body to a state of normalcy . When the cells in the body begin to malfunction, the homeostatic balance becomes disrupted. Eventually this leads to disease or cell malfunction. if homeostasis is disrupted than a disease or disorder would occur,Aging is a general example of disease as a result of homeostatic imbalance as an organism ages, weakening of feedback loops gradually results in an unstable internal environment., this lack of homeostasis increases the risk for illness and is responsible for the physical changes associated with aging. another most common disease that occurs due to homeostatic imbalance is diabetese, which is metabolic disorder  where the pancreas is no longer producing adequate amounts of insulin to respond to changes in a person's blood glucose levels as a result blood glucose levels shoot up. Hypertension is another example of homeostatic imbalance, when blood pressure is high, homeostatic mechanism involved is it causes baroreceptor to vasodilate so that blood pressure is restored to normal levels, but if this mechanism is disrupted the body cannot maintain normal blood pressure as a result hypertension results. Heart failure is the result of negative feedback mechanisms that become overwhelmed, this failed mechanism could result in enlargment of heart, which eventually becomes too stiff to pump blood effectively, resulting in heart failure.
