Homeostasis Lecture Notes

Flashcards covering key terms and definitions related to homeostasis from the lecture notes.

Homeostasis

The maintenance of the internal environment of the body.

Set point

The ideal norm value for a homeostatic variable.

Normal Range

Values that increase or decrease around a set point.

Variables

Factors that can change homeostatic levels.

Negative Feedback

The mechanism to maintain homeostasis by resisting any deviation from the Set Point.

Receptor

Monitors the value of the variable.

Control Centre

Receives information about the variable.

Effector

Produces responses that change the value of the variable.

Positive Feedback

When a deviation from the norm occurs it gets larger; not a normal homeostatic response.

Thermoregulation

The homeostatic regulation of body temperature.

Osmoregulation

The homeostatic regulation of body water levels.

Glucoregulation

The homeostatic regulation of blood sugar levels.

Homeostatic Imbalance

A condition where homeostasis is not maintained, leading to diseases.

Diabetes

An inability to regulate blood sugars.

Dehydration

An imbalance in body water levels.

Hypoglycemia

Low blood sugar.

Hyperglycemia

High blood sugar.

Gout

A disease characterized by high uric acid levels.
