Homeostasis, Feedback Mechanisms, and Anatomical Position Terms

A set of vocabulary flashcards covering homeostasis, feedback mechanisms, and anatomical positioning terms described in the notes.

Homeostasis

*BALANCE*The body's ability to maintain a stable internal environment despite external changes.

Receptor (sensor)

Detects changes in the internal or external environment.

Control Centre

Processes information and determines the appropriate response (e.g., hypothalamus).

Effector

Organs or tissues (muscles or glands) that carry out corrective actions.

Negative Feedback

A mechanism that reduces or reverses deviations from the set point to restore stability.

Positive Feedback

Mechanism that amplifies or reinforces the initial change rather than reversing it.

Set Point

The target value for a physiological variable that the body aims to maintain.

Homeostatic Imbalance

Failure of regulation that leads to disorder or disease.
