Introduction to Homeostasis

Homeostatic equilibrium is maintained through negative feedback loops, which involve a stimulus, a control center, and an effector, and positive feedback loops, which amplify a signal and can lead to a runaway effect…

Homeostatic equilibrium is maintained through negative feedback loops, which involve a stimulus, a control center, and an effector, and positive feedback loops, which amplify a signal and can lead to a runaway effect… One important component of homeostasis is the regulation of osmolality, which refers to the balance of solutes and water in the body.

The body’s ability to maintain homeostasis is essential for proper functioning of cells and tissues

effector — an organ or tissue that receives information from the control center and acts to bring about the changes needed for homeostasis. negative feedback — a homeostatic process that counteracts a change, bringing the parameter back toward its set point. feedback loop — a part of homeostasis that provides a mechanism for the body to maintain stability. osmolality — the number of solute particles per kilogram of solvent.

Worked example

What does “effector” mean in Introduction to Homeostasis?

  1. 1Use the wording this chapter gives for effector.
  2. 2The book says: an organ or tissue that receives information from the control center and acts to bring about the changes needed for homeostasis.
  3. 3Do not use the meaning of negative feedback. That term means a homeostatic process that counteracts a change, bringing the parameter back toward its set point.

Result: an organ or tissue that receives information from the control center and acts to bring about the changes needed for homeostasis

Why. That is the meaning this chapter gives for effector.

Do not swap effector and negative feedback. effector means an organ or tissue that receives information from the control center and acts to bring about the changes needed for homeostasis. negative feedback means a homeostatic process that counteracts a change, bringing the parameter back toward its set point.
