Homeostasis

Question 1

Define homeostasis.

Answer 1

A condition of equilibrium (stability or balance) in the body’s internal environment.

Question 2

What is the stimulus of the feedback system?

Answer 2

Any disruption to a controlled condition

Question 3

What is the receptor/sensor of the feedback system?

Answer 3

Monitors the environment and responds to a stimulus

Question 4

What is the control centre of the feedback system?

Answer 4

Determines set-point / range to be maintained. Analyses input and determines appropriate response (output|)

Question 5

What is the effector of the feedback system?

Answer 5

The muscles or glands which bring about a response or effect.

Question 6

Which are more common negative or positive feedback systems?

Answer 6

Negative

Question 7

What do negative feed back systems do?

Answer 7

They inhibit a negative change and prevent sudden severe changes within the body. Once equilibrium is achieved the process is shut off.

Question 8

What do positive feedback systems do?

Answer 8

They enhance and amplify the effector so that the response will occur at a faster rate and only stop when the stimulus is removed not to do with equilibrium.
