Question

the figure shows a homeostatic system with four components (a, b, c, and
egulated variable\).

which box represents the effector of the homeostatic system?

a. box a
b. box b
c. box c
d. i do not know the answer.

Explanation:

Identify the components of the feedback loop

In Homeostatic Regulation, a standard negative feedback loop consists of three primary functional components:

1. Sensor (or Receptor): Detects changes in the regulated variable and sends input signals to the control center.
2. Control Center (or Integrator): Evaluates the incoming signal against a set point and sends output signals to the effector.
3. Effector: Receives signals from the control center and acts to bring the regulated variable back toward the set point.

Analyze the diagram connections

Let's trace the flow of information in the provided diagram:

• The regulated variable is monitored by Box A. This means Box A acts as the sensor/receptor, detecting the state of the variable.
• Box A sends its signal to Box B. This makes Box B the control center/integrator, which processes the information.
• Box B sends a signal to Box C. This makes Box C the effector, which carries out the response.
• Box C directly influences and alters the regulated variable (indicated by the arrow pointing from Box C back to the regulated variable), completing the feedback loop.

Determine the effector

Based on the signal pathway:

• Box A = Sensor
• Box B = Control Center
• Box C = Effector

Therefore, Box C represents the effector of this Homeostasis system.

Answer:

• a. Box A
• b. Box B
• c. Box C (Correct answer)
• d. I do not know the answer.
