Question

practice: define terms associated with a homeostatic system

which component of a homeostatic system measures the value of a regulated variable?

a. effector
b. integrator
c. sensor
d. set point
e. i do not know the answer.

Explanation:

Identify the question's core concept

Using the Homeostasis knowledge point
The question asks which component of a homeostatic system measures the value of a regulated variable.

Analyze the components of a homeostatic loop

Using the Homeostatic Control Loop knowledge point

• Sensor (or receptor): Detects and measures the actual value of the regulated variable.
• Integrator (or control center): Compares the measured value against the set point.
• Effector: Executes the response to adjust the variable back toward the set point.
• Set point: The target value or range for the regulated variable.

Determine the correct option

The component that measures the value is the sensor. This corresponds to option c.

Answer:

• a. effector
• b. integrator
• c. sensor (Correct answer)
• d. set point
• e. I do not know the answer.
