Which of the following detect mechanical energy associated with changes in pressure, position, or acceleration?

Options

A. Chemoreceptors
B. Photoreceptors
C. Mechanoreceptors
D. Thermoreceptors

Explanation

To solve the question "Which of the following detect mechanical energy associated with changes in pressure, position, or acceleration?", we can analyze the options provided:

1. **Chemoreceptors**: These receptors are specialized to detect chemical stimuli. They respond to changes in chemical concentrations, such as gases or other chemical substances. Therefore, they do not detect mechanical energy.

2. **Photoreceptors**: These receptors are sensitive to light. They detect light energy and are primarily involved in vision. Thus, they do not respond to mechanical changes.

3. **Mechanoreceptors**: The prefix "mechano-" refers to mechanical energy. Mechanoreceptors are specifically designed to detect mechanical changes such as pressure, position, or acceleration. This makes them the correct choice for the question.

4. **Thermoreceptors**: These receptors are sensitive to temperature changes. The prefix "thermo-" indicates that they respond to thermal energy rather than mechanical energy.

After analyzing all the options, we can conclude that the correct answer is:

**C. Mechanoreceptors**
