Which type of sensory receptor detects pressure changes in an organ?

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

Answer: (B)

Verified step by step guidance

1. Begin by understanding the function of sensory receptors. Sensory receptors are specialized cells that detect changes in the environment and send signals to the nervous system.
2. Identify the types of sensory receptors listed in the problem: photoreceptors, mechanoreceptors, thermoreceptors, and chemoreceptors.
3. Photoreceptors are responsible for detecting light and are primarily found in the eyes. They are not involved in detecting pressure changes.
4. Thermoreceptors detect changes in temperature, helping the body respond to heat and cold. They do not detect pressure changes.
5. Chemoreceptors respond to chemical stimuli, such as changes in the concentration of substances. They are not involved in detecting pressure changes. Mechanoreceptors, however, are specialized to detect mechanical changes such as pressure, touch, and vibration, making them the correct type of receptor for detecting pressure changes in an organ.
