Mechanoreceptors respond to which type of stimuli?

Mechanoreceptors respond to which type of stimuli?

• A. Mechanical stimuli
• B. Thermal energy
• C. Chemical substances
• D. Light

Answer: (A)

Mechanoreceptors are specialized to detect physical forces and translate them into neural signals. They respond to mechanical energy such as pressure, touch, stretch, and vibration. This makes mechanical stimuli the correct type of input they sense. When mechanical forces deform these receptors, ion channels open and a receptor potential is produced, which can lead to nerve impulses informing the brain about the physical state of the body or environment. By contrast, thermoreceptors detect thermal energy (heat or cold), chemoreceptors respond to chemical substances, and photoreceptors respond to light.
