Which receptors are classified primarily for sensing touch and pressure on the surface of the skin?

Exteroreceptors are specialized sensory receptors located at or near the surface of the body, making them crucial for detecting external stimuli such as touch, pressure, temperature, and pain. They play a vital role in our ability to interact with our environment by relaying sensory information about what is happening on the skin's surface.

These receptors, such as Meissner's corpuscles and Pacinian corpuscles, are responsive to different types of mechanical stimuli. For instance, Meissner's corpuscles are sensitive to light touch, while Pacinian corpuscles are responsive to deeper pressure and vibration. The classification of these receptors as exteroreceptors highlights their function in sensing the external environment, distinguishing them from other receptor types that respond to stimuli from within the body or in response to changes in the body's internal state.

In contrast, proprioceptors are responsible for sensing the position and movement of the body, interoceptors detect internal body conditions (like hunger or thirst), and baroreceptors specifically respond to changes in blood pressure. Each of these receptors serves distinct functions, reinforcing why exteroreceptors are the correct choice for sensing touch and pressure on the surface of the skin.
