Which types of nerve receptors are involved in sensing pressure and touch?

Pacinian corpuscles and Meissner corpuscles are specialized nerve receptors that play critical roles in the sensation of pressure and touch.

Pacinian corpuscles, also known as Vater-Pacini corpuscles, are found deep in the dermis and are particularly sensitive to deep pressure and vibration. They are rapidly adapting receptors, which means they respond quickly to changes in pressure but do not continue to respond to sustained pressure. This makes them essential for sensing dynamic changes in the tactile environment.

Meissner corpuscles, on the other hand, are located closer to the surface of the skin, particularly in areas that are sensitive to light touch, such as the fingertips, palms, and soles of the feet. They are also rapidly adapting and are especially responsive to changes in texture and the initial sensation of touch.

Together, these two types of receptors allow the body to perceive a wide range of tactile sensations, from light texture to deeper pressure. The combination of their locations and their response characteristics makes them well-suited to detecting pressure and touch stimuli, which is critical for interacting with our environment and performing tactile tasks.

The other choices involve different types of receptors that are not primarily responsible for pressure and touch. For example, thermoreceptors are involved
