we sense these organisms will be the cell present on our epidermis named nervecell or neurons

Our skin acts as the protective barrier between our internal body systems and the outside world. It’s not only the body’s largest sensory organ, but it’s also the largest organ–period!
The skins “sense of touch” is what gives our brains a wealth of information about the natural environment, including temperature, humidity, and air pressure.
Most importantly, this sense of touch lets us feel physical pain–a necessity for avoiding injury, disease, and danger.
It is truly amazing how much information we receive about the world through our sense of touch, and although we still don’t know all the ins and outs of how the skin perceives touch, what we do know is interesting
Mechanoreceptors: These receptors perceive sensations such as pressure, vibrations, and texture. There are four known types of mechanoreceptors whose only function is to perceive indentions and vibrations of the skin: Merkel’s disks, Meissner’s corpuscles, Ruffini’s corpuscles, and Pacinian corpuscles. The most sensitive mechanoreceptors, Merkel’s disks and Meissner’s corpuscles, are found in the very top layers of the dermis and epidermis and are generally found in non-hairy skin such as the palms, lips, tongue, soles of feet, fingertips, eyelids, and the face.
Thermoreceptors: As their name suggests, these receptors perceive sensations related to the temperature of objects the skin feels. They are found in the dermis layer of the skin. There are two basic categories of thermoreceptors: hot and cold receptors.
Pain receptors: The scientific term is nocireceptor. “Noci-” in Latin means “injurious” or “hurt” which is a good clue that these receptors detect pain or stimuli that can or does cause damage to the skin and other tissues of the body. There are over three million pain receptors throughout the body, found in skin, muscles, bones, blood vessels, and some organs.
Proprioceptors: In Latin, the word “proprius” means “one’s own” and is used in the name of these receptors because they sense the position of the different parts of the body in relation to each other and the surrounding environment. Proprioceptors are found in tendons, muscles, and joint capsules. This location in the body allows these special cells to detect changes in muscle length and muscle tension. Without proprioceptors, we would not be able to do fundamental things such as feeding or clothing ourselves.
