Touch receptors are more abundant than temperature receptors, and cold receptors are more abundant than heat receptors. Ruffini receptors are the ones that detect temperature. ... The size of the areas on the cortex corresponds to the density of receptors for each pathway

Explanation:

The sense of touch is that which allows living organisms to perceive qualities of objects and media such as pressure, temperature, texture and hardness. In the skin there are different kinds of nerve receptors that are responsible for transforming the different types of external stimuli into information that can be interpreted by the brain. The skin is divided into three layers: epidermis, which is the superficial layer, the dermis and the hypodermis which is the deepest layer. The epidermis is constituted by epithelial tissue and in its basal or germinative stratum we find the so-called melanin, which is the pigment that gives color to the skin, and the dermis by connective tissue. In this layer we find the skin annexes that are the sebaceous glands, sweat glands, hair and nails and the hypodermis formed by adipose connective tissue. We must bear in mind that although mainly the sense of touch is in the skin, we also find it in the internal nerve endings of the organism, being able to perceive high temperature changes or pain. So it is the most important of the five senses allowing us to perceive the risks to our health both internally and externally. The part that governs touch in the brain is the parietal lobe.

«When we describe ourselves as sentient beings, what we mean is that we are aware. The most literal and broad meaning is that we have sensory perception. »The tactile folds are used to detect heat, cold, pain or any other sensation; and sensation is one of the functions that consciousness uses to orient itself in outer space, in its environment, as in inner space.
