Why is some parts of the skin more sensitive than others?
The receptors in our skin are not distributed in a uniform way around our bodies. Some places, such as our fingers and lips, have more touch receptors than other parts of our body, such as our backs. That is one reason why we are more sensitive to touch on our fingers and face than on our backs.
What part of skin is the most sensitive?
The face has demonstrated to be the most common site of skin sensitivity (Table 3), predictable physiologically due to the larger and multiple number of products used on the face (particularly in women), a thinner barrier in facial skin, and a greater density of nerve endings (18).
What are the 3 skin senses?
The skin contains receptors that respond to touch, pressure, and temperature. The relationships between receptors and the cutaneous sensations are not completely understood.
Which part of the body is least sensitive?
The least sensitive skin on the human body is found in the heel area. This is because there are very little nerves in the heel to feel things. If there were too many nerves in our heels then walking would be far too painful. The second least sensitive is the elbow.
What is sensitive skin?
Sensitive skin is a lay term rather than a medical diagnosis. It is generally used to describe skin with reduced tolerance to the application of cosmetics and personal care products. In surveys, approximately 50% of women and 40% of men may report having sensitive skin.
Where is the skin least sensitive?
What are receptors in the skin sensitive to?
Your skin receptors don’t only respond to touch. They also register pain as well as warmth and cold. Your pain receptors are the most numerous. Every square centimetre of your skin contains around 200 pain receptors but only 15 receptors for pressure, 6 for cold and 1 for warmth.
What are skin senses?
Definitions of skin senses. the faculty by which external objects or forces are perceived through contact with the body (especially the hands) synonyms: cutaneous senses, sense of touch, touch, touch modality.

Where are the most sensitive skin receptors located?
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.
What are the three main types of skin?
Skin can be divided into three main categories: glabrous skin (e.g., the thicker, non-hairy skin on the palms), hairy skin (e.g., the vast majority of the skin on the body, which contains different types of hairs), and mucocutaneous skin (e.g., the lips).
Why does the skin have so many touch receptors?
When you are in the sun, the melanin builds up to increase its protective properties, which also causes the skin to darken. The epidermis also contains very sensitive cells called touch receptors that give the brain a variety of information about the environment the body is in. The second layer of skin is the dermis.
