Where we can find the glabrous skin?

Glabrous skin Hair-free skin is found mainly on the palms and soles. It is innervated by specialized nerves that help us to understand subtle tactile details. Such skin is thicker than hairy skin; the epidermis is about 1.5 millimetres thick and the dermis is about 3 millimetres deep.

Is Glabrous skin more sensitive?

The skin of the face has been found to be more sensitive to light touch than the glabrous palm skin (Weinstein, 1968; Ackerley et al., 2014), which may relate to the density and type of mechanoreceptive afferents present, as well as the decreased skin thickness.

What is the Glabrous?

Medical Definition of glabrous : having or being a smooth even surface specifically : having or being an epidermal covering that is totally or relatively devoid of hairs or down glabrous skin.

Where are Merkel discs found?

Merkel’s disks are found in the upper layers of skin near the base of the epidermis, both in skin that has hair and on glabrous skin; that is, the hairless skin found on the palms and fingers, the soles of the feet, and the lips of humans and other primates.

Where is glabrous skin found on the body?

The only true glabrous skin is found on the palms of the hands, inner sides of the fingers, soles of the feet, lips, nipples and parts of the genitals. Glabrous skin contains four different sensors that respond to mechanical pressure for fine manipulation of objects.

Is the human body both hairy and glabrous?

The body contains both hairy and non-hairy (glabrous) skin. Even skin which would often be thought of as smooth and non-hairy often contains tiny hairs. The only true glabrous skin is found on the palms of the hands, inner sides of the fingers, soles of the feet, lips, nipples and parts of the genitals.

What’s the difference between hirsute and glabrous skin?

The thick, hairless skin in the palms and soles are therefore called glabrous skin, while skin elsewhere is referred to as hirsute (hairy) skin. Of note, the stratum lucidum is absent from hirsute skin but present in glabrous skin. The epidermis is made up a variety of cell types.

What kind of receptors are found in glabrous skin?

As in the glabrous skin, the hairy skin has SA-I, SAII, RA-I, and RA-II afferents. However, some modifications in the receptor mechanisms exist.
