Excoriation : Straight scratches that result in the loss of the top layer of skin. Fissure: Straight breaks in the skin that go deeper than the top layer of skin into the second layer of skin. They can be painful and can be caused by excessive dryness. Lichenification : A rough thickening of the top layer of skin.Weight loss. Another common cause of a dent in shin without pain is a result of weight loss. When you lose weight, your body undergoes a significant change in its composition, which can lead to changes in the distribution of fat and muscle tissue. This can result in an indentation in the skin, particularly on the shins.While hairy skin Aβ RA-LTMRs and Aδ-LTMRs are rapidly adapting to static indentation of the skin and the C-LTMRs intermediately to slowly adapting, all three lanceolate ending types are highly sensitive to hair deflections and skin stroke (Figure 2C) 1,7,32,136. It is reasonable to assume, therefore, that the lanceolate ending structure ...The average value of the skin Young’s modulus, found by Pailler-Mattei et al [11], between 4.5 kPa and 8 kPa for indentation tests.

Caused by tight elastic or tied string.Local skin indentation in the 5–20 Hz range generates cues that allowed participants to make discrimination based on the overall spatial pattern of stimulation, i.e. shape. In contrast, in the 40–80 Hz range, shape cannot be discerned, but skin stretch and the rate of its variation continue to inform the percept of roughness. ...Skin dimpling overlying a tumor/cancer growing in the breast can be a presentation of breast cancer, especially if the lump is growing closer to the overlying skin. 2. Why does this happen? When a cancer grows within the breast, it distorts the normal architecture of the breast tissue, which can then distort the look of the overlying breast ...Skin cancer has a plethora of presentations.

May 21, 2021 · Rolling scars are pits or indentations in the skin, and they often have sloped sides. Each of these pits may be wider than 4–5 millimeters. They give the skin an uneven appearance and can be difficult to conceal. People with rolling scars may also have other types of acne scars, including discolored or raised marks. Kelsey5241. I recently noticed a discolored indented spot on my upper arm.. It is about 1 1/2 inch long and 1/2 inch wide. Very irregular shape similar to a birthmark.
