Indentation in skin.
The mechanical state encoded by slowly adapting type 1 mechanoreceptors (SAI) during indentation was examined using an isolated preparation in a rat model. Skin and its intact innervation were harvested from the medial thigh of the rat hindlimb and placed in a dish, with the corium side down, containing synthetic interstitial fluid.
MeSH terms. Psychophysical tests on human subjects showed that judgments of skin indentation depth made when the fingertip was indented at rates from 0.2 to 16 mm/sec were quite insensitive to changes in indentation velocity. Similar results were obtained on the forearm at indentation velocities of 0.4 to 16 mm ….It is an inflammation of the fat under the skin, which shrinks (atrophies) and causes visible dents. It is one of the skin conditions of lupus. The broken-looking blood vessels may be telangiectasias, dilated small vessels in the skin, also common in lupus. Both conditions frequently occur on the face.Given the foregoing, it would be most prudent to employ subcision--which is an entirely natural technique for breaking up tethering bands of scar collagen that pulls skin down and promotes new native collagen and elastic fiber synthesis in order to elevate and smooth the dimple. Make sure to consult with an experienced, board certified cosmetic ...Answer: Depression in the forehead. The depression next to the vein shown is commonly seen. The treatment is volumization.
