The ridges on the surface of the skin, especially on the fingertips and toes, are caused by the dermal papillae—small, finger-like projections of the dermis (the inner layer of the skin) that push upward into the epidermis. These dermal papillae create unique patterns of friction ridges, which appear as the visible lines and whorls we see on the skin surface.

👉 These ridges are important because:

They improve grip and traction on surfaces.

They enhance sensitivity by increasing the skin’s ability to detect textures.

They form the basis of fingerprints, which are unique to every individual.
