WebIt is composed mainly of loosely arranged collagen fibres. The papillary layer is named for its fingerlike projections — or papillae — that extend upward into the epidermis. The papillae contain capillaries and sensory touch receptors. Figure 10.4.3 This photo is an enlarged image of epidermal ridges on a finger. WebThey have a network of filaments known as the cytoskeleton (literally, “cell skeleton”), which not only supports the plasma membrane and gives the cell an overall shape, but also aids in the correct positioning of organelles, provides tracks for the transport of vesicles, and (in many cell types) allows the cell to move.

WebIn many insects, certain epidermal cells are specialized as exocrine glands. These large, secretory cells produce compounds (e.g. pheromones, repellants, etc.) that are released on the surface of the exoskeleton through microscopic ducts. Tiny hair-like projections or surface sculpturing of the cuticle are known as microtrichae or pile (PILL-EE).
