A hair-like or thread-like structure found on the surface of an organism, or in anatomy, a layer of tissue involving hair follicles or similar structures.
From Greek 'epi-' (upon) and 'trichium,' a diminutive of 'thrix' (hair). The Latinized form appeared in anatomical and biological texts to describe surface hair structures.
Your skin has about 100,000 hair follicles, and each one is a tiny engineering marvel with its own oil gland and blood supply—the epitrichium would be the outermost layer of cells connected to these structures.
