Tactile hairs are associated with a sensory function and are much thicker and stiffer than other hairs.  They are mainly found on the face and can also be referred to as '''''whiskers''''' or '''''vibrissae'''''.  Their follicles are much deeper into the subcutins than guard or wool hairs and possess a venous sinus and nerve endings with mechanoreceptors.  During embryonic development, they appear before other hair types.
