What is another name for a pore?

The term "ostium" or "ostia" refers specifically to the opening of a pore, especially in relation to the skin. In the context of esthetics, pores are small openings on the skin's surface that allow for the secretion of sweat and oil, contributing to the skin's health and function. The use of "ostium" highlights the anatomical nature of the pore, as it denotes the entrance to a structure, such as a hair follicle or sweat gland.

Understanding the terminology is crucial for estheticians, as it helps in accurately communicating about skin conditions, treatments, and anatomy. This distinction can be particularly useful when discussing various treatments or products aimed at improving the appearance and health of the skin. The other options do not accurately describe pores: "fistula" is a type of abnormal connection between bodily structures, "follicle" refers to the structure that produces hair, and "tube" is a general term that lacks the specificity associated with skin pores.
