Goblet cell

A goblet cell is an example of a unicellular exocrine gland. The secretory component consists of individual cells scattered among the non-secreting cells of the covering (cylindrical) epithelium. Without outlets, they release mucin directly onto their surface, which mainly has a protective and lubricating function. It is found, for example, in the epithelial lining of the trachea or some parts of the gastrointestinal tract.
