Presentation transcript:

Glandular Epithelium Composed of cells that are specialized to produce and secrete substances into ducts or into body fluids. Such cells are usually found within columnar or cuboidal epithelium & one or more cells make up a gland.

1. Endocrine secretions produced by ductless glands into blood or other fluids. Hormones

2. Exocrine secretions discharged through duct onto internal/external surface. Unicellular -called mucus or goblet cell Multicellular -sweat glands, salivary glands, etc.

Structural Types of Exocrine Glands Simple: communicates with surface with an un-branched duct Compound: branched duct

Types of Exocrine Secretions Merocrine glands fluid product salivary glands pancreas sweat glands Apocrine glands cellular product portions of cells mammary glands ceruminous glands(ear) Holocrine glands secretory products whole cells sebaceous glands
