Study Notes
Types of Epithelial Tissues
- Two main types of epithelial tissues: glandular and non-glandular epithelium
Glandular Epithelium
- Endocrine glands: release secretions (hormones) directly into the blood
- Exocrine glands: release secretions into a duct that leads to the surface of an epithelium or an organ
Exocrine Glands
- Primary function: secrete enzymes and other substances onto a surface or into a body cavity
- Classified based on structure:
- Unicellular glands: consist of single cells, such as goblet cells
- Multicellular glands: consist of multiple cells, with different structures
Multicellular Glands
- Simple glands: have a rounded secretory part attached to a single unbranched duct
- Compound glands: have secretory portions that are both tubular and rounded, attaching to a branched duct
- Coiled tubular glands: have a tubular secretory portion that is coiled and attaches to a single unbranched duct
- Branching glands: have a secretory part that is branched and attaches to a single unbranched duct
Functional Classification
- Holocrine glands: release secretions by shedding the entire cell
- Merocrine glands: release secretions through exocytosis
- Apocrine glands: release secretions by budding off the apical portion of the cell
Cellular Components
- ER (Endoplasmic Reticulum) and Golgi apparatus: responsible for protein synthesis, modification, and secretion in glandular epithelium
