Study Notes
Simple Epithelium (One Layer of Cells)
- Squamous cells line vessels (endothelium) and serous cavities like the pericardium, pleura, and peritoneum (mesothelium).
- Squamous cells facilitate movement of the viscera (mesothelium), active transport via pinocytosis (mesothelium and endothelium), and secretion of biologically active molecules (mesothelium).
- Cuboidal cells cover the ovary and thyroid.
- Cuboidal cells function in covering and secretion.
- Columnar cells line the intestine and gallbladder.
- Columnar cells function in protection, lubrication, absorption, and secretion.
Stratified Epithelium (Two or More Layers of Cells)
- Squamous keratinized (dry) epithelium is found in the epidermis.
- Squamous keratinized epithelium provides protection and prevents water loss.
- Squamous nonkeratinized (moist) epithelium lines the mouth, esophagus, larynx, vagina, and anal canal.
- Squamous nonkeratinized epithelium provides protection, secretion, and prevents water loss.
- Cuboidal cells are located in sweat glands and developing ovarian follicles.
- Cuboidal cells function in protection and secretion.
- Transitional epithelium is found in the bladder, ureters, and renal calyces.
- Transitional epithelium's main function is protection and distensibility.
- Columnar epithelium is located in the conjunctiva.
- Columnar epithelium provides protection.
Pseudostratified Epithelium (Layers of Cells with Nuclei at Different Levels)
- Not all pseudostratified cells reach the surface, but all adhere to the basal lamina.
- Pseudostratified epithelium lines the trachea, bronchi, and nasal cavity.
- Pseudostratified epithelium functions in protection, secretion, and cilia-mediated transport of particles trapped in mucus out of the air passages.
