Study Notes
Simple Squamous Epithelium
- Function: Involved in filtration and diffusion, found in kidneys and lungs; also has a role in secretion within serous membranes.
- Location: Lines cardiovascular and lymphatic systems (endothelium), forms serous membranes (mesothelium), and is present in air sacs of lungs and kidney glomeruli.
Simple Cuboidal Epithelium
- Function: Primarily serves in secretion and absorption.
- Location: Covers ovarian surfaces, lines kidney tubules, and forms parts of glands including thyroid and pancreas.
Nonciliated Simple Columnar Epithelium
- Function: Enhances secretion and absorption; secretes mucus to protect digestive and respiratory linings.
- Location: Lines the gastrointestinal tract from stomach to anus, as well as ducts of various glands.
Ciliated Simple Columnar Epithelium
- Function: Cilia move mucus and particles; aids in moving oocytes through the fallopian tubes.
- Location: Lines bronchioles, fallopian tubes, uterus, and parts of the central nervous system.
Pseudostratified Columnar Epithelium
- Function: Ciliated type traps and eliminates foreign particles; nonciliated type offers absorption and protection.
- Location: Ciliated lines upper respiratory airways; nonciliated lines ducts of glands and male reproductive structures.
Stratified Squamous Epithelium
- Function: Provides protection against physical abrasion, water loss, UV radiation, and pathogen invasion.
- Location: Keratinized type forms skin’s outer layer; non-keratinized type lines moist surfaces (mouth, esophagus, vagina).
Stratified Cuboidal Epithelium
- Function: Primarily offers protection with limited secretion and absorption.
- Location: Found in ducts of sweat glands, esophageal glands, and parts of male urethra.
Stratified Columnar Epithelium
- Function: Provides protection and facilitates secretion.
- Location: Lines part of the urethra, large gland ducts, and certain mucous membranes.
Transitional Epithelium
- Function: Enables stretching of urinary organs while maintaining a protective lining.
- Location: Lines the urinary bladder, ureters, and urethra.
Endocrine Glands
- Function: Secrete hormones to regulate metabolism and physiological activities for homeostasis.
- Location: Varies widely across the body, dependent on the specific glands involved, such as thyroid and adrenal glands.
