Study Notes
Simple Columnar Epithelium
- Composed of a single layer of cells, providing a smooth surface for various functions.
- Cells are shaped like tall columns, enhancing their role in absorption and secretion.
- Contains one level of nuclei which are located near the base of the cells.
- Consists of tightly packed cells that form a protective barrier.
- Characterized by the presence of cilia, microvilli, and goblet cells, each serving specialized functions.
Location and Specialization
- Found in the stomach, uterine tubes, and small intestine, playing critical roles in these organs.
- Specialized cells include ciliated and non-ciliated forms, enhancing movement and secretion abilities.
Functions
- Functions include protection, secretion, and absorption.
- Cilia facilitate the movement of eggs in the uterine tubes.
- Non-ciliated variant secretes digestive fluids and absorbs nutrients, lining the uterus and portions of intestines.
Surface Area Enhancement
- Microvilli increase the surface area of intestinal cells, aiding in efficient movement, secretion, and absorption of nutrients.
Goblet Cells
- Goblet cells are specialized simple columnar epithelial cells that produce and secrete mucus.
- Their mucus secretion protects mucous membranes and stains purple under a microscope.
Microvilli
- Tiny hair-like structures attached to the cell membrane, increasing the surface area.
- Essential for improving the efficiency of absorption and secretion in epithelial tissues.
