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.
