Epithelial Tissues Microscopy Review

Vocabulary flashcards identifying tissue types, key features, functions, and anatomical locations based on the tissue classification histology presentation.

Epithelial Tissues

Tissues that line body surfaces, structures, and organs, acting as a protective barrier and aiding in secretion, absorption, and filtration.

Transitional Epithelium

A stretchy tissue type found in organs that expand, such as the bladder.

Ciliated Simple Columnar Epithelium

A single layer of column-shaped cells attached to the basement membrane, involved in secretion and moving mucus via the mucociliary ladder; located in the fallopian tubes.

Nonciliated Simple Columnar Epithelium

A single layer of columnar cells attached to the basement membrane, specialized for absorption and secretion in the GI tract, stomach, and gallbladder, often featuring microvilli.

Brush Border

A specialized cell surface consisting of microvilli on nonciliated simple columnar epithelial cells that functions in absorption within the GI tract.

Mucociliary Ladder

A mechanism powered by ciliated epithelial cells to secrete and move mucus along passage walls, such as in the fallopian tubes and respiratory tracts.

Pseudostratified Columnar Epithelium

An epithelial tissue layer that typically contains goblet cells and cilia for mucus secretion and transportation of substances, found in the trachea and reproductive tracts.

Simple Cuboidal Epithelial

A single layer of cube-shaped cells surrounding a central lumen, specialized for secretion in glands or absorption in kidney tubules.

Lumen

The internal space or cavity surrounded by cuboidal epithelial cells within tubular structures like kidney tubules and glands.

Stratified Squamous Epithelial

A multi-layered tissue characterized by continuous regeneration and the sloughing off of free cells at the top surface; lines the skin and vagina.

Simple Squamous Epithelial

A tissue consisting of a single layer of flat, thin cells designed for efficient filtration and exchange across surfaces like lung alveoli.
