Histology and Tissue Types

A set of flashcards covering key vocabulary and concepts related to histology and tissue types from the lecture notes.

Epithelial Tissue

A type of tissue that covers body surfaces and lines cavities, involved in secretion, absorption, and protection.

Connective Tissue

A type of tissue characterized by an extracellular matrix, includes tendons, cartilage, blood, and fat.

Muscle Tissue

Tissue that contracts to produce movement; includes skeletal, cardiac, and smooth muscle.

Nervous Tissue

Tissue responsible for signaling and communication within the body using neurons.

Stratified Epithelium

Epithelial tissue with two or more layers of cells, providing protection.

Simple Epithelium

Epithelial tissue consisting of a single layer of cells, involved in absorption and secretion.

Squamous Cells

Flat, scale-like cells found in simple and stratified epithelium.

Cuboidal Cells

Cube-shaped cells with a central nucleus, commonly found in simple cuboidal epithelium.

Columnar Cells

Tall, column-like cells with nuclei typically located at the bottom, found in simple columnar epithelium.

Pseudostratified Epithelium

A type of epithelium that appears stratified but is actually a single layer, often with cilia.

Transitional Epithelium

A unique type of epithelium that can stretch and is found in the bladder.

Endocrine Glands

Glands that secrete hormones directly into the bloodstream, involved in regulation.

Exocrine Glands

Glands that secrete substances through ducts to external surfaces, such as digestive enzymes.

Basement Membrane

A thin layer of connective tissue that supports and anchors epithelial tissue.

Goblet Cells

Mucus-secreting cells found in simple columnar and pseudostratified epithelia.

Cilia

Microscopic hair-like structures that enable movement and help in absorption or secretion.
