A group of closely associated cells that perform related functions and are similar in structure.

Tissue that covers body surfaces, lines cavities, and forms glands.

Protection, movement (absorption, secretion, filtration), forming slippery surfaces.

Densely packed cells, specialized contacts, polar, avascular but innervated, high regeneration rate.

Projections on epithelial cells that increase surface area for absorption and secretion.

Hair-like structures that aid in movement of mucus and substances across the surface.

Simple (1 layer), Stratified (multiple layers), Pseudostratified (appears multiple but is 1).

Squamous (plate-like), Cuboidal (cube-shaped), Columnar (column-like).

A type of epithelium with cuboidal cells at the base and squamous cells at the surface, named for the surface layer.

A single layer of flat cells that facilitates diffusion and filtration, found in areas like the respiratory tract.

A single layer of cube-shaped cells that house organelles for absorption/secretion, found in kidney tubules.

A single layer of column-like cells with varying heights, often ciliated, involved in secretion, especially mucus.

A multi-layered epithelium primarily for protection, often found in sweat glands and mammary glands.

A specialized type of epithelium that allows for stretching, found in the bladder.

Glands that secrete hormones directly into the bloodstream.

Cell junctions that act as barriers, preventing passage of substances between cells.

Passageways between cells allowing ion sharing for electrical impulses.

Most diverse and abundant tissue with cells separated by ECM.

The embryonic layer that forms connective tissue.

Cell that produces fibers in the extracellular matrix (ECM).

Mature cell found in cartilage that maintains its matrix.

Includes loose (areolar, adipose) and dense (regular, irregular, elastic) tissues.

Strong fibers that resist tension better than steel.

Includes hyaline, fibrocartilage, and elastic cartilage.
