BIO 1101: Introduction to Tissues

Comprehensive vocabulary flashcards covering the four primary tissue types and the detailed classification, characteristics, and locations of epithelial tissues based on BIO 1101 lecture notes.

Tissue

A tissue is composed of specialized cells of similar structure that perform a common function in the body.

Epithelial Tissue

A primary tissue type focused on covering and lining; also called epithelium.

Connective Tissue

A primary tissue type focused on providing support.

Muscle Tissue

A primary tissue type focused on movement.

Nervous Tissue

A primary tissue type focused on control.

Avascular

A characteristic of epithelial tissue meaning it contains no blood vessels.

Highly regenerative

A characteristic of epithelial tissue describing its high rate of mitosis to replace its cells.

Apical surface

The superficial surface of epithelial cells.

Basal surface

The deep surface of epithelial cells.

Simple

An epithelial classification describing a single layer of cells.

Stratified

An epithelial classification describing more than one layer of cells.

Squamous

An epithelial cell shape described as flat.

Cuboidal

An epithelial cell shape described as block or cube-shaped.

Columnar

An epithelial cell shape described as taller than wide or rectangular.

Transitional

An epithelial cell shape that changes shape and allows for stretching.

Pseudostratified

Meaning "falsely" stratified; a single layer of cells that vary in height.

Simple Squamous Epithelium

A single layer of flat cells found in the alveoli of the lungs, the glomeruli of the kidneys, and the lining of blood vessels.

Simple Cuboidal Epithelium

A single layer of cube shaped cells found in the lining of the kidney tubules.

Simple Columnar Epithelium

A single layer of rectangular cells found in the lining of the gastrointestinal tract and the respiratory tract.

Pseudostratified Columnar Epithelium

A single layer of cells that vary in height, contain cilia for moving substances, and are found in the lining of the upper portion of the respiratory tract.

Cilia

Cell extensions found on pseudostratified columnar epithelium that function to move substances along the cell surface.

Stratified Squamous Epithelium

More than one layer of cells where apical cells are flat; found in the lining of the esophagus and the epidermis of the skin.

Stratified Cuboidal Epithelium

More than one layer of cells where apical cells are cube shaped; found in the ducts of sweat glands.

Stratified Columnar Epithelium

More than one layer of cells where apical cells are rectangular; found in the lining of the male urethra.

Transitional Epithelium

More than one layer of cells that can change shape to look squamous or cuboidal; found in the lining of the urinary bladder.
