A tissue is a group of cells, in close proximity, organized to perform one or more specific functions.
There are four basic tissue types defined by their morphology and function: epithelial tissue, connective tissue, muscle tissue, and nervous tissue.
Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules.
Connective tissue underlies and supports other tissue types.
Muscle tissue contracts to initiate movement in the body.
Nervous tissue transmits and integrates information through the central and peripheral nervous systems.
