Tissue

Group of cells working together to perform one or more specialized functions

Intracellular

The internal environment of the cells, contained within the cellular membrane

Extracellular

The environment outside the cells, or outside the cellular membrane

Extracellular matrix

Large network of proteins, molecules, and fluid that surrounds and gives structures to cells

Histology

The microscopic study of the structure of tissues and their surrounding extracellular matrix

Epithelial Tissue

Covers exposed surfaces, lines passageways/cavities, and can produce glandular secretions

Connective Tissue

Supports and underlies other structures and fills the internal space of the body, transports materials and stores energy

Muscle Tissue

Contracts to enable movement, moves fluids

Nervous Tissue

Carries electrical impulses and translates information to control activities of the body.
