Tissue collection of cells performing similar functions. More than 200 distinguishable kinds of cells in the body. Four classifications of cells: neurons, muscle cells, epithelial cells, connective tissue cells. Neurons specialized to transmit information in the form of electrical signals: receive and transmit information from the environment, relay signals to muscles, glands, and organs, process information. Muscle cells specialized to contract, generating mechanical force and movement. Epithelial cells found in epithelia tissues, which consists of a continuous, sheet- like layer of cells in combination with a thin underlying layer of non-cellular material called a basement membrane: types of epithelia:
