MAIN FEATURES OF ANIMAL TISSUES
Tissue | Morphological features |
Epithelial | The cells are very close together, with a very small amount of extracellular matrix |
Connective | Cells separated by large amounts of extracellular matrix |
Muscular | Elongated cells with little extracellular material between them |
Nervous | Most cells have extensions that form complex networks with other nervous cells and with cells of other tissues. Very little extracellular matrix |
Tissue | Some main functions |
Epithelial | Coating of the external surface and internal surfaces of the body; secretion |
Connective | Support of the whole body, its tissues and organs, filling of spaces, nourishment of cells of other tissues, bodily defense, secretion |
Muscular | The contraction of its cells generates movement, secretion |
Nervous | Generation, integration and transmission of nervous impulses, secretion |
