ANH573 - 2. Connective Tissues 4 General Characteristics of Connective Tissue Most abundant & widely distributed tissue usually not present on free surfaces has a nerve supply hugely vascular (except in cartilage) various forms & functions Consists of Cells & Matrix in general, connective tissue cells are widely spaced within matrix – a non-cellular material varies in consistency from solid to semifluid to fluid may have fibres of 3 possible types
