Connective tissues are characterized by a matrix consisting of fibers and ground substance. Layers in connective tissues are often described based on their density and arrangement:
1. Loose Connective Tissue: Has a loose arrangement of fibers and more ground substance. Found in areas like the lamina propria of mucous membranes. 2. Dense Connective Tissue: Has densely packed fibers with less ground substance. It is further divided into: - Dense Regular: Fibers are parallel, found in tendons and ligaments. - Dense Irregular: Fibers are arranged randomly, found in the dermis of the skin.
