Document Summary
Areolar connective tissue: nuclei, collagen fibers, elastic fibers, ground substance. Adipose tissue: nuclei, adipocytes (adipose cell, cell membrane. Skeletal muscle: nuclei, individual muscle cells, striations. Cardiac muscle: nuclei, individual muscle cells, intercalated discs, striations. Smooth muscle: nuclei, individual muscle cells. Diverse, abundant, widely distributed throughout the body. Functions: structural support, binding structures together, back storage, exchange of nutrients and metabolic waste, defense/protection. Cells, protein fibers, ground substance: last 2 are extracellular matrix. Abundant ground substance and scattered cells and loosely arranged protein fibers. Areolar: subcutaneous layer and around organs, gel ground substance, numerous blood vessels, scattered fibroblasts. Adipose: in subcutaneous tissue and around some organs, close packed adipocytes. Reticular: stroma (connective tissue in lymph nodes, spleen, thymus, and bone marrow, reticular fibers. Scattered fibroblasts and leukocytes (wbcs) in gel like ground substance. Abundant tightly packed fibers, relatively few cells and ground substance. Dense regular: tendons and ligaments, dense parallel college fibers and fibroblasts between layers with little ground substance.
