Read the disclaimer. General histology. Summary Tissues are formed by cells and can be differentiated into four different types: connective tissue , muscle tissue , nerve tissue , and epithelium epithelial tissue. Overview of the four basic tissue types There are four basic types of tissues in the body: epithelium , connective tissue , nervous tissue, and muscle tissue. Striated muscle Cardiac muscle Skeletal muscle Smooth muscle Epithelium epithelial tissue Surface epithelium Glandular epithelium Epithelium Definition : : The epithelium is one of four basic types of tissues and is present in almost all organs of the human body as lining and glandular tissue.
Classification according to function Surface epithelium Glandular epithelium Distribution : covers all inner and outer surfaces of the body skin and mucous membranes Exception: synovial membrane synovium The synovial membrane is composed of synoviocytes not epithelial cells! Formation : Different types of epithelia are formed from the three germ layers. Ectoderm : epithelium of skin and skin appendages Mesoderm Epithelium of serous membranes mesothelium : peritoneum , pleural, and pericardial cavities Cells lining the inner surface of blood and lymphatic vessels endothelium Endoderm : epithelium of the respiratory and gastrointestinal tract Surface epithelium Definition : A specialized layer of tissue formed by closely aggregated cells that line the outer surface of organs, blood vessels, the skin , and the inner surface of body cavities.
Glandular epithelial cells are shown by rectangular shapes, which line the exterior of the glands. A histological example of adenocarcinoma is shown in Figure 4. Figure 4. Adenocarcinoma of the Lung. Glandular epithelial cells create the lining of the duct, while the cancerous cells shown in the center of the duct are malignant glandular epithelial cells.
