LEPIDIC TISSUES Meaning and
Definition
-
Lepidic tissues refer to a specific type of tissue pattern observed in the human body, particularly in the context of histology and pathology. The term "lepidic" is derived from the Greek word "lepis," meaning "scale," which is aptly chosen to describe the characteristic appearance of these tissues.
Lepidic tissues are characterized by the presence of multiple layers of flattened or cuboidal epithelial cells, closely resembling the overlapping scales of fish or reptiles. This arrangement gives the tissue a distinctive layered or stratified appearance when examined under a microscope. Often, lepidic tissues are found lining the surfaces of organs or covering the inner linings of body cavities.
These tissues play a vital role in providing protective barriers and facilitating various physiological functions. For instance, the lepidic tissues that line the respiratory tract help in filtering and trapping foreign particles, preventing them from entering the lungs. In the urinary system, lepidic tissues line the ureters, bladder, and urethra, aiding in the smooth passage of urine and preventing the leakage of toxic substances into surrounding tissues.
When analyzing pathological specimens, the presence or absence of lepidic tissues can hold diagnostic significance. Alterations or abnormalities in these tissues may indicate certain conditions, such as neoplastic growths or inflammations. Therefore, understanding the structure, function, and variations of lepidic tissues is crucial for medical professionals to make accurate diagnoses and provide appropriate interventions for patients.

Lining-membrane tissues, those "in which the blood-vessels do not penetrate the groups of specific cells, and in which there is an absence of definite stroma between the individual cells, although such stroma, of mesenchymatous origin, may be present between the groups of cells." (Adami.).
