The metaplastic epithelium, also called the migratory epithelium, is characterized by its ability to contract and diastole.
Migratory epithelium is also called migratory epithelium because its cellular pattern and layers change as the organ in which it is located contracts or diastasizes. The metaplastic epithelium is a complex epithelium with columnar cells in the superficial layer, spindle-shaped cells in the middle layer, and cone-shaped cells at the basal level, and it is found mainly in the renal pelvis, ureter, bladder, and urethra.
Its form, which is cuboidal, has a relatively large surface cell volume. When the organ is in a contracted state, the epithelium thickens the surface cells in a cubic or oval shape with a larger volume. For example, in the case of a full bladder, the epithelium thins when the organ is distended and the cell morphology changes, such as when the bladder is full.
Consultation with a medical professional is recommended.
