Vevsmråder
Vevsmråder, meaning tissue areas, is a term used in histology and anatomy to describe spatially distinct regions within a tissue that differ in cellular composition, extracellular matrix, vascularization, metabolic activity, or gene expression. The concept reflects how tissues are organized into functional units that contribute to overall organ performance.
These regions may arise during development through patterning and differentiation or through ongoing adaptation to mechanical
Studying vevsmråder relies on histology and imaging methods, including light and electron microscopy, immunohistochemistry, in situ
Examples include hepatic zonation, where periportal and pericentral regions exhibit different metabolic functions; brain cortex versus
