The term "basal lamina" is usually used with electron microscopy, while the term "basement membrane" is usually used with light microscopy. The structure known as the basement membrane in light microscopy refers to the stained structure anchoring an epithelial layer. This encompasses the basal lamina secreted by epithelial cells and typically a reticular lamina secreted by other cells.
The basal lamina, made up of the lamina densa and the lamina lucida. In cases where to layers of epithelium abut one another, the basal lamina is referred to as a basement membrane.
Basal Lamina
basement membrane which is made up of the basal lamina and reticular lamina
lamina propia is a thin layer or plate that sits between the surface epithelium and the muscle layer. which can be found in the Mucosa layer of the alimentary canal
→ layers from alveolus to capillary ①surfactant layer (inside alveolus) ②pneumocyteⅠ(typeⅠ cell) layer ③fused basal lamina (consists of basal laminae of alveolar epithelium and capillary endothelium) ④endothelium (inside capillary)
The Mucosa layer contains lamina propia
A basal layer is the deepest layer of the epidermis.
A basal layer is the deepest layer of the epidermis.
