What are the two portions of the basement membrane and from where are they derived?

Explanation:
The basement membrane has two layers: the basal lamina and the lamina reticularis. The basal lamina is secreted by the epithelial cells themselves, forming the layer closest to the epithelium. The lamina reticularis lies beneath it and is produced by the connective tissue, mainly by fibroblasts. This arrangement anchors the epithelium to the underlying connective tissue and helps organize tissue structure. So, the basal lamina comes from epithelial tissue, and the lamina reticularis comes from connective tissue.
