Basilemma

/bæsɪˈlɛmə/ noun

Definition

The basement membrane or basal lamina, a thin layer of specialized tissue that forms the base of epithelial structures.

Etymology

From Greek 'basis' (base) + 'lemma' (thin skin, membrane). This anatomical term emerged in 19th-century histology and cell biology to describe foundational tissue layers.

Kelly Says

The basilemma is the 'skin of the base'—it's the glue that holds your cells in place, and if it breaks down, cancer cells can escape and spread, making it one of the most important structures in your body.
