FAQ

Frequently Asked Questions

No, it is a highly specialised term used exclusively in cell biology, neuroscience, and related fields.

A filopodium is a thin, finger-like projection, while a lamellipodium is a broader, flat, sheet-like protrusion at the leading edge of a moving cell. Both are made of actin.

In highly technical literature, you might find the back-formation 'to filopodiate,' meaning to form filopodia, but it is very rare. The noun form is standard.

In British English: /ˌfɪlə(ʊ)ˈpəʊdɪə/. In American English: /ˌfɪloʊˈpoʊdiə/.
