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.
