microspikes

microspikes
Projections from the leading edge of some cells, particularly, but not exclusively, nerve growth cones. They are usually about 100nm diameter, 5-10 m m long, and are supported by loosely bundled microfilaments. They are referred to by some authors as filopodia. Functionally a sort of linear version of a ruffle on a leading lamella.
