这是个拉丁文的生物学词汇，pseudo是个前缀，意识就是“假的，模拟的”；podia是突起支撑的意思。合并起来就是“伪足”。

这个也太专业了，给你一段英文，自己看吧。
Pseudopods or pseudopodia (singular: pseudopodium) (from the Greek word ψευδοπόδια, ψευδός "fake, false" + πόδια "feet") are temporary projections of eukaryotic cells or unicellular protists. Cells that possess this faculty are generally referred to as amoeboids. Pseudopodia extend and contract by the reversible assembly of actin subunits into microfilaments. Filaments near the cell's end interact with myosin which causes contraction. The pseudopodium extends itself until the actin reassembles itself into a network. This is how amoebas move, as well as some cells found in animals, such as white blood cells. They are most commonly found on eubacteria.
