Definition of filopodium in English:

filopodium

noun

Biology
  • A long, slender, tapering pseudopodium, as found in some protozoans and in embryonic cells.

    • ‘These filopodia push into adjacent cells and are ingested by them.’
    • ‘A few hours after it detached, the cell regenerated its filopodia and once again adhered to the matrix.’
    • ‘In some cells, filopodia are essential for navigation: when filopodia are suppressed, the nerve growth cones can advance but cannot navigate.’
    • ‘If a skill is used again and again, the link hardens; if it's used only once, the filopodia soon shrink back, triggering a change in the brain cell, a thinning of the grip that may explain forgetting.’
    • ‘Simultaneously, the actin bundles within filopodia disappear, followed by retraction of these surface extensions.’

Origin
