Ectoplasm (cell biology)

Ectoplasm (also exoplasm) (from the ancient Greek words ἐκτός (èktòs): outside and πλάσμα: plasma, literally meaning: that which has form) is the non-granulated outer part of a cell's cytoplasm, while endoplasm is its often granulated inner layer. It is clear, and protects as well as transports things within the cell.[1] Moreover, large numbers of actin filaments frequently occur in the ectoplasm, which form an elastic support for the cell membrane.[2]

It contains actin and myosin microfilaments.
