Considering that Amoeba sp., among other animal cells, possesses the capacity of dynamic surface extensions containing actin filaments. These filaments produce pseudopodia-stubby distensions of the actin cortex-with which they walked over surfaces. Therefore if there is an interest in slowing down the movement we would have to be interested in fibroblast cells that regularly extend a thin, sheetlike process known as lamellipodium, which contains a dense meshwork of actin filaments. Moreover, actin filaments can form the so-called microspikes, which are about 0.1 um wide and 5 to 10 um long and contain a loose bundle of about 20 actin filaments oriented with their plus ends pointing outward. In conclusion, it will be a good idea to look at the actin protein in order to make a research in amoeba's locomotion processes.
Myosin
The two most important antimicrobial proteins are defensins and cathelicidins. Defensins are small cationic peptides that can bind to and disrupt the cell membranes of bacteria, fungi, and viruses. Cathelicidins are also cationic peptides that can kill microbes by disrupting their cell membranes and by modulating the immune response.
Membranes surround cells. There are no cells found in membranes. Membranes are composed mostly of lipids.
Mucous membranes.

No. They are polymers of actin that form 'filaments'. Membranes in eukaryotic cells are composed of a 'lipid bilayer'

There are four different membranes in the body that are related to tissue; cutaneous membranes, mucosal membranes, synovial membranes, and serous membranes.

There are two membranes. Those are outer and inner membranes.
