A: In biology, the Cell Membrane is a thin layer between the surrounding area and the cell's inside. It consists of Phospholipides (Soapy molecules) and Cholesterol (The Anti-advertised body chemical) and a whole lot of proteins. Theoretically, it's liquid. the fact the body doesn't collapse is just because of the hard skin on the outside and the hard bones and some gelitine and solid proteins inside.

B: For internet lolz and retard understanding, see the other description
There are thousands of proteins in and on the Cell Membrane of just a simple muscle cell.
