The Schwann cell forms a myelin sheath around the axon of the nerve.

cell membrane
The part of an animal cell that forms a thin layer around the outside is the plasma membrane, also known as the cell membrane. This semi-permeable membrane is primarily composed of a phospholipid bilayer with embedded proteins, which helps regulate the movement of substances in and out of the cell. It also plays a key role in cell communication and signaling.
A vesicle forms as a small sac from the cell's membrane.
The answer is proteins.
The layer of bedrock near Earth's surface that forms a continuous shell around the Earth is called the lithosphere. This layer includes the crust and upper part of the mantle and is divided into tectonic plates that move and interact with each other.

The umbo, also known as the beak, is the oldest part of a clam shell. It is the point where growth starts and forms the center of the shell. Over time, new layers of shell material are added, extending outwards from the umbo.
