The membrane that surrounds the embryo and is filled with fluids that cushions and protects the embryo is called the amniotic sac or amnion.
The outer layer of the serous membrane that covers each testis is called the tunica vaginalis. It is a two-layered structure that surrounds and protects the testis within the scrotum.
It is called the vacuolar membrane.Sometimes it is referred to as the vacuole membrane. The membrane round the large central vacuole in plants it is also called the tonoplast.
The membrane is composed of a lipid bilayer that surrounds the cell, providing a barrier between the internal and external environment. It controls the entry and exit of molecules, allowing the cell to maintain internal conditions necessary for survival. Additionally, the membrane contains proteins that play a role in cell communication, adhesion, and transport.
The phospholipid bilayer that surrounds and maintains the integrity of a cell is called the cell membrane or plasma membrane. It acts as a barrier that controls the passage of substances in and out of the cell, allowing for the regulation of cellular activities.
A nuclear membrane, also called a nuclear envelope, surrounds the nucleus of a cell and separates it from the cytoplasm. It controls the passage of molecules in and out of the nucleus, helping to regulate gene expression and protect the genetic material within the nucleus.
The nuclear membrane is the thin boundary around the nucleus of a cell.
perinuclear membrane
The shiny membrane that lines the inside of the body wall in a dogfish is called the peritoneum. It is a thin serous membrane that surrounds and protects the internal organs within the body cavity.
Mucosa is a mucous membrane that lines the inside of the tract from mouth to anus. Depending upon the section of the digestive tract, it protects the GI tract wall, secretes substances, and absorbs the end products of digestion. It also surrounds the large and small intestines, and other vital organs in the human body
Eukaryotic cells have a double-layered membrane called the nuclear envelope that surrounds and protects the nucleus. Additionally, eukaryotic cells have a plasma membrane that encloses the entire cell and regulates the movement of substances in and out of the cell.

Periosteum surrounds and protects bones. It also is the site of healing, like with a fracture. If the periosteum grows abnormally, it is called Exostosis, like what forms splints.
