The mucous membranes (or mucosae; singular mucosa) are linings of mostly endodermal origin, covered in epithelium, which are involved in absorption and secretion. They line various body cavities that are exposed to the external environment and internal organs. They are at several places continuous with skin: at the nostrils, the lips, the ears, the genital area, and the anus. The sticky, thick fluid secreted by the mucous membranes and glands is termed mucus. The term mucous membrane refers to where they are found in the bodyand not every mucous membrane secretes mucus.
Body cavities featuring mucous membrane include most of the respiratory system. The glans penis (head of the penis) and glans clitoridis, along with the inside of the prepuce (foreskin) and the clitoral hood, are mucous membranes. The urethra is also a mucous membrane. The secreted mucus traps the pathogens in the body, preventing any further activities of diseases.
An example of a mucous membrane is the lining of the respiratory tract, which includes the nose, throat, and lungs. These membranes secrete mucus, providing lubrication and protection against pathogens and irritants. Mucous membranes are also found in other areas of the body, such as the digestive tract and reproductive organs.

Both -ium or -eum mean membrane.
If you mean the cell membrane, it keeps lets things in and out of the cell.
If by outer membrane you mean cell wall, then yes.

Assuming by nuclear membrane, you mean the membrane that surrounds the nucleus of cells, then nuclear membrane are found keeping the tidbits of cell nuclei together in the middle of the cytoplasm of the cell.
when an organelle is membrane bound that means that the organelle has a protective shield around it.
The cell membrane only allows certain molecules through.
Birthsop is the afterbirth or the membrane of the baby.

The respiratory system is lined with a mucous membrane that secretes mucus.
