gastric mucosa
In a fetal pig, the stomach is located in the upper part of the abdomen, below the diaphragm and between the esophagus and the small intestine. The inner surface of the fetal pig's stomach is lined with mucous membrane, which is composed of rugae (folds) that help expand the stomach to accommodate food and aid in digestion.
The infoldings of the inner membrane of the mitochondria are called cristae. These structures increase the surface area of the inner membrane, allowing for more space for chemical reactions involved in cellular respiration to take place.
cell membrane aka plasma membrane
The innermost layer of the stomach is made of mucous membrane. The mucous membrane of the stomach contains simple columnar epithelium tissue, that has many exocrine cells.
omentum
Peritoneum is the serous membrane that covers the lining of the stomach.
visceral peritoneum
ruga
The diffrence is that the cell membrane is just a barrier between the exterior enviroment and the interior of the cell, while the cell surface membrane exerts control over what enters/leaves the cell! :)
The protein that projects from the outer surface of the membrane is termed as an extrinsic or peripheral membrane protein. These proteins are not embedded within the lipid bilayer but instead are attached to the surface of the membrane.
The [mucosal] Pleural membrane.
The folds of mucus in the stomach are known as rugae. These folds allow the stomach to expand when it fills with food and help increase the surface area for gastric secretions. Rugae are lined with a mucous membrane that protects the stomach wall from the acidic environment and aids in the initial stages of digestion. When the stomach empties, the folds flatten out, enabling the organ to return to its smaller size.
