The term for the inner portion of an organ is called the "medulla." In various organs, the medulla can refer to the innermost part, such as the medulla of the adrenal gland or the medulla oblongata in the brain. This inner region often has distinct functions compared to the outer layers of the organ.

Epithelial tissue, or skin.
The inner wall of the stomach is folded into many furrows called rugae (any fold, ridge, or furrow found within an organ). At the bottom of these folds are the secretary cells called the gastric pits ( Cells located at the bottom of rugae within the stomach). These are surrounded by a thick protective layer of mucus. This mucus on the inner wall of your stomach protects you from Hydrochloric acid (a clear, colorless, liquid with a strong, sharp odor and strongly acidic taste) from burning a hole in your stomach.
The organ in the abdominal cavity that has folds similar to those in the stomach wall is the small intestine. The inner lining of the small intestine features folds called plicae circulares, which increase the surface area for absorption, much like the rugae in the stomach that allow for expansion and enhance gastric function. Both structures serve to optimize their respective organ functions through increased surface area.
The specific organ of hearing is called the ear. It consists of three main parts: outer ear, middle ear, and inner ear, each playing a distinct role in the process of hearing.

The inner wall is the "endocardium"
