The real name for stomach muscles is the rectus abdominis. This muscle is part of the core and runs vertically along the front of the abdomen. Additionally, the abdominal region includes other muscles such as the obliques and the transverse abdominis, which play important roles in stability and movement.

Muscles, fat, and water.
Gastric muscularis is a general term for the muscular layer of the stomach. It is made up of a group of muscles, each with their own name. Muscularis externa is also used to describe the stomach muscles. It differs from the other gastrointestinal organs in that it has 3 layers of smooth muscle instead of two. Please keep in mind that "stomach" muscles in anatomy are different from abdominal muscles. Many people refer to toning the abdominal region as getting a "hard stomach".
It is most definitely involuntary. You do not have to make your stomach contract every time you eat something.
