I'm no expert but one difference is your external abdominal muscles are voluntary and intestinal muscles are involuntary.
Leg muscles tend to be longer and less dense or compact than abdominal muscles. Leg muscles are also, of course, found on your legs. Abdominal muscles are shorter and more compact than leg muscles and are found on your torso, below the breasts down to the groin.
The main difference between the muscles involved in inspiration and expiration is that inspiration involves the diaphragm and external intercostal muscles, which contract to expand the chest cavity and draw air into the lungs. In contrast, expiration primarily involves the relaxation of these muscles, along with the internal intercostal muscles and abdominal muscles, which contract to compress the chest cavity and push air out of the lungs.
The muscles in the intestines are not named, specifically. There are circumferential muscle layers and longitudinal muscle layers in the intestines. These muscle layers create the peristalsis that moves food and digestive products through the intestinal tract. If you are asking the names of the muscles of the abdominal wall, they are the rectus abdominis, internal and external obliques, and the transverse abdominal muscles.

An abdominal wall is the layer of muscles which surrounds the abdominal cavity and contains the abdominal organs.
Reverse crunches primarily target the lower abdominal muscles, while leg raises target both the lower and upper abdominal muscles. Leg raises are generally more effective for overall abdominal muscle engagement, while reverse crunches are more focused on the lower abs.
The causes of loose abdominal muscles include extreme weight loss and pregnancy.
The baby is located behind the abdominal muscles, within the uterus, which is situated in the pelvic cavity. The abdominal muscles form a protective layer around the uterus and other internal organs. As the pregnancy progresses, the growing baby pushes against the abdominal wall, but it remains inside the uterus, separated from the abdominal muscles.
Yes, cycling can help improve abdominal muscles as it engages the core muscles while pedaling and maintaining balance on the bike. Regular cycling can contribute to strengthening and toning the abdominal muscles over time.
