APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Smooth muscle is present throughout the body, where it serves a variety of functions. It is in the stomach and intestines, where it helps with digestion and nutrient collection.

Detailed explanation-2: -Layers of Stomach Wall The three layers of smooth muscle consist of the outer longitudinal, the middle circular, and the inner oblique muscles. Construction of these muscles helps mix and break the contents into a suspension of nutrients called chyme and propels it into the duodenum.

Detailed explanation-3: -Gastrointestinal smooth muscles are ‘autonomous’ and generate spontaneous electrical activity (slow waves) that does not depend upon input from nerves. Intrinsic pacemaker activity comes from interstitial cells of Cajal, which are electrically coupled to smooth muscle cells.

Detailed explanation-4: -Smooth muscle – located in various internal structures including the digestive tract, uterus and blood vessels such as arteries.
