visceral smooth muscle tissue

Visceral smooth muscle tissue is the smooth muscle component of organ walls in the esophagus, stomach, and intestines, capable of sustained contraction under autonomic control.

Located in the middle and lower esophagus, throughout the stomach and intestines in the muscularis propria layer, and in many other hollow organs.

Visceral smooth muscle generates coordinated peristaltic contractions that propel contents through the digestive tract and maintains organ tone.

Visceral smooth muscle receives autonomic innervation through myenteric plexuses and is regulated by hormonal signals from the gut.

Dysfunction occurs in conditions like irritable bowel syndrome, achalasia, and pseudo-obstruction, impairing normal digestive function.
