Gastric Fundus Smooth Muscle

Molecular classification
Smooth Muscle Tissue
01

Overview

The gastric fundus smooth muscle refers to the specialized smooth muscle tissue located in the fundus, the upper part of the stomach. It plays a critical role in accommodating ingested food through receptive relaxation and regulating gastric motility through coordinated contraction and relaxation. Its function is modulated by neural, hormonal, and paracrine signaling pathways.

Mechanism of action

Varies depending on the drug. Cholinergics increase contractility. Nitric oxide donors and adenosine receptor agonists promote relaxation. ROCK inhibitors reduce contractile tone. Potassium channel openers modulate membrane potential.
