The diaphragm is the main respiratory muscle. Along with other respiratory muscles, the diaphragm is responsible for the muscular contraction that generates the respiratory cycle and, as a consequence, the gaseous interchanges in the lungs. Guinea pigs ( Cavia porcellus Linnaeus 1758) are largely used as experimental animals in many biology applications due to their easy management, low cost, and docile behavior. As the diaphragm exerts important effects on lung physiology and function, this study aimed at investigating the morphological characteristics of the muscle, through macroscopic, microscopic, and scanning electron microscopy to add reference data for future studies. We observed a “U”‐shaped tendineous center and its morphology was similar to other mammals. These results cooperate with the descriptive and comparative anatomy of mammals, besides can be used as control data for areas of surgery and stem cells. Microsc. Res.
