Which muscle is not found in the cat chest?
The pectoralis major muscle is not found in the cat chest.
The muscle that is not found in the cat chest is the diaphragm. While the diaphragm is a large dome-shaped muscle that separates the chest cavity from the abdominal cavity in humans and some other mammals, it is relatively small and not well-developed in cats.
To determine which muscle is not found in the cat chest, we can start by understanding the anatomy of a cat's chest.
The chest of a cat, also known as the thorax, is composed of numerous muscles that are involved in respiration and movement. These muscles include the pectoral muscles, intercostal muscles, and diaphragm.
The pectoral muscles, specifically the pectoralis major and pectoralis minor, are major muscles located in the chest area. These muscles are responsible for the movement of the cat's forelimbs.
The intercostal muscles are located between the ribs and are responsible for the expansion and contraction of the ribcage during breathing.
The diaphragm is a dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a significant role in the process of respiration, as it contracts and relaxes to help control the flow of air in and out of the lungs.
Considering the muscles mentioned above, it can be concluded that the muscle NOT found in the cat chest is the deltoid muscle. The deltoid muscle is located in the shoulder region and is responsible for the movement and stabilization of the shoulder joint. While it plays a crucial role in the movement of the forelimb, it is not located within the cat's chest region.
