Explanation: 

Detailed explanation-1: -Overview. The 3 types of muscle tissue are cardiac, smooth, and skeletal. Cardiac muscle cells are located in the walls of the heart, appear striped (striated), and are under involuntary control.

Detailed explanation-2: -Cardiac muscles are a type of specialized, striated muscle found only in the heart. They are under the control of the autonomic nervous system, which means they are involuntary and work autonomously. They also contain blood vessels that supply nutrients to cardiac muscle tissue and remove waste products.

Detailed explanation-3: -Cardiac muscle tissue or myocardium forms the bulk of the heart. The heart wall is a three-layered structure with a thick layer of myocardium sandwiched between the inner endocardium and the outer epicardium (also known as the visceral pericardium).
