Teachers and administrators study course design to ensure that: 1  What the department is obligated to teach in a given course at a given level in a given program is actually taught. 2  The alignment of intention of the course, instruction, and assessment are clear and firmly aligned.
Cardiac muscle (heart muscle) is involuntary striated muscle that is found in the walls and histological foundation of the heart, specifically the myocardium. Cardiac muscle is one of three major types of muscle, the others being skeletal and smooth muscle.ardiac muscle cells, unlike most other tissues in the body, rely on an available blood and electrical supply to deliver oxygen and nutrients and remove waste products such as carbon dioxide. The coronary arteries help fulfill this function.
Cardiac muscles and skeletal muscles are also different in their shape. While the cardiac muscles are semi-spindle, the skeletal muscles are cylindrical in shape. Another difference is that the cardiac muscles are short in comparison to skeletal muscles.The skeletal muscles are attached to the bone through tendons. The skeletal muscles also contain myoblasts, which form the fibers in the muscles. The cardiac muscles are seen in the myocardium of the heart.hen looking at the T-tubules, the skeletal muscles contain more of it than the cardiac muscles. Moreover, the T-tubules in cardiac muscles are also wider. Summary. 1. Cardiac muscles are involuntarily controlled, whereas the somatic nervous system controls the movement of the skeletal muscles.
