Questions: Which types of muscle can be conditioned to improve their function? Cardiac and skeletal muscle Smooth and rough muscle

The answer is the first one: cardiac and skeletal muscle.

Explanation:

1. Cardiac Muscle: This type of muscle is found in the heart. While it is not under voluntary control, it can be conditioned to improve its function through regular cardiovascular exercise. This type of exercise can enhance the efficiency and endurance of the heart muscle, improving overall cardiovascular health.

2. Skeletal Muscle: These muscles are under voluntary control and are responsible for movement. They can be conditioned through various forms of exercise, such as strength training and endurance activities. Conditioning skeletal muscles can increase their strength, size, endurance, and overall function.

3. Smooth Muscle: This type of muscle is found in the walls of internal organs and blood vessels. It is not typically conditioned through exercise in the same way as cardiac and skeletal muscles. While certain activities and lifestyle changes can influence the function of smooth muscle (e.g., diet affecting digestive smooth muscle), it is not directly conditioned through exercise.

4. Rough Muscle: There is no such classification as "rough muscle" in human anatomy. This term might be a misunderstanding or mislabeling.

In summary, cardiac and skeletal muscles can be conditioned to improve their function through appropriate exercise and training.
