Muscular disorders affect the muscular system, which is responsible for movement and maintaining posture. Muscular disorders can affect various parts of the muscular system, including:
1. Skeletal muscles: These are the muscles that attach to bones and enable movement of the body. Muscular disorders affecting skeletal muscles can lead to weakness, stiffness, cramps, and pain.
2. Smooth muscles: These are the muscles that line the walls of organs and blood vessels. Muscular disorders affecting smooth muscles can lead to problems with digestion, urination, and blood pressure regulation.
3. Cardiac muscle: This is the specialized muscle that makes up the heart. Muscular disorders affecting the cardiac muscle can lead to heart failure, arrhythmias, and other cardiovascular problems.
Examples of muscular disorders include muscular dystrophy, myasthenia gravis, fibromyalgia, and multiple sclerosis.
