Three Muscle Types (Skeletal, Smooth, and Cardiac)
There are three muscle types, striated, smooth, and cardiac. Muscles can be voluntary and involuntary; while skeletal muscles are voluntary, smooth and cardiac are not. Likewise skeletal muscles are the only muscle that is not self stimulating. Skeletal muscles also fatigue easily while all other muscle types don’t fatigue. Additionally cardiac and skeletal muscles are striated while skeletal muscles are not. Smooth and cardiac muscles are also self stimulating while skeletal muscles are not. Skeletal muscles are only under control of the nervous system while smooth and cardiac are under control of the endocrine system. Skeletal muscles are also the only muscles that are not rhythmic. Skeletal and cardiac muscle strength increase with stretching while smooth muscle strength does not increase with stretching. Each muscle type has different qualities that set them apart. Skeletal muscles are located on bones or close to skin while smooth line the walls of your internal organs and your cardiac is only found in you heart. They are also different in that skeletal muscles need high energy requirements and have the most amount of mitochondria to produce ATP, smooth needs low energy requirements and have the least amount of mitochondria since they don’t need ATP as much, and cardiac muscles need medium muscle requirements along with medium amounts of mitochondria and ATP production. Skeletal muscles are fast contracting muscles while smooth are slow and cardiac are intermediate.
