1.Skeletal muscles are attached to the bones. Smooth muscles line up the visceral organs viz. Intestines,blood vessels,pupils etc (therefore also known as visceral muscles.) 2.Skeletal muscles perform voluntary actions. Smooth muscles are responsible for involuntary reflexes and actions.
Skeletal muscle fibre type. Not all fibres within Skeletal muscles are the same. Different fibre types contract at different speeds, are suited to different types of activity and vary in colour depending on their Myoglobin (an oxygen carrying protein) content.
