The answer to your first question involves a connection between your actions and your brain. Your bones and muscles work together through a series of impulses and signals communicated between the brain and skeletal muscles. In order to move, the nervous system then sends signals a skeletal muscle to contract. When the muscle contracts, this movement causes the attached bone to follow.
And as for your second question,
The muscle tissue in your heart is cardiac, the muscle tissue in your blood vessels is smooth, and the muscle tissue in your toes is skeletal.
I hope this helps you, have a nice day!
