Smooth muscle is responsible for the contraction that moves limbs.
The arrector pili muscle is responsible for causing hair to stand on end when contracted. It is a small bundle of smooth muscle fibers attached to the hair follicle. When this muscle contracts, it pulls on the hair follicle, making the hair upright.
Hair is not held in by muscles, but there are muscles that an erect a hair called the "arrector pili muscle".
they relate because they dont move. ivoluntary muscle means that they dont move. the smooth muscle doesnt move at all only the skeletal muscle does.
To move a voluntary muscle, you just want to do it. When you want to walk, the nervous system sends a signal to the brain and the skeletal muscle to move your legs. So you are making your leg move by voluntary muscle, which is skeletal muscle.
When you want to move a muscle, your brain sends a message out to the muscle you want to move, and the muscle sends a message back to your brain that your moving it and where.
