A muscle is made up of hundreds of thousands of cells, specially conditioned to be able to tighten in on themselves, and relax, that allows free control of muscles, as bones, pivoting on the joints, are moved by the contractions.
Muscles often work in pairs so that they can pull in different or opposite directions. The cells that make up muscles contract and then relax back to its original size. Tiny microscopic fibers in these cells compress by sliding past each other like a sliding door being opened & shut again. While this happens, calcium rises which sends messages to the brain to regulator proteins which pull at each other causing motion.
Muscles work by contractile units called sarcomeres. They are arranged in parallel rows in your skeletal muscles and use joints that act as levers to move your body.
Your muscles are attached to bones and other muscles via tendons and ligaments to enable movement throughout the body.
it is a function in which others despose of their waste into a lover/parters mouth.
it does it's job by being a good little boy instead of a naughty little sh*t
muscular System
The nervous system, the skeletal system, and the muscular system.
The Muscular, Digestive, and Integumentary system.
it works with the skeletal system ...THE END... thank you...i think :)
Our muscles are fastened to the skeleton so that we can move our limbs.
The muscular system and the cardiovascular system interact with each other by the fact that the cardiovascular system provides the muscular cell with oxygen & food, to give them energy so these muscles can move. (Try run while holding your breath hard right?)
the skeletal system give blood from the heart to the circulatory system to keep homeostasis

your stupid you do not need to no it
you mean how does the circulatory system interact with the muscular system? The heart is made of cardiac muscle that allows it to beat and the blood vessels have smooth muscle in them that help them constrict or dilate. And, the other way around, the circulatory system provides the fuel in the form of glucose and oxygen so that the muscles can do their work.^^ ~fayechums~
