The muscular system is made up of over 600 muscles. These include three muscle types: smooth, skeletal, and cardiac. Only skeletal muscles are voluntary, meaning you can control them consciously.
Answer:
Muscle contraction is defined at the molecular level by myosin molecules bringing actin filaments together.
Explanation:
Researchers at Osaka University have created new electron cryomicroscopy images with remarkable resolution that reveal unusually substantial conformational changes in the myosin molecule during the pull.
What doesn't limit the range of moton from the things which you've mentioned would be age. Age per se doesn't really limit the range of motion - while there are factors which negatively influence our range of motion and which are strongly correlated with age, it is hard to say that age itself would be the cause of a limited range of motion.
