Our muscular system is made of more than 600 muscles, muscles are made of one of the 4 tissues composing our body… muscular tissue (as you know from a previous article, tissues originate (as anatomic definition!) when cells with a similar function organize together to perform that function http://www.alexcanazei.yoga/2013/08/12/biology-and-union/).
There are 3 major types of muscles:
1- Striated or skeletal, they can be voluntarily controlled to move the body, perform activities or mantain the posture
2- Smooth or involuntary, typical of your internal organs, for example they move the food inside your stomach and intestine during digestion. Breathing and blood circulation are assisted by smooth muscles
3- Cardiac, striated muscles that work on an involuntary basis, the tissues composing our heart!
Here i’ll refer mainly to striated/skeletal muscles!
What’s the basic structure of our muscles?
