Explanation: How Our Muscles Work

This is explanation is going to explain how muscles in the human body work.

The average human has the same amount of muscles which is over 600 muscles, and they all belong to a particular group like the smooth muscles, the cardiac muscles and the skeletal muscles.  

The smooth muscles are mostly the respiratory system and the digestive system, like when you eat something the smooth muscles push the food down as it’s being digested and the muscles push the food out when you are going to vomit and other reasons is that the smooth muscles also help us in other ways like when we want to pee the smooth muscles help hold it inside.

Now the cardiac muscles or in other ways they are called involuntary which means they work when you’re not even trying, one of the cardiac muscles is the heart which pumps blood through the rest of our body, which means you don’t have to tell it what to do it just does it by itself.

The skeletal muscles or they are also called voluntary which means you have to move them yourself and it dosen’t work by themselves, they’re controlled by different parts of the brain like the cerebral motor cortex and the cerebellum, the brain which sends an electrical signal down the spin and on to where it moves which causes them to contract, and the message is sent back to the brain which is smooth.

There are different muscles that are named different like the deltoids which are the shoulders, the pectorals or you could call them pecs, the quadriceps which are the thighs and the gluteus maximus which is the rear end, also kids don’t even have to work out they have to just keep eating healthy food and keep the bones healthy for more simple things like running or riding a bike.

Now you know all the muscles you could name them to a doctor.
