The Musculoskeletal System

Hello friends! Welcome to a new Happy Learning video.
Today, we’re going to learn about the human musculoskeletal system, It’s what lets us move around!
The musculoskeletal system, is made up of two systems, the muscular system, and the skeletal system.
The muscular system is the active part of the musculoskeletal system. Muscles are between our bones and skin and they are joined to the bones through tendons. They are elastic organs that can be lengthened, or shortened, causing some body part movement. Us humans, have approximately 630 muscles.
According to the movements that they make, we can differentiate, voluntary and involuntary muscles. Voluntary muscles move only when we want them to and the involuntary muscles are those that move without us realising, like our heart or stomach, that are always in movement.
The skeletal system is made up of all bones and cartilage. The Skeleton gives us our shape, that differentiates us from other living things and allows us to walk, run or jump. Our body has 206 bones and each one of them has their own name. Some of them are, skull, that protects our brain, the spine, that maintains us stable and upright, the jaw, allows us to move our mouths to chew food, Ribs, that protect our heart or lungs and femur, the longest bone in the human body and is found in our legs.
Bones are joined with each other by joints.
They are divided into three groups, depending on their level of mobility:
Immobile or fixed joints, don’t have any mobility, like the ones that join the skull.
Semi-mobile joints, that do have some mobility, but not a lot, like vertebrae (vertebri) in our backs.
Mobile joints, that have great mobility, like our elbow or knee.
Now we’ve got to know a little more about our musculoskeletal system. Now, we need to do plenty of physical exercise to make it work brilliantly and maintain ourselves really healthy.
