THE BONES AND MUSCLES

 Our body is composed of more than 600 muscles and 206 bones embedded with each other and joined them... Well, except the hyoid bone, which is under the tongue and is the only one that is not attached to any bone and it is suspended in the area close to jaw attached by ligaments and muscles.

 

When we walk, when we laugh, when we raise hand or open or close our eyes our muscles are working, together with the bones of the skeleton by tendons.  And it is only to step over 200 muscles are used. 

I'm going to tell some interesting curiosities in this regard: 

 

The first cervical vertebra is called as a reference to the mythological titan Atlas. He was sentenced by Zeus to hold the pillars that separate the Earth from the heavens on his shoulders. It is named by analogy, to be the vertebra supporting the skull.

 

 

 

 

When we got up from the bed, we tend to measure something less than one centimeter more than the evening. This is because while we're asleep intervertebral discs are expanded, and will crush during the day when we are upright. 

 

 

Some people are born with a some rib extra. Known as the "cervical rib" or "costilla de Eva" is located above the first sternal rib. 

 

Movement strengthens the bones and develops the muscles, and it is important to exercise at all ages. Do you remember this video?
