God has created human (man/woman) most intelligent then other animals in the world. He has given a flexible body. Every animal has four legs and no arms, only human has two legs and two arms and a very complicated body. It functions systematically. If this system fails to function in any way then he has to take medicines to correct the system.
It is said that morning sunrays give vitamins; the sky is red in the morning and also in the evening, and blue in the afternoon. It is good for health if a person walks in the morning and get fresh air especially in the garden where lots of flowers and green plants and trees are present. A student study in the morning can memorize faster than study in the afternoon or at night.
Skull: Skull is the most important part. The human brain and soul is in the skull. Every part of the body functions after getting signals from the brain. It communicates all parts of body through nervous system. Normally a person can get stroke if skull gets injured. It is very common after car accidents.
The skull is one of the principle groups of bones in the human anatomy. The skull consists of twenty-six bones: eight bones form the cranium, which houses the brain and ear ossicles, plus fourteen facial bones, which form the front of the face, jaw, nose, orbits, and the roof of the mouth, three more bones make up the inner ear ossicles, and one more, the hyoid bone, is in the neck and is attached to the temporal bone by ligaments and anchors the tongue. The skull also contains a dental arcade of teeth, which are technically not bones, though they do share some of the compositional characteristics of bone tissue. The bones of the skull include the frontal bone (which makes up the forehead and roof of the orbits), the occipital bone (which forms the back and base of the skull), two parietal bones (which form the roof and upper sides of the skull), and two temporal bones (which form the lower sides of the skull and house the inner ear ossicles). The lower rearmost part of each temporal bone is called the mastoid process, but because it is separated from the temporal bone, proper, by a suture, it is often considered a separate bone. The sphenoid bone forms the central base of the skull and spans the skull from side to side, the greater wings forming side plates of the skull.
Backbone (Spine): It is the structure of bone surrounding and protecting the spinal cord in vertebrate animals. It is also called a vertebral column, spine, or backbone. Backbone is the center of human body. It is a very complicated part. It has many bones connected to it. One end connect to neck and other side it goes all the way to tail bone. Many people have back pain problem because any wrong movement of your body can starts this back pain and it can be very painful. It is said that a person starts shrinking after age 50-55. This happens because backbones work like a spring. A person starts getting week after age 55 and these backbones expanding earlier starts shrinking. Human height starts shrinking in old age. Researchers also found that even in young life this process of expanding and shrinking takes place. When a person is sleeping at night, he relaxes his body then these bones expand during his sleep. When he wakes up in the morning his height is increase. During the day man works and body gets tired and these bones gets tense, these bones shrink during the day. This process repeats every day. In young age it expands more and in old age it shrinks more.
