Without the skeleton to give leverage, movement would be greatly restricted. However, biologically speaking, the skeleton does not enable movement. Protection, the skeleton protects many vital organ s: * The skull protects the brain, the eyes, and book the middle and inner ears. The spine protects the spinal cord. The rib cage, spine, and sternum protect the lungs, heart and major blood vessels. The clavicle and scapula protect the shoulder. The ilium and spine protect the digestive and urogenital systems and the hip. The patella and the ulna protect the knee and the elbow respectively.
Because the lower limbs have to bear the weight of the human body mdash; reaction forces at the feet can be 5-10 times the body weight during sprinting and jumping mdash; the bones of the pelvic girdle, the thigh, and the lower leg are massive. Similarly, and in contrast to the elbow, in the knee the kneecap, a sesamoid bone formed in the tendon of the large quadriceps muscles of the thigh, protects the knee from damage while helping the muscles in extending the knee. In each ankle there are 7 tarsal bones, including the heel bone, and in each foot 5 metatarsal bones and 14 phalanges. Function, the skeleton has six main functions: upport, the skeleton provides the framework which supports the body, and maintains its shape.

The axial skeleton transmits the weight from the head, the trunk, and the upper extremities down to the lower extremities at the hip joints, and is therefore responsible for the upright position of the human body. Most of the body weight is located in front of the spinal column which therefore have the erector spinae muscles and a large amount of ligaments attached to it resulting in the curved shape of the spine. The 240 skeletal muscles acting on the axial skeleton position the spine, allowing for small movements in the thoracic cage for breathing, and the head, where they control the minute and complex facial movements. The appendicular skeleton (126 bones) is subdivided into the upper and lower extremities : The axial skeleton is connected to the upper extremity (60) through the pectoral girdle (4) and to the lower extremity (60) through the pelvic girdle (2). Some 300 muscles attach to the appendicular skeleton. The only joint between the pectoral girdle and the thorax is between the clavicle and the sternum (i.e.

The distal ends of the forearm bones form the wrist joints with wallpaper the hand. In the hand, eight carpal bones arranged in two rows articulate with the metacarpal bones of the palm which articulate with the 14 finger bones (the phalanges ).

It was so well written that it seemed like i was looking at a picture album rather than making it up in my mind, even though I was. I think that the setting of the story also makes the story more adventurous because it is unfamiliar territory it makes it exciting to guess what? S going to happen next for the reader. Also from watching. W.II documentaries I have a idea of what the characters look like and what the planes and ships look like. I also found that the author did a great job in the characterization of Mallory.
Mallory is portrayed as a pretty decent smart man who was sort of the skeleton of the group, he kept the group all together as one. Yet he was a reasonable man as well, like when Stevens got his leg broken and it became infected he didn? T want the boy to die but he also didn? T want the rest of the group to die either from Stevens holding the group back. But, he only gave up on him when the infection was at its peak and Stevens was going to die soon. That was a pretty honest and noble thing to do to wait until the end for his friend. Although that book had a very, very slow start to it and it was very, very long it managed to turn out to be a very interesting story once you got past the first five chapters and I would recommend it to others only.
