For centuries, the bones are considered as a dead structure that only serves to support the soft tissue surrounding active. The souls gradually realize that the bone alive and growing. Bone has its own blood vessels and is always built and reshaped.
Framework not only serves as a buffer body. The joints between bones that allows flexible bones move when the muscle pull. Framework also protects vital organs. For example, the skull protects the brain. Own bone calcium stores play a role, which is essential for the continuation of mineral working muscles and nerves. Bones also produce various types of blood cells. The framework contains cartilage (cartilage) that covers the ends of bones in the joints and become part of the system framework of the ears and nose. There is also cartilage between the sternum and ribs.
According to the shape and size, the bones can be divided into four main groups. Pipe bone, short bone, flat bone, and spine.
Axial framework includes the skull, spine, ribs, and sternum. The skull contains the brain and sensory organs such as the principal eyes, ears, tongue and nose.
Framework of the appendix consists of hand and foot bones, and bones tie that united them with other body parts. Hands and feet contain many tiny bones. With nimble hands can play and move the object. Legs help balance the body.

Teeth are strong bone structure that grew out of the soft gums. Teeth firmly in the upper jaw and lower jaw. Each tooth consists of the top and bottom. Adults have 32 teeth with various forms and functions. In each jaw there are four incisors (insisivus) chisel-shaped, useful for gripping and cutting food.
Two canine teeth (kaninus) pointed for piercing and tearing food, and four premolar teeth are flat, along with a large molar teeth, for crushing and chewing food. Humans have two sets of teeth along his life. The first set consists of 20 milk teeth, between the ages of 6 and 30 months. The second set consists of 32 pieces of permanent adult teeth lined up in the gums. Since the age of six years, adult teeth begin to appear, replace the milk teeth out one by one. The last permanent teeth are growing behind the molar teeth during adolescence.
Lips and front teeth pulled food into the mouth. Strong jaw muscles that move the lower jaw up and down to destroy the food was interrupted by a large molar teeth. Three pairs of salivary glands release saliva into the mouth, and tongue chewed food mixed saliva premises. Tongue pushing food slippery lump, called a bolus, into the esophagus. Bolus triggering reflex muscle contraction called peristalsis. This movement was encouraged chewed food into the abdominal cavity to digest at a later stage.

Insects known as animal species, amounting to the most. There are more than a million species we know. Insect body sizes ranging from small sizes of up to flea beetles the size of your palm. Insects have no bones, but a hard protective order on the outside called eksoskeleton.
All kinds of insects in general have the same body structure. Insects have three body parts: head, chest (thoracic), and stomach (abdominal). 
There are eyes in the head, jaw and sensory organs. In the chest there legs and wings. Insects have six legs and many have one or two pairs of wings. Abdomen is made up of the stomach, reproductive organs, and respiratory tract, called spirakula. Spirakula change lung function. As a result, the insect's body can not grow larger. If the body becomes bigger, the insect will die because the air can not be channeled through the body quickly.
Ants, termites and bees are social insects. They are members of a colony. Center of colony life is in a laying queen. While serving only males fertilize the new queens which fly elsewhere to establish new colonies. After mating, males will die. Social insects serve to build a complex structure of the house. Wasps made a nest of paper from plant materials in the chew. Honey bees build nests made of geometric cells of wax. While ants and termites make their nests from the ground.
Generally insects have two pairs of wings, except the worker ants and fleas. Beetles have wings, but not visible. Front wings transformed into the hard shell covering a soft rear wing, which used to fly.
Several kinds of insects, such as the African desert locust, is a very harmful pests. Locust invasion can damage the mob big fields within just a few hours. However, many types of insects that are beneficial to humans. Without the bees and other flying insects, pollination is unlikely to flower and produce fruit trees difficult.
The world record-breaking insect has exceptional. The sound of crickets can be heard at 500meter. Queen termite can live up to people's age, ie up to 50 years. Many species of insects can lift or drag objects that weigh 20 times their own weight. The largest insect is a winged butterflies Queen Alexandra bird measuring 20 inches stretched.

third of people age spent sleeping. During sleep, the human body and brain a rest is absorbed by processing information on the previous day. Sleep is a natural and important activities, as part of the wake cycle and slept for 24 hours. Sleep is a state of awareness over where someone can be easily awakened from sleep. The experts studied the behavior of some people using a tool called elektroensefalograf (EEG) to measure brain waves.
At the moment we are sleeping or awake, the brain waves generated by the constant 'electro traffic' is busy passing through the billions of neurons in the brain. Brain waves are generated by a person running awake, alert, drowsy, or asleep. Dreams are the events experienced by a person during sleep.
Sleep patterns following a specific sequence of events, which can repeat itself. When asleep, we experience four stages of sleep, ranging from semi-conscious stage to stage of deep sleep or slow eye flicker or NREM (nonrapid-eye-movement). Heart rate and respiratory rate decreased and brain activity slows.
After 90 minutes, sleep stage switch to a floating stage or rapid eye flicker or REM (rapid-eye-movement). The eyes move under the eyelids and the dream took place. The rate of respiration and heart rate continued to increase, and increased brain activity. The body does not move and the muscles in a paralyzed state. Interval of five minutes to ten minutes, going back sipenidur experience deep sleep. This pattern along tonight repeated up to five times with the REM sleep phase intervals starting every 90 minutes. Sleep period of continued shortened in all night, and REM sleep periods so long. Last REM period lasted up to 50 minutes.
