The Miracles beside Human Creation

       

The creation of man is an incredible miracle. He is the God who created man from a drop of semen. Travel before it is born into the world of human creation is very long, complex and very amazing magic. In brief, the human journey is a single cell in the mother's womb is weak, and smaller than a grain of salt, the cell divides into two, four, and sixteen. These cells continually divide and become a piece of meat. Then the lump of meat into a particular shape. Form the arms, legs, eyes. The first miracle of human creation is in the body of a woman's ovary organ section contained egg cell (ovum) cell maturation process of egg maturation experience then move into an organ called the fallopian tubes and traveled far to finally get to the womb of the mother. God created everything in such a way that the egg can travel through the fallopian tubes to get to the womb of the mother. If  the cells are not fertilized for about 24 hours, eggs cell will die. So it  needs sperm in the male body which is produced in the testes to fertilize it. Sperm will fertilize the egg cells and carry 23 chromosomes which  contains all information about the human body even to the very detail information is also stored in this chromosome. To be human 23 chromosomes sperm cells from the father must be united with 23 chromosomes in the mother cell. But the journey of sperm to fertilize an egg cell is not easy, about 250 million sperm which have been sent into the womb of the mother will die immediately. Only the number of sperm that had escaped into the womb of the mother and reach the entrance to the fallopian tubes. About 100 sperm and egg can meet egg cell and it was only 1 sperm cell  allowed unite eggs cell  which managed to bring the body's genetic data from the father. Two sets of genetic information from father and mother then combined with one another and eventually united into one cell in which there is all the information on unborn human beings from the eyes, complexion, color of hair and all forms of physical characteristics. Immediately after fertilization the cells divide into two new cells and then split again into 4 cells. Cells that continue to divide running in the fallopian tubes, collection of cells is known as a zygote. at the time of the cells in the zygote to divide and multiply, there was a miracle in which some cells start to grow differently from the other. The cells are in the middle will form the embryo, and the cells around it will form the placenta that feeds the developing embryo. After about 4 days after fertilization the zygote will patch and be planted in the mother's uterine wall. And the new creature that is embryo begins to grow. Cells that do not have consciousness begins to form the internal organs, skeletal and brain. At first, these cells used with each other each other become brain cells. After that other cells form the heart and after that the heart is formed. Then other cells separate to form blood vessels. Then in the fifth week of the hands and feet of the embryo begins to form from arms, fingers, feet and toe face began to form on the stage of 4 weeks, then began to eye on the hole formed in the face of it at week six . then formed ears. Along with the increase in the month, the baby in the mother's abdomen and then grow by taking a certain shape, and he was ready to begin life outside the world and it came on the last stage of birth. The baby will be born through the birth and the mother's pelvic bone. At the time of the birth of a baby's skull bones are soft and stretch created to protect the pins when going out. Then after the birth of the bones are hardening.

The composition of the human nervous system

            The nervous system has the functions and roles are very important for living things. Nervous system collect and process information, react to various stimuli and also arranged a variety of cells. Relation to the disciplines of psychology of the nervous system is also a driver of behavior. For example stimulus received a bad news and then he became upset and sad feelings are manifested in crying, it is a small example of how the nervous system plays a very important role in human behavior. The nervous system was essentially divided into two namely: 1) The central nervous system and 2) Peripheral nervous system. A. Central nervous system
           Central nervous system has the function of receiving, processing and interpreting or interpreting and storing sensory information coming from sensory nerves like the taste, sound, smell, color and pressure on the skin, internal organs and glands others. Central nervous system also functions to send messages to muscles, glands and internal organs. Central nervous system has two components, namely the brain and spinal marrow (spinal cord)

 

1) Brain The brain regulates all human activities. The brain is located in the skull cavity and covered by three layers of meninges membrane that is strong. Outermost membrane called the dura mater, the innermost and the middle is piamater called arachnoid. Among the three membranes that are fluid called cerebrospinal function is to reduce the impact or shock. The human brain is divided into three parts, namely a large brain (cerebrum), cerebellum (cerebellum) and advanced marrow.
a) big brain (cerebrum) Cerebrum has a surface that folds and is divided into two parts. The left hemisphere to serve the body right and the right hemisphere to serve the body left. The cerebrum consists of two layers. Gray outer layer called the cortex, containing the bodies of nerve cells. The inner layer contains white nerve fibers (neurit / axons). Big brain serves as a center of conscious activities such as thinking, remembering, talking, seeing, hearing, and moving.
b) Little Brain (Cerebellum) The cerebellum is located under the rear of the cerebrum. Small brain structures such as large brain. Consisting of the right and left hemispheres. Right and left hemispheres of the cerebellum are connected by bridges Varol. Divided into two layers as outer layers of the cerebrum that is gray and white inner layer. The cerebellum serves to regulate the body's balance and coordinate the muscles work when we move. c) advanced Marrow Advanced marrow (medulla oblongata) is divided into two layers, namely layers in the gray because it contains a lot of weight nerve cells and the outer layer is white because it contains neurit (axons). Advanced marrow serves as the central control of breathing, blood vessels constrict, regulate heartbeat, regulate body temperature and other activities that are not realized.
2). Spinal cord (spinal cord)
Is an extension of the brain. Bemula spinal cord from the base of the brain, then ran along the middle of the back and protected by the backbone. Spinal nerves have a role as a bridge that connects the brain to other parts of the body that lies below the neck. Spinal cord is capable of producing reflex movements automatically without any help from the brain and without involving conscious effort. For example, when a person touches the iron unwitting intentionally he will pull his hand from the iron. Before the brain processes the events that have occurred. Nerve impulses carrying messages to the spinal cord and spinal send commands in the form of impulses to the muscles pull the hand away from the iron hand. 

B. Peripheral nervous system             Peripheral nervous system or peripheral nervous system plays with messages and information coming out of the central nervous system. Peripheral nervous system is divided into two namely: 1) somatic nervous system and 2) the autonomic nervous system. Somatic nervous system (skeletal nervous system) consists of the nerves associated with sensory receptors that make a person able to feel the world. Skeletal muscles also allows one to perform deliberate actions such as turning on the lights, feel the insect was walking on his body, somatic system is active. Autonomic nervous system function as a regulator of blood vessels, glands and internal organs such as bladder, stomach and heart. When someone is angry then his ears flushed or emotion until the heartbeat is increased, then that's where the autonomic nervous system is on. Autonomic nervous system is divided into two parts, namely the sympathetic nervous system and the parasympathetic nervous system, where each of the nervous system is working in the opposite order to the body can adapt to the environment. For example, the sympathetic nervous system makes a person's face became red, issued a drought and the energy issue, improve heart  rate and blood pressure, sympathetic nervous system works when a person is in a situation that demands for a fight, escape and overcome the condition. The workings of the parasympathetic nervous system does not actually stop the process in the body but tend decrease and keep everything running smoothly. For example, the parasympathetic nervous system causes the body to conserve and save energy, and when someone is fleeing from the pursuit of making the nervous system increases heart rate is slow again aan heart rate and keep the heart rhythm in order to stay regular.
