According to Kalat (2000) the relationship between the brain and every other inch of the body is one that cannot be replaced by any other functions. The brain is however, not helpful without the billon neurons incorporated in the human body. The human body needs the neurons to communicate commands from the brain. In an argument by Kalat (2000) neurons are the most important body cells in the human body. From the brain neurons are connected to the rest of the body through the spinal cord. The spinal cord contains the largest composition of neurons that convey commands from the brain to the rest of the body (Open University Course Team, 2007). After commands have been formulated in the brain, the cells in the neurons convey the message through from the command system to the bottom of the brain. From the bottom part of the brain, the spinal cord is then brought in to the chain of communication. The spinal cord runs down the spine of the human body carrying with it billions of neurons which have in them command and communication from the brain. It is from this chain that every aspect of the human body is controlled: the movement of the limbs, the reaction to danger and the general stimulus in the body. Kalat (2000) argues that neurons hold the assurance of survival in all humans. Neurons are the main composition of the nervous system. In the nervous system, neurons are aided by the glial cells. The glial cells ensure the continuity of the neuronal activity which ensures the existence of neurons. Minus the glial cells neurons may die and the consequences may be fatal. The nervous system has a composition of 100 billion. However, neurons still exist in all other part of the body. A single neuron connects to 10, 000 other neurons. This feature enables s the speed of communication between the brain and body parts to take less than seconds. The speed of communication between two neurons is 330 miles per hour (Open University Course Team, 2007). With such a high speed the reaction of the human body part is as fast. For instance, it takes a person less than a second to detect the smell of food, interpret the type of food and know the direction the aroma is coming from. The author further argues that this example shows how fast and accurate the neurons are in transmitting information from the brain to the rest of the body. A single neuron is comprised of three parts. One is the cells body which contains the nucleus and it processes the information received from other neurons. There is the dendrite which receives information from other neurons. Then there is the axon whose main function is to convey information to other neurons. This neuron structure creates the fast and efficient nature of the cell. The functionality of the neurons depends on synapses. Synapses are functional communication or connections between neurons and another neuron or another body cell. One neuron generates thousands of synapses but this statistic varies with functionality. Synapses connect the axon to the dendrite. With the help of synapses neurons are enabled to make circuits through the nervous system and convey information to other cells. During a chemical synapse a neuron a neurotransmitter that is adjacent to another neuron. The human brain is estimated to have an approximated number of 500trillion synapses. This shows how dependent human brain is dependent on neurons. Human behavior is an integral part of the human body.
