Brain Cells Function

Speaking to your right foot will not make it stopover wiggling. Asking your left over(p) arm to bend and scratch your back will not make it dramatise either no matter how loudly a some one and only(a) asks. However, right feet do stop wiggling and left arms stool be made to scratch backs if one thinks and wants the limbs to stop or start moving. This is because mints movements be not voice-activated but rather are controlled by commands coming from a persons caput. The humor is the center or meeting place of the human nervous dodging. Kids Biology draw the nervous system as the main power cable of the body.Through it, the brain is able to receive and blame messages to all the other body parts. It drive out command the hand to per work certain movements while senses can tell the brain about the persons environment and its effects on the person, such as feelings of pain and heat. Basically, the nervous system is like a built-in telephone inside the body which the brain and the rest of the body can use to tell one another what the body should do or not do. According to Kids Biology, the messages sent are in the form of electricity, similar to the email or the internet, lonesome(prenominal) much, much faster.The things pushing along this electricity inside peoples bodies are called neurons. Brain cell Online explained that neurons are one of the two kinds of cells, the tiny human particles found in the brain. The other one is the glial cell. According to Brain Cell Online, thither are more than 100 billion neurons in the brain. However, there are much more glial cells as they account for 90 percent of the brains overall cell count. Glial cells act as the support for the neurons which, as mentioned above, are the cells responsible for walk on the messages between the brain and body in the nervous system.Neurons are not limited in the brain region alone rather, they are found throughout the nervous system. Brain Cell Online assign neurons with storin g and processing teaching from the brain before sending the information to the right receivers, and vice versa. To perform these octuple responsibilities successfully, neurons are equipped with two special projections or cell endings called dendrites and axons. Chudler distinguishes the two as such Dendrites subscribe or push nerve information to the cell body, while axons pull or take them away(predicate) and pass to another cell.Thus, neurons are like chains of information passing nerve information from one neuron to another until it reaches the brain or the designated body part. According to Chudler, the information being transferred is in the form of chemicals called neurotransmitters, which flow in and pass through neurons by small gaps called the synapse. The opening allows chemicals to move through electrons so as to make the connections for information chains possible. Chudler further explains that a synapse is composed of three parts a presynaptic end, a postsynaptic en d, and the synaptic cleft which is basically the middle part between the ends.Presynaptic ends are neurotransmitter terminals while postsynaptic ends are neurotransmitter receptor sites. An electrical impulse triggers the release of the neurotransmitters into the cleft until it finally reaches the postsynaptic end where they bind themselves with the receptor site. Chudler writes that this masking can alter cells excitability that is increasing or decreasing its potential to spark plug or intensify the cells actions and speed up the transmission of the messages or information being passed.Bain cells are manifestly important in peoples experience of the environment. As such, problems with the functions and capabilities of ones nervous system and all its components such as the neurons have turned into the most difficult and incurable diseases like Alzheimers syndrome, stroke, and epilepsy. Fortunately, there are studies evidencing the existence of the concept called neurogenesis. Ac cording to the Society of Neuroscience, neurogenesis refers to the human capability of producing new neurons which can integrate themselves to the working brain (1).This phenomenon suggests the exciting possibility of a self-healing brainone that keeps one from forgetting and treats brain disorders. Everyone is dependent on having a fully-functioning nervous system, from the brain to the senses and to the tiny microscopic neurons for their daily living. It may be difficult to imagine, but people are able to move their bodies and remember people, objects, and events through complex and lighting-fast information transfer inside our bodies tiny cells.
