Nervous System and Distribution of the Healthy Body
To be able to support the limb to perform normal various activities, there are nervous system that has a method of division of labor in every part. Each cell has each task that must be executed properly.
Like a shoe manufacturer, there are employees who work as a designer, there is a charge of making the frame, there is a section giving the label, there are in the position of packing and so on. Between one part and another to be able to work well together so that it can have a positive impact on output.
Similarly, the nervous system that has multiple sections with each job description.
Between one cell to another cell must be well harmony that humans could eventually doing daily activities properly. It means the activities are smooth without any significant disruption. If there is one cell that is 'in disorder', and it would not carry out any ordes, the consequences could be fatal.
For example, our eyes can blink or close together, but because there are nerve cells that do not function properly causing the one eye close and another open. What will hapen to the whole body ?.
An unusual circumstances. Terrible, we could never sleep for rest. These conditions are for example the case in patients who suffered from Bells Palsy disease.
The nervous system is divided into five sections, namely:
1. Receptor cells, this is a nerve cell that plays as a receptionist or reception. Any information is always through this cell. It acts as a receptionist, these locate on the five senses, for example in the eye, ear, nose, and so on.
2. Effector cells, this is a nerve cell that is positioned in the second part after Receptor cells. These cells' function is in response to stimuli or stimulus received. Effector cells is composed of muscles and glands.
3. Sensory nerve cells, this is the part of the nervous system that served as a 'messenger' or stimuli that carry information to the brain.
4. Motor nerve cells, if the sensory nerve cells in charge of carrying information or stimuli to the brain, the motor nerve cells is in charge of taking or carrying stimuli or information from the brain.
5. Connector nerve cells, nerve cells that have this task combines one nerve cell to another nerve cell.
How it Works Nerves How nerve cells fulfill their duties? First of all external stimuli or stimulus received by the 'front' of nerve cells called receptors. Furthermore from recipient cells forwarded to sensory nerve cells.
Continuing journey of sensory nerve to the brain and previous stimuli through 'regional power' connector nerve cells. In this part of the brain that new information is processed in such a way to come including the translated until the answers to the information received earlier.
From the response to the information received by the end of this information is forwarded from the brain to the motor cells which ultimately translates this information in a particular movement. It is the occurrence of a movement that is planned or in the normal category.
What about the groove reflex? Reflex motion is motion that occurs suddenly. The emergence of the movement occurred within the span of a split second. On the motion that occurs suddenly, the stimulus or impulse that is not through a common pathway as the normal movement, but through a shortcut.
The plot of 'reception' receptor called earlier, then passed directly from sensory nerves to the central nervous system. This information is then received by a nerve connections or associations without first processing in the brain which in turn will forward it to the section called effectors such as muscles and glands are forwarded to a motor nerve.
Trip information does not take the usual common shortcut named this past Curved reflex. Spontaneous or reflex movements can be distinguished on the reflex spinal marrow and brain reflexes.
If the spinal marrow reflex occurs when nerve cells nerve connections in the spinal cord, for example in which there is a spontaneous movement on the knee. While the brain reflexively interpreted if nerve connections or associations in the brain. An example of this is the movement of the brain reflex blinking, eyes narrowed against the glare with existing light and so on.
Explains briefly how nerves work in a healthy body.
Hopefully these information be useful.
