La mitosis es el proceso de división celular, caracterizado por la duplicación de todos los componentes celulares y la distribución uniforme de estos elementos en las células hijas.
En el proceso, una célula original 2n, da lugar a dos células hijas también 2n. Son células idénticas entre sí e idénticas a la original, conservando el mismo número de cromosomas.
La mitosis garantiza la reproducción de los organismos unicelulares y el crecimiento por aumento del número de células de los organismos pluricelulares. Actúa también en la renovación de tejidos y en la regeneración.
Es decir, la mitosis es un proceso de multiplicación de la célula que se caracteriza por una duplicación cromosómica y una división celular. El resultado es que las células hijas poseerán el mismo número de cromosomas que la célula madre.
Así, la mitosis es un mecanismo por el cual las células dan origen a otras. Esas células originadas son jóvenes y no sufrirán lesión por estrés de actividades biológicas. De esa forma, consiguen practicar la actividad biológica con mucha más facilidad, eficiencia y con menos errores que las antiguas células.
La característica principal de la mitosis es que, tanto las células hijas como la célula madre poseen la misma carga genética, como ya fue dicho, es decir, el mismo ADN. Además, la mitosis ayudará en otras funciones como:
- Crecimiento corporal, debido a la multiplicación de las células.
- Reemplazo de las células viejas, para la renovación de los tejidos.
- Regeneraciones a fin de auxiliar en la tarea del tratamiento de lesiones, necrosis y otros.
If you have difficulty sleeping, it may be a symptom of sleep apnea. Lots of people deal with this condition every day, and it is often a problem that is quite unpleasant to manage. But the good news is that there are effective treatments out there. Read this article to learn some basic information about recognizing and treating sleep apnea.
If you suffer from sleep apnea, you should use a Continuous Positive Airway Pressure machine while sleeping. This will help you treat your sleep apnea and get you on the path to having a full nights sleep. This machine uses either a face or nasal mask to pump air while you sleep.
If you are over weight, going on a diet can reduce your sleep apnea, or in rare cases, eliminate it completely. Maintaining a healthy weight can help you breathe easier, so losing weight and maintaining a healthy weight when you have trouble breathing is an obvious step in treating your sleep apnea.
If you have sleep apnea and cannot break the habit of sleeping on your back, try sleeping in a t-shirt with two tennis balls sewn into the back. Making this sleep shirt is a simple project to do at home, and it can help to break you of sleeping on your back. Every time you try to roll over on your back in your sleep, the tennis balls will remind you to roll back onto your side.
Understand the effects that smoking and drinking alcohol have on sleep apnea, if you are trying to get a grip on your quality of sleep. Smoking enlarges airways, while alcohol can relax them too much, both of which will contribute to the symptoms of sleep apnea severely. Consider making the necessary cut-backs that will cut down on your sleep problems.
If you think that you may have sleep apnea, set up a video of yourself as you sleep. Just be sure that the video recorder has sound capability. When you wake up, look at the video, and if it seems like something other than snoring is going on, it may be time to go to the doctor.
Sleep apnea does not go away on its own; patients need treatment. Some treatments work better for different people. If you lose weight you will help your sleep apnea, but this is not always the cause. CPAP machines are considered non-invasive, and many people use them successfully. Others prefer surgery to relieve their sleep apnea. Choose whichever method you think will work for you so you may begin to live a happy and comfortable life.
Avoid any type of drugs or alcohol if you are experiencing any type of sleep apnea. Drugs and alcohol will slow down your respiratory system, and that is known to be one of the causes of sleep apnea. If you are struggling with this issue, try to get some professional help to overcome these addictions.
If simple changes in your lifestyle, such as regular sleep hours and losing weight, have not eliminated your sleep apnea episodes, it is time to consult with a sleep specialist. The specific causes of your sleep apnea can be evaluated, and an individual treatment plan can be designed for you.
Sleep apnea can cause many problems beyond just the inability to get a good night’s sleep. If you let your condition go untreated, it may get worse over time. Getting enough sleep is crucial to your overall level of health, so start using the tips you have read in this article right away to find relief.
