What is diaphragm?

What Does diaphragm Mean

The Latin word diaphragma came to Latin as diaphragma , which in turn, in our language , derived in diaphragm . The concept has different meanings according to the context.

Diaphragm is a membrane composed of muscle fibers that is responsible for separating the abdominal cavity from the thoracic cavity. This tissue is present in the body of all mammals.
The diaphragm is involved in breathing , both in inhalation and exhalation. As you inhale, the diaphragm contracts, which helps increase the space that is available in the chest cavity and allows air to enter the lungs. On the other hand, when you exhale, the diaphragm relaxes and the air is expelled.

Lyrical singing teachers teach their students to "control" the movement of the diaphragm to make the most of the air. Lyrical singers, who deal with repertoires such as chamber music or opera, face considerable challenges on a vocal and respiratory level, far greater than those usually found in a popular song. For example, long lines are common in which you "should not" interrupt to breathe in, and this requires optimizing the breathing process.
The objective of this supposed control over the diaphragm, since in reality we cannot exactly decide its behavior but to delay its relaxation, is to prevent the air from escaping from the lungs when the body asks for it naturally, to make the most of it.
The technique that lyrical singers apply is very difficult to learn, mainly because they cannot see what is happening inside the body at all times. Broadly speaking, it consists of breathing with the lower part of the lungs and doing certain abdominal movements to "hold" the diaphragm in its extended position and prevent it from relaxing naturally.
Other physiological activities, such as the excretion of urine and feces or the action of vomiting, are also developed with the participation of the diaphragm.
In the field of optics and photography , a diaphragm is an element that gives the lens the ability to manage the amount of light entering a camera. The aperture of the diaphragm can therefore be adjusted so that the photosensitive medium receives more or less light.
Another use of the notion of the diaphragm is used in contraception . It is a method created at the end of the 19th century , which consists of a flexible disk that is located in the cervix to prevent the entry of sperm.

A spermicide is added to the diaphragms to increase their effectiveness. It is important to note that this device does not provide protection against sexually transmitted diseases. It also increases the risk of having a urinary infection.
The first step to taking advantage of the diaphragm is to use it in every sexual relationship: just skip once to throw away all the effort. This is essential from a statistical point of view, since the chances of pregnancy without any protection are much higher. But it is also necessary to take other precautions, such as placing it before arousal begins and making sure that the man ejaculates out of the vagina.
It is said that when used correctly its effectiveness can reach 94%, while the most common errors in its application reduce this value to 88%. In other words, we could say that twelve out of every hundred women who use this contraceptive method do not take advantage of it (either because they do not follow the instructions carefully or because they do not use it with each intercourse) and, therefore, they can become pregnant.
