Cesarean Section

A Cesarean section is surgical procedure to bring a baby. The baby is taken out during the mother's abdomen. In the United States, concerning one in four women have their babies this way. Most C-sections are done when unforeseen problems happen during delivery. These include

* Health harms in the mother

* The point of the baby

* Not sufficient room for the baby to go through the vagina

* Signs of pain in the baby

C-sections are also more ordinary among women carrying more than one baby.

The surgery is fairly safe for mother and baby. Still, it is major surgery and carries risks. It also takes longer to get well from a C-section than from vaginal birth. After healing, the opening may leave a weak spot in the wall of the uterus. This could cause evils with an attempted vaginal birth later. However, more than half of women who have a C-section can give vaginal birth later on.

Music

Music is an art form that involves organized sounds and quiet. It is articulated in terms of pitch (which includes melody and harmony), rhythm (which includes tempo and meter), and the quality of sound (which includes timbre, articulation, dynamics, and texture).Music may also absorb generative forms in time through the construction of patterns and combinations of natural stimuli, principally sound. Music may be used for artistic or aesthetic, communicative, entertainment, traditional or religious purposes. The definition of what constitutes music varies according to culture and social context, with assorted interpretations of the term being established under sub-genres of the art. Within "the arts", music can be classified as a performing art, a fine art, or an auditory art form.

The history of music predates the written word and is tied to the enlargement of each unique human culture. The development of music among humans occurred against the backdrop of natural sounds such as birdsong and the sounds other animals use to communicate. primeval music, once more commonly called primitive music, is the name given to all music created in preliterate cultures (prehistory), beginning somewhere in very late geological history.
