Where is the rumble-maker?

Cats hum is a real song forlovers of these pets. It is believed that such sounds the cat expresses its pleasure and other positive emotions. Meanwhile, so far, scientists are puzzling over the question - what are the cats purring and where is the rumor with which they reproduce these sounds?

What is the rumble-maker

It is considered that the rumble is athe vocal muscles of the larynx, as well as the vocal cords, which quickly shrink, and then, during breathing, relax. This produces a sound called rumbling. Many scientists used to think that this rumble is only found in domestic cats, but it does not occur in large animals of the cat family. This opinion was motivated by the fact that the hypoglossal bone involved in the process of sound formation contains cartilaginous tissues in large felines. Due to this they can make a loud roar or even a roar, while in other cats this bone is calcified completely and is a rigid structure.

Theories of the arrangement of the cat's lord

Among other theories explaining where the catsthere is a rumor, one version connects the occurrence of these sounds with the "Jakobson's organ". It is located near the cat in the sky, and is also used to recognize odors. However, it is still one of the theories, as well as the previous ones.

A curious explanation of where in catsis the theory of the American researcher Dr. Mildren Moealk, who for years has been observing and recording the sounds that hundreds of cats have published. From her research it follows that, just like humans, cats reproduce sounds by passing air from the lungs through two elastic vocal cords that are located in the larynx. That's only unlike people, a cat does not use the tip of the tongue, which shapes these sounds. Instead, the cat creates thirteen vowels, changing the muscle tension in the mouth, lips, throat and nasal sinuses.
