The nerve, and it leads to its transmission to the brain, which is interested in its interpretation.

The human eye is characterized by the ability to see in dim light at 910 degrees. The human eye sends its data to the brain through 10 billion nerve networks, all of which form a special processor of eye data.

The sense of hearing:

Every person has ears on both sides of the head and the components of the ear are connected to the skull and the human ear has three main parts:

Outer ear

It consists of two sections, the paana and the auditory canal, which represent the opening of the ear which man sees with his own eyes. This is the way of the eardrum. Hair covers the outer skin of the ear and its inner glands. Emits a yellowish substance called resin-type earwax. This gives the drum the necessary protection from the dirt trapped in it.

Middle ear

Includes hearing ability. Who communicate with each other.

Inner ear
