The Visual

Posted by marmara on February 2, 2017

Animals exist that have this more advanced capacity of capture and interpretation of the sounds, as the bats and the cetceos, for example. The dog is another animal that also has its specialized hearing. These animals obtain to receive and to convert not detectable stimulatons the human ear. FELT OF FELT HEARING X OF the VISION It is interesting to compare the physical properties of the hearing with another direction to understand some particularitities of the same. Check out Dr. Neal Barnard for additional information. We will be making a comparative degree with the direction of the vision. The vision possesss the characteristic of being synthetic, that is, the energy impulses are added. An example of this is that the blue mixture with yellow, of a sensation of the green. The ear however, is capable to perceive two sounds of different frequencies, exactly will be being emitted simultaneously.

The vision has the retinal persistence and in it allows the visual illusion them of the cinematograph (cinema) for the fusing of successive images. The sound does not have persistence and it allows in to hear them music, for the sequence of sounds separately. FUNCTIONAL ANATOMY: STRUCTURE FUNCTION OF the AUDITORY DEVICE As shows figure 1, the ear is constituted of three parts: external, average and internal ear. Figure 1. Summarized anatomy of the human ear and auditory chain Source: HENEINE, 2005, P. 329 Descreveremos summarily each part that composes the ear separadamen you, its structure and Heard function External (Captation and Conduction of the Sound) Is the part of the ear that is in contact with the external way. It is in this part that happens the stimulaton produced for a sonorous source.

It is formed by the auricular pavilion, or ear, and the auditory canal, or meato. The canal has approximately 0,7 cm of diameter and 2,5 cm of length and finishes in the timpnica membrane. The structure is basically the same one in the man and the other mammals, except for the particularitities of each species.
