Question

anyone explain the structure of human ear!!!!!!!!!! (no irrelevant answers and comments)........

Answer 1

The outer ear consists of the visible part of the ear or pinna, the external auditory canal (meatus), and the tympanic membrane (tympanum) or eardrum. The human pinna is formed primarily of cartilage and is attached to the head by muscles and ligaments. The deep central portion of the pinna is called the concha, which leads into the external auditory canal, which in turn leads to the tympanic membrane.

Answer 2

The outer ear is called the pinna and is made of ridged cartilage covered by skin. ... The spiral-shaped cochlea is part of the inner ear; it transforms sound into nerve impulses that travel to the brain. The fluid-filled semicircular canals (labyrinth) attach to the cochlea and nerves in the inner ear
