Question

Explain the stucture of ear

Answer 1

Ans.
Structure Of Ears:-
The ear has external, middle, and inner portions. The outer ear is called the pinna and is made of ridged cartilage covered by skin. Sound funnels through the pinna into the external auditory canal, a short tube that ends at the eardrum (tympanic membrane).

The function of the outer ear is to collect sound waves and guide them to the tympanic membrane. The middle ear is a narrow air-filled cavity in the temporal bone. It is spanned by a chain of three tiny bones—the malleus(hammer), incus (anvil), and stapes (stirrup), collectively called the auditory ossicles.
