Ear Anatomy Diagram -- The ear has exterior, center, and inner sections. The external ear is known as the pinna and is created of ridged fibrous protected by epidermis. Audio funnels through the pinna into the exterior hearing tunel, a brief pipe that finishes at the eardrum (tympanic membrane).
Sound causes the eardrum and its small connected bone fragments in the center aspect of the ear to shake, and the oscillations are performed to the encompassing cochlea. The spiral-shaped cochlea is aspect of the inner ear; it converts sound into sensors desires that journey to the mind.
The fluid-filled semicircular pathways (labyrinth) affix to the cochlea and sensors fibres in the inner ear. They deliver details on stability and go place to the mind. The eustachian (auditory) pipe empties liquid from the center ear into the neck (pharynx) behind the nasal area.
Audio is gathered by the pinna (the noticeable aspect of the ear) and instructed through the external ears. The sound creates the eardrum shake, which will causes a sequence of three small bone fragments (the sort, the anvil, and the stirrup) in the center ear to shake. The vibrations is moved to the snail-shaped cochlea in the inner ear; the cochlea is covered with delicate hair which induce the creation of sensors alerts that are sent to the mind. On regular, human can listen to appears to be in the wavelengths between 20 to 20,000 Hertz.

Definitions:
anvil (also known as the incus) : a small cuboid that goes oscillations from the sort to the stirrup.
cochlea : a spiral-shaped, fluid-filled inner ear structure; it is covered with cilia (tiny hairs) that shift when vibrated and cause a sensors reaction to type.
eardrum : (also known as the tympanic membrane) a slim tissue layer that vibrates when audio surf achieve it.
Eustachian tube : a pipe that joins the center ear to the returning of the nose; it equalizes the stress between the center ear and the air outside. When you "pop" your hearing as you modify elevation (going up a hill or in an airplane), you are equalizing the air stress in your center ear.
hammer : (also known as the malleus) a small cuboid that goes oscillations from the eardrum to the anvil.
nerves fibre : these bring electro-chemical alerts from the inner ear (the cochlea) to the mind.
outer ears canals - the pipe through which audio moves to the eardrum.
pinna : (also known as the auricle) the noticeable aspect of the external ear. It gathers audio and guides it into the external ear canal
semicircular canals : three circles of fluid-filled pipes that are connected to the cochlea in the inner ear. They help us sustain our feeling of stability.
stirrup : (also known as the stapes) a small, U-shaped cuboid that goes oscillations from the stirrup to the cochlea. This is the tiniest cuboid in the human body (it is 0.25 to 0.33 cm long).
