How is the ear divided into three parts?
The ear is divided into three parts: Outer ear: The outer ear includes an ear canal that is is lined with hairs and glands that secrete wax. Middle ear: Three tiny bones — the malleus, incus, and stapes — within the middle ear transfer sound vibrations from the eardrum to the inner ear.
Which is part of the ear collects sound?
The human ear parts are explained below: The external ear is further divided into the following parts: The auricle comprises a thin plate of elastic cartilage covered by a layer of skin. It consists of funnel-like curves that collect sound waves and transmits them to the middle ear.
What is the function of the ear canal?
The ear canal functions as an entryway for sound waves, which get propelled toward the tympanic membrane, known as the eardrum.
How are the bones in the middle ear connected?
Human Ear Diagram. Auditory Ossicles: The three small bones in the middle ear, called malleus, stapes, and incus, are connected. These bones together are called the auditory ossicles, and their purpose is to let the sound that strikes the eardrum, further into the inner ear.
Is the Eustachian tube in the middle ear?
Eustachian Tube is a tube that connects the middle ear to the back of the nose. It helps to maintain equal pressure in the middle ear which facilitates the proper transmission of sound waves. Cochlea that comprises the nerves of hearing. Semicircular canals that contain the receptors that help in maintaining balance.
Which is the outer rim of the ear?
Helix: It is the prominent outer rim of the external ear. Antihelix: It is the cartilage curve that is situated parallel to the helix. Crus of the Helix: It is the landmark of the outer ear, situated right above the pointy protrusion known as the tragus.
auricle (cartilage covered by skin placed on opposite sides of the head) auditory canal (also called the ear canal) eardrum outer layer (also called the tympanic membrane) The outer part of the ear collects sound. Sound travels through the auricle and the auditory canal, a short tube that ends at the eardrum.
