Question

Give the technical names of the auditory ossicles in their natural sequence.

Answer 1

The ears perform two sensory functions, i.e. hearing and maintenance of body balance. Anatomically, the ear can be divided into three major sections namely; the outer ear, middle ear, and inner ear. The middle ear consists of three delicate bones which are referred to as the auditory ossicles.

Complete answer:
We already said the three major sections of the ear are the outer ear, the middle ear, and the inner ear. The outer ear consists of the pinna and the external auditory meatus. Pinna collects the vibrations from the air which produces the sound. The middle ear consists of three delicate bones called ossicles namely; malleus, incus, and stapes. These are attached to one another in a chain-like fashion, one after the other. The malleus bone is hammer-shaped. The incus bone is anvil-shaped. The stapes bone is stirrup-shaped. The ear ossicles increase the force of the vibration.

Additional Information:
-The auditory system regulates how we hear and understand sounds within the environment.
-Usually, the middle ear transmits the sound waves to the cochlear fluid present in the inner ear or cochlea. The cochlea then amplifies these sound vibrations in the cochlear fluid with the help of the organ of Corti.
-The auditory nerve receives the signal from the sense cells and works on it. It is made up of both external structures like the outer, middle, and inner ear and brain regions like cochlear nuclei, superior olivary nuclei, lateral lemniscus, inferior colliculus, medial geniculate nuclei, and auditory cortex.

Note:
-Sound waves reach the outer ear and travel down the external acoustic meatus to reach the eardrum.
-The Contact between the eardrum and environmental pressure waves causes movement of the membrane.
-Movement of the tympanic membrane brings about the vibration of 3 small bones within the middle ear: the malleus, incus, and stapes which transfer the vibration to the inner ear.
