Labeled ear game online - Biology diagram

 

 

Our ears enable us to pick up sounds from our surroundings, listen and reply to other people, and enjoy music. The structure of the ears is primarily adapted to clearly pick up sound, although it also contains the vestibular system that provides our sense of balance.
The external part of the ear that we can see is called the pinna or auricle. It is made of cartilage and skin. Sound is collected by the pinna and funnelled into the outer ear canal. The sound makes the tympanic membrane (eardrum) vibrate.
These vibrations, in turn, are picked up and amplified by three tiny bones (ossicles) called the malleus, incus and stapes, in the middle ear. To ensure that the sound quality is clear, the Eustachian tube balances the air pressure in the middle ear.
Sound waves entering the inner ear pass through the cochlea, which looks like a snail shell. Nerve endings in the cochlea convert these vibrations into electrical impulses that are carried by the auditory nerve into the brain, which processes it into hearing.

This labeled ear diagram is a detailed and easy-to-read illustration to assist learners in familiarizing the structure of the ear, including the parts which are found inside the head. This diagram can also be helpful in understanding how the sense of hearing works properly.

Anatomy and Physiology of the Ear

The ear is a complex organ that is responsible for hearing and maintaining balance. It is made up of three main parts: the outer ear, the middle ear, and the inner ear.

The outer ear is made up of the pinna (the visible part of the ear) and the ear canal. The pinna collects sound waves and directs them into the ear canal, which leads to the eardrum.

The middle ear is a small, air-filled chamber that contains three small bones called the ossicles: the malleus, incus, and stapes. These bones amplify the sound waves and transmit them to the inner ear. The middle ear also contains the Eustachian tube, which equalizes the pressure between the middle ear and the outside environment.

The inner ear is a complex structure that contains the organ of hearing (the cochlea) and the organ of balance (the vestibular system). The cochlea is a snail-shaped structure that contains hair cells and fluids that convert sound waves into electrical signals that can be interpreted by the brain. The vestibular system is made up of the vestibule, the semicircular canals, and the saccule and utricle. These structures contain sensors that detect the position and movement of the head and send this information to the brain.
