Study Notes
The Human Ear
External Ear
- The pinna (auricle) collects sound waves and directs them into the external auditory meatus.
- The external auditory meatus is a narrow, S-shaped tube that reduces sound wave interference and helps to collect sound waves.
- The external auditory meatus contains wax-secreting glands and sebaceous glands, which help to protect the ear canal from dirt and infections.
Middle Ear
- The primary function of the middle ear is to transmit sound vibrations from the outer ear to the inner ear.
- The eustachian (auditory) tube connects the middle ear to the back of the throat, allowing for air pressure equalization.
- The bony ossicles (malleus, incus, and stapes) in the middle ear amplify sound vibrations and transmit them to the inner ear.
- The eardrum (tympanic membrane) separates the outer ear from the middle ear, and vibrates when sound waves reach it, transmitting these vibrations to the ossicles.
Sound Conduction
- Sound waves reach the internal ear through air conduction, where sound waves travel through the outer ear, causing the eardrum to vibrate, which then transmits these vibrations to the bony ossicles.
- Bone conduction plays a role in normal hearing, where sound vibrations can be transmitted directly to the inner ear through the bones of the skull, bypassing the outer and middle ear.
