What is the pathway of sound waves through the ear?

ear canal
Sound waves enter the outer ear and travel through a narrow passageway called the ear canal, which leads to the eardrum. The eardrum vibrates from the incoming sound waves and sends these vibrations to three tiny bones in the middle ear. These bones are called the malleus, incus, and stapes.

What are the four steps for the pathway of sound waves?

The Steps of Hearing

• Outer Ear. Sound waves, which are vibrations, enter through the outer ear and reach the middle ear to vibrate the eardrum.
• Middle Ear. The eardrum then vibrates the ossicles, which are small bones in the middle ear.
• Inner Ear.
• Auditory Nerve.

Which is the correct order for sound traveling to the inner ear?

The vibrations are transmitted further into the ear via three bones (ossicles): malleus (hammer), incus (anvil), and the stapes (stirrup). These three bones form a bridge from the tympanic membrane to the oval window. 5. Once sound passes through the oval window, it enters into the cochlea in the inner ear.

What is the correct pathway for sound to the brain?

Auditory messages are conveyed to the brain via two types of pathway: the primary auditory pathway which exclusively carries messages from the cochlea, and the non-primary pathway (also called the reticular sensory pathway) which carries all types of sensory messages.

What is the path of sound through the ear?

Cilia are sensory organs, and the longest cilia have tectorial membranes at the top, which move back and forth with sound cycles. Sound travels as a wave through the outer and middle ear before transforming into an electrical impulse. The first area of the brain that receives auditory input is the primary auditory cortex.

How are sound waves related to the tympanic membrane?

As mentioned above, the vibration of the tympanic membrane is what triggers the sequence of events that lead to our perception of sound. Sound waves travel into our ears at various speeds and amplitudes. Like light waves, the physical properties of sound waves are associated with various aspects of our perception of sound.

Which is part of the ear vibrates when sound waves hit it?

When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles.

Where does hearing start in the human ear?

Hearing starts with the outer ear. When a sound is made outside the outer ear, the sound waves, or vibrations, travel down the external auditory canal and strike the eardrum (tympanic membrane). The eardrum vibrates. The vibrations are then passed to 3 tiny bones in the middle ear called the ossicles. The ossicles amplify the sound.
