Sound waves enter the ear through the external auditory canal, which is the tube that runs from the outside of the head to the eardrum. The external auditory canal is about 3/4 of an inch wide and is curved to match the shape of the ear. The skin of the external auditory canal is thin and has few oil glands, so it is dry and can easily become infected.
The external auditory canal is lined with hair and wax. The hair traps dirt and dust and the wax helps to keep the ear canal moist. The wax is produced by the ceruminous glands, which are located in the external auditory canal. The wax is secreted by the glands and then it is moved to the surface of the skin by the hair.
The wax is important because it helps to protect the ear from infection. The wax traps bacteria and other debris and the enzymes in the wax help to break them down. The wax also helps to keep the ear canal moist, which prevents the skin from becoming dry and cracked.

Where do sound waves enter the ear quizlet?
There are three parts of the ear that are responsible for hearing: the outer ear, the middle ear, and the inner ear. The outer ear is made up of the ear canal and the earlobe. The ear canal is the tube that goes down into your ear, and the earlobe is the fleshy part of your ear that hangs off the side of your head. The middle ear is the small, air-filled chamber that is located behind your eardrum. The inner ear is the part of the ear that is responsible for hearing and balance. It is made up of the cochlea and the semicircular canals.
The sound waves enter your ear when they hit your eardrum. The eardrum is a thin piece of tissue that separates the outer ear from the middle ear. When the sound waves hit the eardrum, they cause it to vibrate. The vibrations then travel through the ear canal to the middle ear. The vibrations cause the eardrum to move back and forth, and this movement sends pressure waves through the air-filled middle ear. These pressure waves hit the cochlea and cause it to vibrate. The vibrations of the cochlea then send signals to the brain that allow you to hear the sound.
How are sound waves transmitted to the inner ear?
Sound waves are transmitted to the inner ear through the ear canal. The ear canal is a long, narrow tube that is about 1 inch long. The ear canal is curved and ends at the eardrum. The eardrum is a thin piece of tissue that separates the ear canal from the middle ear. The middle ear is a small, air-filled chamber that is located behind the eardrum. The middle ear contains the three small bones of the ear: the malleus, the incus, and the stapes.
The sound waves cause the eardrum to vibrate. The vibrations cause the three small bones of the ear to vibrate. The vibrations cause the cochlea to vibrate. The vibrations cause the hair cells in the cochlea to vibrate. The vibrations cause the auditory nerve to send a signal to the brain. The brain interprets the signal and we hear the sound.
How is sound processed in the ear quizlet?
How is sound processed in the ear quizlet?
The ear is divided into three parts: the outer ear, the middle ear, and the inner ear.
The outer ear is made up of the ear canal and the ear flap (pinna). The ear canal is a tube that goes from the ear flap to the eardrum. The ear flap is the part of the ear that you can see. It is hooked up to the muscles of the face so that it can move.
The middle ear is made up of the eardrum and the three tiny bones that are attached to it. The eardrum is a thin piece of skin that separates the outer ear from the middle ear. The three tiny bones are called the hammer, the anvil, and the stirrup. The hammer is attached to the eardrum. The anvil is attached to the hammer. The stirrup is attached to the anvil.
The inner ear is made up of the cochlea and the nerve that goes to the brain. The cochlea is a spiral-shaped tube. The nerve that goes to the brain is called the auditory nerve.
Sound travels from the outside of the ear to the eardrum. The eardrum vibrates when it is hit by sound. This vibration travels through the three tiny bones to the cochlea. The cochlea is filled with tiny hairs. When the vibration hits the tiny hairs, they move. This movement sends a message to the brain telling it what sound has been heard.
When sound waves enter the ear they cause the eardrum to quizlet?
When sound waves enter the ear they cause the eardrum to quizlet. The eardrum is a thin membrane that separates the ear canal from the middle ear. When sound waves hit the eardrum, it vibrates and causes the three small bones in the middle ear to vibrate. These bones transmit the vibrations to the cochlea, which is filled with liquid and contains thousands of tiny hair cells. The vibrations cause the hair cells to move, which sends a signal to the brain telling it what sound was heard.
What is the pathway of sound vibrations to the inner ear quizlet?
The pathway of sound vibrations to the inner ear quizlet is a complex process that begins with the vibration of the tympanic membrane. This membrane is located at the entrance of the ear canal and is responsible for transmitting sound vibrations to the middle and inner ear. The vibrations are then passed on to the cochlea, which is responsible for converting them into electrical signals that are sent to the brain.
How are sounds transmitted?
How are sounds transmitted?
The transmission of sound is a process that occurs when a sound wave is created and travels through the air, or any other medium, to be heard by someone or something. The sound wave is created by the vibration of something, and can be heard when it reaches the ear drum.
The transmission of sound can be affected by a number of factors, including the environment in which it is travelling, the weather, and the distance between the source of the sound and the person or object that is listening to it.
The environment in which the sound is travelling can affect the transmission of sound in a number of ways. For example, if the sound is travelling in a closed space, such as a room, it will be heard more clearly than if it is travelling in an open space, such as a field. This is because the sound is travelling in all directions in a closed space, whereas it is being spread out more in an open space.
The weather can also affect the transmission of sound. For example, if it is raining or windy, the sound will be harder to hear than if it is a calm day. This is because the weather conditions can affect the way that the sound wave travels.
The distance between the source of the sound and the person or object that is listening to it can also affect the transmission of sound. For example, if the person or object is far away from the source of the sound, it will be harder to hear than if they are close to it. This is because the sound wave will weaken as it travels through the air.
In which of the area of the brain are sound waves processed quizlet?
In which of the area of the brain are sound waves processed quizlet?
The answer to this question is still being researched, but scientists believe that the area of the brain responsible for processing sound waves is the temporal lobe. This part of the brain is located just above the ears, and it is responsible for interpreting the sounds that we hear.
