Supports the external ear?
The external ear is supported by the elastic cartilage of the auricle (pinna). This cartilage helps maintain the shape and structure of the external ear, allowing it to collect and direct sound waves into the ear canal towards the eardrum. The external ear also contains the earlobe, which is primarily composed of fat and connective tissue.
What supports the external ear?
The external ear is supported by elastic cartilage, particularly the auricle (pinna) which is the visible part of the external ear. This cartilage provides structure and shape to the ear while allowing for flexibility and movement.
Where does the External ear end?
The external ear ends at the ear canal, also known as the external acoustic meatus, which extends from the outer ear to the eardrum.
What type of connective tissue make up the external ear?
The type of tissue that makes up your ears and nose is cartilage. I don't really know if you would consider that "connective tissue".cartilageCartilagecartlidgecartilagecartilageCartilage. cartilage
What is the external feature of ear that contains the helix and lobule?
The external feature of the ear that contains the helix and lobule is the pinna, also known as the auricle. The pinna is the visible part of the ear that collects sound waves and directs them into the ear canal.
Does a crane have ears?
Yes, but they have no external ear structure.
How is the external ear different from the outer ear?
The external ear refers to the entire structure outside the ear canal, including the auricle (pinna) and ear canal, while the outer ear specifically refers to the visible part of the external ear, which is the auricle.
True or False The structure that allows equalization of the pressure in the middle ear with that outside the body is the external auditory meatus?
False. The structure responsible for equalizing pressure in the middle ear with the outside is the Eustachian tube, not the external auditory meatus. The external auditory meatus is the passage that leads sound waves from the external ear to the middle ear.
Is there a difference between external auditory meatus and external acoustic meatus?
The external auditory meatus and the external acoustic meatus are two names for the same structure.
Supports the external ear?
The external ear is supported by the elastic cartilage of the auricle (pinna). This cartilage helps maintain the shape and structure of the external ear, allowing it to collect and direct sound waves into the ear canal towards the eardrum. The external ear also contains the earlobe, which is primarily composed of fat and connective tissue.
How does the structure and function of the external ear of a human relate to the structure and function of the external ear of a rabbit?
Both the external ears of humans and rabbits serve to collect and amplify sound waves to the middle ear. Their structures include the pinna (ear flap) and ear canal. However, rabbits' ears are larger and more mobile, enabling them to better detect predators and prey through sound localization.
What supports the external ear?
The external ear is supported by elastic cartilage, particularly the auricle (pinna) which is the visible part of the external ear. This cartilage provides structure and shape to the ear while allowing for flexibility and movement.
Which structure divides the external ear from the middle ear and can be visualized during otoscopy?
The structure that divides the external ear from the middle ear is the tympanic membrane, commonly known as the eardrum. It can be visualized during otoscopy as a thin, translucent membrane that vibrates in response to sound waves. The tympanic membrane plays a crucial role in hearing by converting sound waves into mechanical vibrations that are transmitted to the middle ear.
Which is a structure in the middle ear that can be partially visualized during otoscopy?
The tympanic membrane, also known as the eardrum, is a structure in the middle ear that can be partially visualized during otoscopy. It separates the external ear canal from the middle ear cavity and is an essential component for hearing.
How does the external ear work?
The external ear acts as a funnel to collect sound waves and direct them towards the middle ear. The shape and structure of the external ear help to amplify and localize sounds, while also providing protection for the delicate structures of the middle and inner ear. Sound waves enter the ear canal, causing the eardrum to vibrate and transmit these vibrations to the middle ear ossicles, which then amplify and transmit the sound further into the inner ear for processing.
What is the medical term meaning absence of the external ear?
The medical term for absence of the external ear is "anotia." This condition involves complete absence of the external ear.
Where does the External ear end?
The external ear ends at the ear canal, also known as the external acoustic meatus, which extends from the outer ear to the eardrum.
