Ear - Wikipedia
An ear is the organ that enables hearing and (in mammals) body balance using the vestibular system. In mammals, the ear is usually described as having three parts: the outer ear, the middle ear and the inner ear. The outer ear consists of the pinna and the ear canal.
Ear (Anatomy): Overview, Parts and Functions - Biology Dictionary
Sep 7, 2017 · The tympanic membrane, or “ear drum” is a thin, tightly-stretched membrane that separates the outer from the middle ear. Just like the membrane of an actual drum, the tympanic membrane vibrates in response to the sounds that are funneled to it by the pinna and ear canal.
Eardrum - Wikipedia
In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear. Its function is to transmit sound from the air to the ossicles inside the middle ear, and thence to the oval window in the fluid-filled cochlea .
Explainer: How the ears work - Science News Explores
Oct 31, 2017 · In animals with an outer ear and ear canal, the ear drum — or tympanum — is inside the head. This tight membrane stretches across the end of the ear canal. As sound waves slam into this ear drum, they vibrate its membrane. …
Ear Structure and Function in Dogs - MSD Veterinary Manual
The average dog can hear about 4 times better than the average person, including sounds at higher frequencies than can be detected by the human ear. The middle ear includes the eardrum and a small, air-filled chamber that contains 3 tiny bones: the hammer, anvil, and stirrup.
36.4: Hearing and Vestibular Sensation - Biology LibreTexts
In mammals, sound waves are collected by the external, cartilaginous part of the ear called the pinna, then travel through the auditory canal and cause vibration of the thin diaphragm called the tympanum or ear drum, the innermost part of the outer ear (illustrated in Figure \(\PageIndex{2}\)).
Developmental aspects of the tympanic membrane: Shedding …
The ear drum, or tympanic membrane (TM), is a key component in the intricate relay that transmits air-borne sound to our fluid-filled inner ear. Despite early belief that the mammalian ear drum evolved as a transformation of a reptilian drum, newer fossil data suggests a parallel and independent evo ….
Major evolutionary transitions and innovations: the tympanic middle ear
Feb 2, 2017 · Developmental biology has played an important role in unmasking the different mechanisms by which the ear forms in mammals and sauropsids, highlighting the different possible ways to make an external ear canal, an ear drum, an air-filled space, a …
How Hearing Works - Ocean Conservation Research
Ear bones – Incus, stapes, malleus – transfers the motion of the ear drum to the cochlea. Cochlea – a stunning little organ that converts all of the signals from the vast surroundings into that neural impulses that animals use to create their “auditory scene.”
