external auditory canal, passageway that leads from the outside of the head to the tympanic membrane, or eardrum membrane, of each ear. The structure of the external auditory canal is the same in all mammals.
23 wrz 2024 · The external acoustic meatus, also known as the ear canal, is a tubular passageway that extends from the outer ear to the tympanic membrane (eardrum). It is approximately 2.5 cm in length and is responsible for guiding sound waves from the external environment toward the middle ear.
28 wrz 2024 · The external ear refers to the outermost part of the ear, which is responsible for collecting sound and directing it into the auditory system. It is made up of two primary components: the auricle (or pinna) and the external auditory canal (also known as the ear canal).
3 lis 2023 · At the external ear, sound waves captured by the auricle enter the external acoustic meatus, and travel through it to the tympanic membrane. Under the strike of the wave, the membrane moves medially, affecting the handle of the malleus attached to the medial surface of the tympanic membrane.
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear. The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
