4 lut 2022 · The external ear (EE) is anatomically and functionally divided into the cartilaginous auricle, or pinna, and the external auditory canal (EAC). The auricle captures, concentrates, and amplifies sound waves, directing them into the EAC.
16 sie 2020 · This article will focus on the anatomy of the external ear – its structure, neurovascular supply and clinical correlations. The external ear can be divided functionally and structurally into two parts; the auricle (or pinna), and the external acoustic meatus – which ends at the tympanic membrane.
7 sty 2021 · The pinna or auricle directs sound waves into the external auditory Meatus (EAM), which then funnels sound waves toward the ear drum or tympanic membrane (TM), causing it to displace and move the ossicular chain of bones in the air-filled middle ear.
The human external ear consists of the auricle (or pinna) and the external auditory canal. The function of the auricle is to collect sound waves and direct the acoustic energy down the external auditory canal toward the tympanic membrane (eardrum).
24 lip 2023 · Together with the tympanic membrane and the middle ear, the pinna serves to amplify sound. The pinna acts as a funnel to deliver sound to the external acoustic meatus, and the external auditory canal concentrates sound onto the tympanic membrane for further transmission.
20 lip 2024 · The external ear (or outer ear) comprises the auricle (or pinna), the external auditory meatus, and the tympanic membrane ("eardrum"). The auricle concentrates and amplifies sound waves and funnels them through the outer acoustic pore into the external auditory meatus to the tympanic membrane.
1 sty 2022 · The delicate yet definitive deflections of the auricle (pinna) of the external ear contribute to the collection of sound. The external acoustic meatus is responsible for the transmission of sounds to the tympanic membrane, which in turn separates the external ear from the middle ear.
