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.

20 lip 2024 · The external ear (or outer ear) comprises the auricle (or pinna), the external auditory meatus, and the tympanic membrane ("eardrum").

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).
The external ear consists of the expanded portion named the auricula or pinna, and the external acoustic meatus. The former projects from the side of the head and serves to collect the vibrations of the air by which sound is produced; the latter leads inward from the bottom of the auricula and conducts the vibrations to the tympanic cavity.
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 external ear consists of the auricle, which projects from the side of the head, and the external auditory meatus or ear canal, which passes inwards to the tympanic membrane. We'll look at the auricle first. The folded outer rim of the auricle is the helix.
