23 lut 2017 · The position of the ear is advantageous for assessing vital status and detecting diseases through reliable and comfortable sensing devices.
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.
The first part of the external ear is the pinna or auricle. This is formed of irregular-shaped cartilage covered by firmly adherent skin. The dependent lobule is mainly fat. Anteriorly the cartilage forms the tragus, which covers the entrance of the external auditory meatus. The main anatomical features of the pinna are shown in Figure 2.2.
1 sty 2022 · Tragus—the cartilaginous (often hairy) prominence that partly overlaps the meatus. Antitragus— tubercle on the lower antihelix, opposing the tragus. Intertragic notch— separates the tragus from the antitragus.
The ear starts to develop as early as in the sixth week of pregnancy. During foetal development, the pinna (the visible part of the ear) forms from little bumps (hillocks) on the side of the head, which grow and fuse. Sometimes the pinna fails to develop fully – known as microtia – and in some babies the ear canal may also be absent.
24 lis 2022 · There is a cartilaginous portion, known as the pinna or auricle and a bony, tubular segment called the external acoustic meatus. The former portion of the auditory system is the first point at which sound wave modification begins.
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.
