24 lis 2022 · The tragicus muscle lies vertically on the lateral aspect of the tragus. It is a flat, short muscle that is perpendicular to (but not in contact with) the antitragicus muscle. Antitragicus originates from the anteroinferior part of the antitragus to the tail of the antihelix and helix.
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.
1 dzień temu · The external ear consists of the auricle (pinna) and the external auditory canal. Its primary role is to collect and direct sound waves into the ear. Auricle (Pinna): The visible part of the ear, made of elastic cartilage and skin. It has several landmarks including the helix, antihelix, tragus, and lobule, which help to funnel sound waves into ...
3 lis 2023 · Intrinsic muscles contribute to defining the shape of the auricle by passing between its cartilaginous parts. They are: helicis major, helicis minor, tragus, pyramidal muscle of auricle, antitragus muscle, transverse muscle of auricle, and oblique muscle of auricle.
28 wrz 2024 · Tragus: The tragus is a small, pointed flap of cartilage that projects outward from the front of the auricle, covering part of the external auditory canal. It is positioned anterior to the concha and plays a role in sound wave entry.
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.
The tragicus is a short, flattened vertical band on the lateral surface of the tragus. Also known as the mini lobe. The antitragicus arises from the outer part of the antitragus, and is inserted into the cauda helicis and antihelix. The transverse muscle is placed on the cranial surface of the pinna.
