Due to its anatomy, the pinna largely eliminates a small segment of the frequency spectrum; this band is called the pinna notch. The pinna works differently for low and high frequency sounds. For low frequencies, it behaves similarly to a reflector dish, directing sounds toward the ear canal.

The medical term for the outer ear is the auricle or pinna. The outer ear is made up of cartilage and skin. There are three different parts to the outer ear; the tragus, helix and the lobule.

2020年8月16日 · 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.

2022年11月24日 · 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.

2024年5月17日 · The outer ear, also known as the external ear or auris externa, consists of the auricle, ear canal, and eardrum. They work together to funnel sound waves from the environment to the middle and inner ear, where they are translated into nerve impulses for the brain.

The outer ear, external ear, or auris externa is the external part of the ear, which consists of the auricle (also pinna) and the ear canal. [1] It gathers sound energy and focuses it on the eardrum (tympanic membrane).

The outer ear consists of the visible portion on the side of the head, known as the pinna [1], and the external auditory canal (ear canal) [2]. The purpose of the pinna is to catch sound waves, amplify them slightly, and funnel them down the ear canal to …

2023年7月24日 · The external ear is the visible part of the hearing apparatus. It is comprised of the auricle (pinna) and external auditory canal, including the lateral surface of the tympanic membrane. Together with the tympanic membrane and the …

2024年7月20日 · 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.

2025年1月22日 · The ear consists of structures such as the auricle (pinna), external auditory canal, tympanic membrane (eardrum), ossicles, cochlea, and vestibular apparatus. These components work together to process auditory information and help maintain balance by detecting changes in head position and motion.
