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.

Ear pits (preauricular pits) are often a rather subtle finding on physical exam. They are located at the superior attachment of the pinna to the face and may be unilateral or bilateral. Up to 10% of Asian infants will have pits -- they are less common among caucasians and African Americans.

2017年3月28日 · Surface Structures of the Auricle/Pinna. The major landmarks of the auricle/pinna are depicted in Figure 1. The auricle consists of skin (with adnexa), cartilage, and extrinsic and intrinsic muscles.

The anatomy of the external ear, also known as the auricle or pinna, is complex [Hunter and Yotsuyanagi, ] and remarkably inaccurately described by most authors. The major landmarks of the external ear are depicted in Figure 1.

The pinna is the visible portion that protrudes from the head and serves several functions. It helps collect sound waves from the environment and directs them toward the eardrum. Additionally, its unique shape aids in sound localization, allowing us to determine where sounds are coming from. The Anatomy of the Ear Pinna

2023年10月19日 · The curly and twirly part of the ear is the outer ear, called the pinna or auricle. The pinna is made of flexible, foldable cartilage and skin. The pinna has different parts: the tragus, the helix, and the lobule, while the interior has the hollow, cone-like concha.

2020年8月16日 · 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.

2025年1月22日 · The auricle (or pinna) is the visible part of the external ear, composed mainly of elastic cartilage covered by skin. Its intricate structure consists of various folds, ridges, and depressions that give it its unique shape.

2015年11月19日 · To prepare, you will create two or three types of pinnae. A pinna is the scientific name for the extension of the ear that sticks out from the side of the head. First, create a pair of...
