In the anatomy of humans and various other tetrapods, the eardrum, also called the tympanic membrane or myringa, is a thin, cone-shaped membrane that separates the external ear from the middle ear.

What do eardrums look like? Your eardrum is a thin, circular piece of tissue that measures about 1 centimeter in diameter (about one-third the size of a U.S. penny). A healthy eardrum is pearly white or gray in color, but you can see through it.

鼓膜 （英文：Tympanic membrane），又称 耳膜 （eardrum），是分割 外耳 和 中耳 的薄膜，将 耳道 和 鼓室 隔开 [1][2][3]。 鼓膜是 耳 的重要组成部分，它获取空气中的 声音，并将之传递给中耳中的 听小骨 [3]。 在听小骨中，直接与鼓膜相连的是 锤骨。 鼓膜的破裂或者 穿孔 会导致 传导性听力损失。 鼓膜形成于胚胎时期的 咽囊 （英语：pharyngeal pouch） 和 咽沟 （英语：pharyngeal groove）。 胚胎30天左右，在内胚层， 鼓室 首先形成，并将中耳的 听小骨 封闭 …

2024年5月8日 · Hearing loss and ear pain are common signs of an eardrum injury. This article describes the anatomy and function of the eardrum. It also looks at conditions that affect the eardrum, including how they are diagnosed and treated.

It plays a critical role in hearing by acting as a barrier between the outer ear and the middle ear. The eardrum is composed of three layers: an outer layer of skin, a middle layer of fibrous tissue, and an inner layer of mucous membrane. This structure allows it …

2025年1月16日 · tympanic membrane, thin layer of tissue in the human ear that receives sound vibrations from the outer air and transmits them to the auditory ossicles, which are tiny bones in the tympanic (middle-ear) cavity. It also serves as the lateral wall of the tympanic cavity, separating it from the external auditory canal.

2023年5月8日 · The tympanic membrane (eardrum, myringa) is a thin, semitransparent, oval membrane, approximately 1 cm in diameter, that separates the external acoustic meatus from the tympanic cavity. [1] [2] It is positioned at the lateral end of the external acoustic meatus and it is tilted medially from posteriorly to anteriorly and superiorly to inferiorly.

2023年10月30日 · The tympanic membrane (eardrum) is an oval, semi-transparent structure situated between the external auditory meatus and the tympanic cavity of the middle ear. The tympanic membrane is divided into two main parts: Pars tensa - …

Our eardrums are designed to pick up everything. The outer ear consists of the pinna and auditory canal, and the boundary between it and the middle ear is formed by the tympanic membrane, or eardrum. What is more, it releases a thousand times more energy into the eardrums.

The thin semitransparent tympanic membrane, or eardrum, which forms the boundary between the outer ear and the middle ear, is stretched obliquely across the end of the external canal. Its diameter is about 8–10 mm (about 0.3–0.4 inch), its shape that of a flattened cone with its apex directed inward. Thus, its outer surface is slightly concave.
