The middle ear is the portion of the ear medial to the eardrum, and distal to the oval window of the cochlea (of the inner ear). The mammalian middle ear contains three ossicles (malleus, incus, and stapes), which transfer the vibrations of the eardrum into waves in …

2023年10月30日 · The middle ear is an air-filled pressurized space within the petrous portion of the temporal bone, extending from the tympanic membrane (eardrum) to the lateral wall of the internal ear. It is lined by mucous membrane and communicates with the nasopharynx anteriorly via the pharyngotympanic (Eustachian) tube and the mastoid antrum and air cells ...

2023年8月16日 · Middle ear anatomy can be broken down into different parts: the tympanic membrane, the tympanic cavity, the ossicles, and the auditory (eustachian) tube. Each has its own function and they all work together to help you hear. The tympanic membrane is also called the eardrum. It separates the middle ear from the external ear.

中耳 （英文：Middle ear）是 耳 的一个解剖结构，在层次上位于 外耳 和 内耳 之间 [1]。 中耳的主要结构是 鼓膜 （亦称“耳膜”）、 鼓室 和三个 听小骨 （构成听骨链） [1]。 鼓膜和听骨链形成一个力学系统，其功能是将来自外耳的声波的 力 放大，并输入到内耳，为下一步的听觉转导做准备 [2]。 中耳通过鼓室下部的 耳咽管 和 咽喉 相通。 鼓膜 是一个圆锥形的膜形结构，其后是空心的 鼓室 [1][3]。 鼓膜一面与 耳道 相连，另一面与 锤骨 相连；锤骨与 砧骨 相连，而砧骨的另一段 …

2025年1月21日 · The middle ear is an air-filled cavity within the temporal bone that contains the three small bones, or ossicles: the malleus, incus, and stapes. These ossicles are essential for transmitting sound vibrations from the outer ear to the inner ear. The middle ear is also connected to the back of the throat via the Eustachian

2022年12月22日 · The main function of the middle ear is to transmit vibrations from the tympanic membrane to the inner ear via the auditory ossicles. This article will focus on the anatomy of the middle ear – its structure, neurovasculature, and its clinical correlations.

The basic function of the middle ear is to transmit vibrations from the tympanic membrane to the inner ear. The middle ear is traditionally divided into three parts: the epitympanum (upper compartment), the mesotympanum (middle compartment) and …

The middle ear consists of the eardrum (tympanic membrane) and an air-filled chamber containing a chain of three bones (ossicles) that connect the eardrum to the inner ear (see Middle Ear). The middle ear amplifies sound, whereas the inner ear changes mechanical sound waves into an electrical signal that is sent to the brain via the nerve of ...

The middle ear is an air-filled cavity lined by a mucous membrane and occupied by the three middle ear bones (ossicles)—the malleus (hammer), incus (anvil), and stapes (stirrup) (Fig. 7.21).

The middle ear is the part of the ear between the tympanic membrane (separating it from the external ear) and the oval window of the inner ear. The tympanic cavity of the middle ear houses three tiny bones, the auditory ossicles, which transfer the vibrations of the tympanic membrane into the waves in the fluid and membranes of the inner ear.
