耳蜗 （英語： cochlea）是 内耳 的一个解剖结构，它和 前庭系统 一起组成内耳 骨迷路，即内耳的核心结构 [1][2][3]。 耳蜗的名称来源于其形状与 蜗牛 壳的相似性，英语 cochlea，即 拉丁语 “蜗牛壳”之义。 耳蜗是 外周听觉系统 的组成部分，连接着 耳蜗神经 [4]。 耳蜗的核心部分为 柯蒂氏器，是听觉传导器官，负责将来自 中耳 的声音信号转换为相应的神经电信号，交送脑的 中枢听觉系统 接受进一步处理，最终实现听觉 [5]。 耳蜗的病变和多种 听觉障碍 密切相关。 耳蜗位于 颞 …

The cochlea (pl.: cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral).

2023年4月1日 · The cochlea is a fluid-filled, spiral-shaped cavity found in the inner ear that plays a vital role in the sense of hearing and participates in the process of auditory transduction. Sound waves are transduced into electrical impulses that the …

2024年5月10日 · The cochlea is a fluid-filled, spiral-shaped cavity found in the inner ear. It plays an important role in the function of hearing. Conditions associated with the cochlea include sensorineural hearing loss, acoustic neuroma, and tinnitus.

There are six receptor organs located in the inner ear: cochlea, utricle, saccule, and the lateral, anterior, and posterior semicircular canals. In addition, in mammals, the cochlea is coiled, which has been shown to enhance low-frequency vibrations as they travel through the fluid-filled coil.

2025年2月12日 · Human ear - Cochlea, Hearing, Balance: The cochlea contains the sensory organ of hearing. It bears a striking resemblance to the shell of a snail and in fact takes its name from the Greek word for this object. The cochlea is a spiral tube that is coiled two and one-half turns around a hollow central pillar, the modiolus.

2024年8月22日 · Your cochlea is a snail-shaped organ within your inner ear that helps you hear. It’s filled with fluid that moves in response to sound waves and is split into three tubes by two thin membranes. One of these membranes — the basilar membrane — is like an elastic wall, on top of which sits the organ of Corti.

2023年10月30日 · The cochlea is a component of the labyrinth of the internal ear that is responsible for hearing. It is a hollow, spirally coiled chamber inside the temporal bone that makes 2.75 turns around its axis, which is called the modiolus. The cavity of the cochlea (cochlear canal) houses a triangular membranous duct, called the cochlear duct. The ...

The Cochlea. The principle auditory organ of the inner ear is the cochlea, shown in the inner ear diagram of Figure 3. Though spiral in shape, it is easiest to think about the cochlea by imagining it has been ``unrolled.''

The cochlea of the inner ear is the most critical structure in the auditory pathway, for it is there that the energy from sonically generated pressure waves is transformed into neural impulses. The cochlea not only amplifies sound waves and converts them into neural signals, but it also acts as a mechanical frequency analyzer, decomposing ...
