这关键区别between crista and maculais that crista is a sense organ present in the ampullae of the semicircular canals of the inner ear, while macula is a sensory spot present in the walls of theaccule在内耳的前庭内。
克里斯塔(Crista)和黄斑是内耳中前庭系统的两个重要部分。人类中的前庭系统执行基本任务。它参与了许多重要的反射途径,这些途径负责在身体位置进行运动和调整。它还进行了反射途径,可以帮助大脑提供对重力和身体运动的感知。

什么是克里斯塔?
克里斯塔(Crista)是内耳半圆形管的截肢中存在的一种理智器官。它也被称为crista ampullaris,它是旋转的感觉器官。内耳有三对crista。CRISTA的正常功能是感知沿管平面的角度加速度和减速。
内耳有三个专业的地区membranous labyrinth (fluid-filled tubes and chambers that are the receptors for the senses of equilibrium and hearing). They are the utricle, saccule, and semicircular canals, which are also known as vestibular organs. The inner ear also has a cochlear duct, which is involved in a special sense of hearing. Semicircular canals are filled with a fluid called endolymph due to its connection with the cochlear duct via saccule, which also normally contain endolymph. Moreover, semicircular canals also contain an inner membranous sleeve that lines the semicircular canals. Furthermore, semicircular canals contain crista ampullaris. The crista ampullaris is a cone-shaped structure covered in receptor cells called hair cells. Crista ampullaris is covered by a gelatinous mass known as the cupula. When there is angular acceleration or rotation, the endolymph in the semicircular canals deflects the cupula against the hair cells of the crista ampullaris. Thus, the hair cells respond by stimulating神经元(前庭神经)支配它们。
什么是黄斑?
黄斑是内耳前庭内扫被的壁中存在的感官斑点。实际上,黄斑基本上是毛细胞。Its normal function is to detect linear acceleration in a vertical plane. Saccule and utricle are present in the vestibule region of the inner ear. Each saccule and utricle contain a macula to detect linear acceleration.
这macula of the saccule lies in a vertical position. A macula is a 2 mm by 3 mm patch of hair cells. Moreover, each hair cell of the macula contains 40 to 70 stereocilia and one true cilium. The true cilium is known as kinocilium. The tips of the stereocilia and one true cilium are covered by a gelatinous cover known as an otolithic membrane. Furthermore, the otolithic membrane has small, densely packed protein-calcium carbonate granules called statoconica.
克里斯塔和黄斑之间有什么相似之处?
- 克里斯塔(Crista)和黄斑是内耳中前庭系统的两个重要部分。
- 两者都有毛细胞。
- 两者在保持平衡和结束平衡方面起关键作用。
- 他们参与控制加速度。
- Both are covered by gelatinous mass or cover.
克里斯塔和黄斑有什么区别?
克里斯塔(Crista)是内耳半圆形管的截肢中存在的一种理智器官,而黄斑是内耳前庭内囊的壁上存在的感官斑点。因此,这是Crista和Macula之间的关键区别。此外,Crista负责控制角加速度,而黄斑负责控制线性加速度。

摘要 - Crista vs Macula
Crista和Macula是内耳前庭系统的两个重要部分。克里斯塔(Crista)是内耳半圆形管的截肢中存在的一种理智器官。它有助于感知沿管平面的角度加速度和减速。黄斑是内耳前庭内扫被的壁中存在的感官斑点。它有助于检测垂直平面中的线性加速度。因此,这总结了Crista和Macula之间的区别。
