- 静脉系统研究研究
背景情况:
- 步态分析往往忽略了斜面平面的参数,而是专注于横面平面进行平衡评估.
- 前体系统在平衡中的作用主要是通过横平面行走指标来研究,忽视了斜面平面动态.
- 本研究探讨了乳头震动 (MV) 对最低脚清除 (MTC) 和其变化的未经探索的影响.
研究的目的:
- 为了确定不同类型的乳头震动 (MV) 如何影响最小脚距 (MTC).
- 分析单边和双边MV对MTC波动量和结构的影响.
- 测试有关MV对MTC减少和MTC变化模式的影响的假设.
主要方法:
- 20名年轻成年人进行了三项随机的行走任务:正常,单边MV和双边MV.
- 一个高分辨率的运动捕捉系统在移动过程中记录了脚的最小距离 (MTC).
- 使用变化系数 (数量) 和样本 (结构) 来量化MTC变化.
主要成果:
- 与正常行走相比,单边和双边MV都显著降低了MTC.
- 单边MV增加了MTC波动的数量和结构.

01:13The Cochlea
41.0K
The cochlea is a coiled structure in the inner ear that contains hair cells—the sensory receptors of the auditory system. Sound waves are transmitted to the cochlea by small bones attached to the eardrum called the ossicles, which vibrate the oval window that leads to the inner ear. This causes fluid in the chambers of the cochlea to move, vibrating the basilar membrane.

01:11The Auditory Ossicles
3.9K
The auditory ossicles of the middle ear transmit sounds from the air as vibrations to the fluid-filled cochlea. The auditory ossicles consist of two malleus (hammer) bones, two incus (anvil) bones, and two stapes (stirrups), one on each side. These bones develop during the fetal stage and are the ones to ossify first. They are fully mature at birth and do not grow afterward.
The aptly named stapes look very much like a stirrup. The three ossicles are unique to mammals, and each plays a role in...

Consider two sources of sound, that may or may not be in phase, emitting waves at a single frequency, and consider the frequencies to be the same.
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

01:16Anatomy of the Ear
11.5K
Auditory sensation, commonly called hearing, involves the transformation of sonic waves into neural impulses facilitated by the structures of the auditory organ. The prominent, flesh-like structure on the side of the head, called the auricle, directs sound waves towards the auditory canal. The auricle is often mislabeled as the pinna, a term more aligned with mobile structures like a feline's external ear. The auditory canal penetrates the cranium via the external auditory meatus of the...

01:15Equilibrium and Balance
6.2K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
