Olfaction

40.5K
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.
The olfactory receptors are embedded in the cilia of the...

Olfactory Receptors: Location and Structure

10.6K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

Physiology of Smell and Olfactory Pathway

13.2K
Humans detect odors with the help of specialized cells located in the upper part of the nasal cavity, called olfactory receptor neurons (ORNs). ORNs possess hair-like structures called cilia, which are receptive to sensations from the inhaled air. When an odorant molecule binds to a specific receptor on the cell of the cilia, it leads to a series of events that ultimately cause the ORN to send electrical signals to the olfactory bulb in the brain through the olfactory nerves.
The olfactory...

概括

经典的嗅觉训练在COVID-19后显著改善了嗅觉功能障碍,超过了多感官方法. 两种训练类型都有助于嗅觉功能,但只有经典训练在对照组中表现出明显的优势.

  • 神经学 神经学
  • 耳鼻喉科 耳鼻喉科 耳鼻喉科
  • 传染性疾病 传染性疾病

背景情况:

  • 嗅觉功能障碍 (OD) 影响30-60%的COVID-19幸存者,其中15-20%的人经历了持续的症状.
  • 嗅觉训练已经显示出病毒诱导的OD的前景,但多感官方法的有效性仍在研究中.

研究的目的:

  • 为了比较多感官嗅觉训练 (涉及嗅觉,味觉和视觉) 与古典嗅觉训练对持续后COVID-19 OD 的有效性.
  • 评估这些培训方法对嗅觉功能和生活质量的影响.

主要方法:

  • 68名患有COVID-19后持续性OD的参与者被随机分为三个组:经典的嗅觉训练,多感官嗅觉训练或对照组.
  • 训练包括嗅到特定的气味 (古典) 或经历一致的嗅觉,味觉和视觉刺激 (多感官) 每天两次,持续12周.
  • 在干预前和后评估了嗅觉功能和生活质量.

主要成果:

  • 与基线相比,古典和多感官嗅觉训练组都显示了嗅觉功能的显著改善.
  • 干预组之间没有观察到生活质量改善的显著差异.
  • 经典的嗅觉训练与对照组相比,嗅觉功能得到了显著的改善.

结论:

  • 经典和多感官嗅觉训练都可能有利于改善后病毒性OD患者的嗅觉功能.
  • 与多感官训练和控制相比,经典的嗅觉训练似乎是一个更强大的干预措施,用于增强嗅觉功能.
  • 需要进一步的研究来探索多感官培训对生活质量的长期影响和潜在益处.
