In physiology, a chemoreceptor detects changes in the normal environment, such as an increase in blood levels of carbon dioxide (hypercapnia) or a decrease in blood levels of oxygen (hypoxia), and transmits that information to the central nervous system which engages body responses to restore homeostasis.

2024年12月11日 · Chemoreceptors are specialized sensory cells, sensitive to molecules, that detect chemical changes in the body, responding to chemical stimuli and interpreting them into electrical impulses.

化学受体（chemoreceptor）又被称为 甲基受体趋化性蛋白 （methyl-accepting chemotaxis protein），其作用是帮助微生物细胞感应化学物质浓度的变化。 典型的趋化受体蛋白是大肠杆菌的Tar和Tsr。 它们以二聚体的形式存在于细胞膜上，二聚体也构成了趋化受体的基本结构单元。 通过对趋化受体周质空间区域和细胞质区域的X晶体衍射分析表明，它们是由复杂的四股α螺旋构成（每个单体两股螺旋）。 一个完整的大肠杆菌MCP长度大约是380-Å，周质空间区域80-Å， …

A chemoreceptor is defined as a sensory receptor associated with cnidocytes that is highly sensitive to detect chemical scents of organisms and chemicals released by wounded prey, modulating the discharge of nematocysts.

Chemoreceptors are proteins or protein complexes that bind molecules detected at distance and generally at low concentration (olfaction) or molecules detected at proximity and often at higher concentrations (gustation), respectively volatile and not volatile for organisms living in …

Peripheral chemoreceptors (carotid and aortic bodies) and central chemoreceptors (medullary neurons) primarily function to regulate respiratory activity. This is an important mechanism for maintaining arterial blood PO 2, PCO 2, and pH within appropriate physiological ranges.

Chemoreceptors are special nerve cells that detect changes in the chemical composition of the blood and send information to the brain to regulate cardiovascular and respiratory functions. There are two major types, which are peripheral and central chemoreceptors. The main peripheral chemoreceptors are the aortic and carotid bodies.

2024年10月10日 · Chemoreceptors detect chemical changes within the body and its environment, providing feedback for maintaining physiological balance. These sensory receptors are involved in processes such as respiration, taste, and smell. Understanding their function is important for comprehending biological mechanisms and potential medical applications.

Chemoreceptor regulation of breathing is a form of negative feedback. The goal of this system is to keep the pH of the blood stream within normal neutral ranges, around 7.35. A chemoreceptor, also known as chemosensor, is a sensory receptor that transduces a …

Chemoreceptors are sensors that detect changes in arterial blood gases or chemical composition. You might find these chapters and articles relevant to this topic. Chemoreceptors are at the beginning of chemosensory signaling cascades that correspond to a …
