WebJul 16, 2024 · Vagal afferent neurons (VAN), located in the nodose ganglion (NG) innervate the gut and terminate in the nucleus of solitary tract (NTS) in the brainstem. They are the primary sensory neurons integrating gut-derived signals to regulate meal size. Chronic high-fat diet (HFD) consumption impairs vagally mediated satiety, resulting in overfeeding. WebFeb 11, 2024 · Afferent fibers form the axons of sensory neurons and carry impulses to the central nervous system (CNS). They are further categorized based on their size and …
WebIn some experiments, slowly conducting fibers ( Aδ and/or C ) were found to provide most or all of the excitatory drive to neurons of the dorsal horn's marginal zone (Rexed's lamina I) in a cat. A similar set of experiments in a monkey provides additional information on the excitatory projection of afferent units with fine fibers. A type Ia sensory fiber, or a primary afferent fiber is a type of afferent nerve fiber. It is the sensory fiber of a stretch receptor called the muscle spindle found in muscles, which constantly monitors the rate at which a muscle stretch changes. The information carried by type Ia fibers contributes to the sense of proprioception.
