Appetite stimulant - Wikipedia
An orexigenic, or appetite stimulant, is a drug, hormone, or compound that increases appetite and may induce hyperphagia. This can be a medication or a naturally occurring neuropeptide hormone, such as ghrelin, orexin or neuropeptide Y, [1] [2] which increases hunger and therefore enhances food consumption.
Orexigenic - an overview | ScienceDirect Topics
'Orexigenic' refers to hypothalamic neuropeptides that increase food intake and play a role in regulating food intake and energy balance in the body. AI generated definition based on: Current Opinion in Pharmacology, 2001
Network of hypothalamic neurons that control appetite - PMC
Specifically, two distinct neuronal populations exist in the arcuate nucleus of hypothalamus (ARH): the anorexigenic (appetite-suppressing) pro-opiomelanocortin (POMC) neurons and the orexigenic (appetite-increasing) neuropeptide Y (NPY)/agouti-related peptide (AgRP) neurons.
Appetite stimulants: Types, tips, and tricks - Medical News Today
2023年3月30日 · Appetite stimulants are medications, supplements, or other substances that increase feelings of hunger. An appetite stimulant is also known as an orexigenic. Some manufacturers specifically...
Physiological Role of Orexinergic System for Health - PMC
Orexins, or hypocretins, are excitatory neuropeptides involved in the regulation of feeding behavior and the sleep and wakefulness states. Since their discovery, several lines of evidence have highlighted that orexin neurons regulate a great range of physiological functions, giving it the definition of a multitasking system.
The physiological role of orexin/hypocretin neurons in the …
Orexins (hypocretins) directly interact with neuropeptide Y, POMC and glucose-responsive neurons to regulate Ca 2+ signaling in a reciprocal manner to leptin: orexigenic neuronal pathways in the mediobasal hypothalamus.
An orexigenic subnetwork within the human hippocampus
2023年8月30日 · Here we combine tractography, intracranial electrophysiology, cortico-subcortical evoked potentials, and brain-clearing 3D histology to identify an orexigenic circuit involving the lateral...
Appetite regulation and weight control: the role of gut hormones
2012年1月16日 · This review discusses the central mechanisms involved in body weight regulation and explores a suite of well characterized and intensely investigated anorexigenic and orexigenic gut hormones.
Orexigenic - an overview | ScienceDirect Topics
Numerous bioregulators have been described that stimulate or inhibit appetite and feeding behavior. Bioregulators that stimulate appetite and feeding are termed orexigenic agents (orexin, appetite; genesis, beginning), whereas those that suppress appetite and feeding are termed anorexigenic agents. These factors are summarized in Tables 12.1 ...
Novel functions of orexigenic hypothalamic peptides: From genes …
Here, we present a brief review of some of this work and highlight the novel functions for central orexigenic neuropeptides. We review evidence that organisms engage in critical regulatory behaviors both before an after ingestion has occurred.
