Orexin (/ ɒ ˈ r ɛ k s ɪ n /), also known as hypocretin, is a neuropeptide that regulates arousal, wakefulness, and appetite. [5] It exists in the forms of orexin-A and orexin-B.The most common form of narcolepsy, type 1, in which the individual experiences brief losses of muscle tone ("drop attacks" or cataplexy), is caused by a lack of orexin in the brain due to destruction of the cells ...
The endogenous orexin neuropeptides, orexin A and orexin B, are involved in the regulation of sleep–wake cycles and act to promote wakefulness. [33] [16] [7] Deficiency of orexin signaling is thought to be the primary cause of the sleep disorder narcolepsy. [33] [16] Disturbances in orexin signaling may also be involved in insomnia. [33]
Ornithine transcarbamylase deficiency also known as OTC deficiency is the most common urea cycle disorder in humans. Ornithine transcarbamylase , the defective enzyme in this disorder, is the final enzyme in the proximal portion of the urea cycle , responsible for converting carbamoyl phosphate and ornithine into citrulline .
The lateral hypothalamus (LH), also called the lateral hypothalamic area (LHA), [1] contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; [2] this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature ...
Orexin, otherwise known as hypocretin, is a neuropeptide that acts within the brain to regulate appetite and wakefulness as well as a number of other cognitive and physiological processes. [27] [38] [39] Loss of these orexin-producing neurons causes narcolepsy and most individuals with narcolepsy have a reduced number of these neurons in their ...
Rosemary Oil. A very common oil included in natural hair growth products, studies have noted the efficacy of rosemary in promoting hair growth. In one study, results showed that rosemary oil may ...
Orexin deficiency has been identified as responsible for narcolepsy. [ 10 ] Research suggests that orexin and histamine neurons play distinct, but complementary roles in controlling wakefulness with orexin being more involved with wakeful behavior and histamine with cognition and activation of cortical EEG .
Chatting with humans is a sign of affection, even though many times it sounds like complaining and arguing, much like with our human children! The AKC has this to say about vocal Huskies, ...
