Enkephalins specifically function as <strong>inhibitory neurotransmitters<\/strong> in the central nervous system. They belong to a larger group called <strong>endorphins<\/strong> or endogenous opioids\u2014chemicals produced naturally by the body that reduce pain and promote a sense of well-being.<\/p>\n\n\n\n<p>Enkephalins bind to <strong>opioid receptors<\/strong> in the brain and spinal cord, especially the <strong>mu and delta opioid receptors<\/strong>, which are responsible for <strong>modulating pain perception<\/strong>. When enkephalins are released in response to painful stimuli, they <strong>inhibit the release of substance P<\/strong>, a neurotransmitter that transmits pain signals to the brain. By blocking this pathway, enkephalins effectively <strong>reduce the sensation of pain<\/strong> and promote analgesia (pain relief).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Other Options Explained:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>a) Acetylcholine<\/strong>: A neurotransmitter involved in muscle activation and parasympathetic nervous system functions. It is typically <strong>excitatory<\/strong>, not inhibitory.<\/li>\n\n\n\n<li><strong>b) Tryptophan<\/strong>: An <strong>amino acid<\/strong>, not a neurotransmitter or neuropeptide. It is a precursor to serotonin but not directly involved in pain modulation.<\/li>\n\n\n\n<li><strong>c) Norepinephrine<\/strong>: A <strong>neurotransmitter and hormone<\/strong> that plays a role in the fight-or-flight response. It can have both excitatory and inhibitory effects depending on the receptor, but it\u2019s not primarily associated with pain reduction.<\/li>\n\n\n\n<li><strong>e) Serotonin<\/strong>: A <strong>monoamine neurotransmitter<\/strong> that regulates mood, appetite, and sleep. It may play a role in modulating pain, but not as directly or strongly as enkephalins.<\/li>\n\n\n\n<li><strong>f) Substance P<\/strong>: This is the <strong>opposite of enkephalins<\/strong>; it <strong>transmits pain<\/strong> signals rather than inhibits them.<\/li>\n\n\n\n<li><strong>g) Histamine<\/strong>: A compound involved in immune responses, also linked with inflammation and sometimes <strong>pain enhancement<\/strong>, not reduction.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p>Thus, <strong>enkephalins<\/strong> are the correct answer because they are inhibitory neuropeptides that <strong>reduce pain<\/strong> through opioid receptor binding.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of these is a neuropeptide that is generally inhibitory and can reduce sensations of pain? options: a) acetylcholine b) tryptophan c) norepinephrine d) enkephalins e) serotonin f) substance P g) histamine The correct answer and explanation is: Correct Answer: d) enkephalins Explanation (300 words): Enkephalins are a type of neuropeptide, which are small protein-like [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-21381","post","type-post","status-publish","format-standard","hentry","category-quiz-questions"],"_links":{"self":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21381","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/comments?post=21381"}],"version-history":[{"count":2,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21381\/revisions"}],"predecessor-version":[{"id":21383,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/posts\/21381\/revisions\/21383"}],"wp:attachment":[{"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/media?parent=21381"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/categories?post=21381"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/gaviki.com\/blog\/wp-json\/wp\/v2\/tags?post=21381"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
