Specifically, A-alpha fibers carry proprioception while A-beta fibers carry fine touch.<\/p>\n<p>Slow fibers (A-delta and C fibers) are fibers of the anterolateral system, so carry pain and temperature information. A-delta fibers are lightly myelinated, so conducted slowly. C-fibers are unmyelinated, so their conduction velocity is the slowest. In fact, you often perceive a painful stimulus in two stages: the first, rapid sensation is carried by A-delta fibers and can mediate a withdrawal reflex (imagine touching a hot pan and pulling away immediately), the second slower sensation is carried by C-fibers and produces the long-lasting painful sensation (the burning &#8220;ow&#8221; sensation that comes half a second after touching the hot pan).<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Fibers within a peripheral nerve are classified by conduction speed and diameter.<\/p>\n","protected":false},"author":2,"featured_media":435,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"om_disable_all_campaigns":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[21],"tags":[],"aioseo_notices":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v22.0 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\n<title>Types of Sensory Fibers - DocNeuro<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/docneuro.com\/types-of-sensory-fibers\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"Types of Sensory Fibers - DocNeuro\" \/>\n<meta property=\"og:description\" content=\"Fibers within a peripheral nerve are classified by conduction speed and diameter.\" \/>\n<meta property=\"og:url\" content=\"https:\/\/docneuro.com\/types-of-sensory-fibers\/\" \/>\n<meta property=\"og:site_name\" content=\"DocNeuro\" \/>\n<meta property=\"article:publisher\" content=\"https:\/\/www.facebook.com\/DocNeuro\/\" \/>\n<meta property=\"article:published_time\" content=\"2013-03-29T19:28:48+00:00\" \/>\n<meta property=\"og:image\" content=\"https:\/\/docneuro.com\/wp-content\/uploads\/2013\/03\/Conduction-velocity.jpg\" \/>\n\t<meta property=\"og:image:width\" content=\"568\" \/>\n\t<meta property=\"og:image:height\" content=\"493\" \/>\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\n<meta name=\"author\" content=\"Naoum P.
