<p>CSV import</p> <p><b>New page</b></p><div>== Extensor ==<br /> '''Extensor''' (/ɪkˈstɛnsər/), from the Latin ''extendere'' meaning &quot;to stretch out&quot;, is a term used in [[anatomy]] to refer to a muscle whose contraction extends or straightens a limb or other part of the body.<br /> <br /> === Etymology ===<br /> The term ''extensor'' is derived from the Latin verb ''extendere'', which means &quot;to stretch out&quot;. This is a combination of ''ex-'', meaning &quot;out&quot;, and ''-tendere'', meaning &quot;to stretch&quot;.<br /> <br /> === Function ===<br /> An extensor muscle is any muscle used to straighten out a limb or a joint. In contrast, a [[flexor]] is a muscle that does the opposite, it flexes or bends a limb or joint. Extensor muscles are located in various parts of the body, including the [[arm]], [[leg]], [[spine]], and [[neck]].<br /> <br /> === Examples ===<br /> Some examples of extensor muscles include:<br /> <br /> * [[Extensor carpi radialis longus]]: This muscle of the forearm helps in the extension and abduction of the wrist.<br /> * [[Extensor digitorum]]: This muscle extends the fingers and is found in the forearm.<br /> * [[Extensor hallucis longus]]: This muscle is located in the leg and helps in extending the big toe and dorsiflexing the foot.<br /> <br /> === Related Terms ===<br /> * [[Flexor]]: A muscle that serves to flex or bend a part of the body.<br /> * [[Muscle contraction]]: The activation of tension-generating sites within muscle fibers.<br /> * [[Anatomy]]: The branch of science concerned with the bodily structure of humans, animals, and other living organisms.<br /> <br /> [[Category:Anatomy]]<br /> [[Category:Muscular System]]<br /> {{dictionary-stub}}</div>
