To understand this, let\u2019s break down the function and anatomy of the relevant muscles:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>1. Flexor Carpi Ulnaris:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Location<\/strong>: Runs along the ulnar (medial) side of the forearm.<\/li>\n\n\n\n<li><strong>Primary Functions<\/strong>:\n<ul class=\"wp-block-list\">\n<li><strong>Flexes the wrist<\/strong> (bends the hand toward the forearm).<\/li>\n\n\n\n<li><strong>Adducts the wrist<\/strong> (moves the hand toward the midline, or ulnar side, of the body).<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Insertion<\/strong>: Pisiform, hook of hamate, and base of the 5th metacarpal.<\/li>\n<\/ul>\n\n\n\n<p>Since it pulls the wrist both downward (flexion) and medially (adduction), it&#8217;s the only option that does both.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Palmaris Longus:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Function<\/strong>: Primarily assists in <strong>flexing the wrist<\/strong>, but <strong>does not adduct<\/strong> or abduct.<\/li>\n\n\n\n<li><strong>Not everyone has this muscle<\/strong> (it is absent in about 10-15% of the population).<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Flexor Digitorum (Superficialis\/Profundus):<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>These muscles <strong>flex the fingers<\/strong>, especially the <strong>interphalangeal joints<\/strong>, and assist in wrist flexion.<\/li>\n\n\n\n<li>They <strong>do not adduct<\/strong> the wrist.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4. Flexor Carpi Radialis:<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Function<\/strong>: <strong>Flexes and <em>abducts<\/em><\/strong> the wrist (moves it toward the thumb side, or radial side).<\/li>\n\n\n\n<li>This is the <strong>opposite<\/strong> of adduction, so it is <strong>not correct<\/strong>.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Conclusion:<\/strong><\/h3>\n\n\n\n<p>Among the listed options, <strong>only the flexor carpi ulnaris<\/strong> performs <strong>both flexion and adduction<\/strong> of the wrist.
