cables.<br>They transmit signals between the brain, spinal cord, and the rest of the body, allowing us to <strong>feel, move, see, hear, speak, swallow, and regulate internal organs<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">There are two main groups:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Spinal nerves<\/strong> \u2013 exit the spinal cord<\/li>\n\n\n\n<li><strong>Cranial nerves<\/strong> \u2013 exit directly from the brain<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Are Cranial Nerves?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Cranial nerves<\/strong> are nerves that arise directly from the brain or brainstem.<br>There are <strong>12 pairs (I\u2013XII)<\/strong>, and they mainly supply the <strong>head and neck<\/strong>, although some (especially the vagus nerve) extend to the chest and abdomen.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">They can be:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Sensory<\/strong> (sensation)<\/li>\n\n\n\n<li><strong>Motor<\/strong> (movement)<\/li>\n\n\n\n<li><strong>Mixed<\/strong> (both sensory and motor)<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Where Do Cranial Nerves Originate?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Most cranial nerves originate from the <strong>brainstem<\/strong>, which includes:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>the midbrain<\/li>\n\n\n\n<li>the pons<\/li>\n\n\n\n<li>the medulla oblongata<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">After emerging from the brainstem, they pass through specific <strong>openings in the base of the skull (foramina)<\/strong> to reach their target structures.<\/p>\n\n\n\n<figure class=\"wp-block-image
