These rami are part of the pathway by which sympathetic fibers travel to various organs.<\/li>\n\n\n\n<li><strong>Courses through spinal nerves<\/strong><br><strong>Answer: A. sympathetic division<\/strong><br>The sympathetic division utilizes spinal nerves to transmit nerve signals to peripheral organs. This is especially true for the sympathetic fibers that travel through the thoracolumbar region.<\/li>\n\n\n\n<li><strong>Has splanchnic nerves<\/strong><br><strong>Answer: A. sympathetic division<\/strong><br>Splanchnic nerves are part of the sympathetic division. They originate from the sympathetic trunk and carry fibers to the abdominal and pelvic organs.<\/li>\n\n\n\n<li><strong>Courses through cranial nerves<\/strong><br><strong>Answer: B. parasympathetic division<\/strong><br>The parasympathetic division utilizes cranial nerves, such as the vagus nerve (Cranial Nerve X), to transmit signals to organs like the heart, lungs, and digestive system.<\/li>\n\n\n\n<li><strong>Originates in cranial nerves<\/strong><br><strong>Answer: B. parasympathetic division<\/strong><br>The parasympathetic division has its origin in the cranial nerves (especially the vagus nerve) and the sacral spinal cord, which innervate various organs.<\/li>\n\n\n\n<li><strong>Effects enhanced by direct stimulation of a hormonal mechanism<\/strong><br><strong>Answer: A. sympathetic division<\/strong><br>The sympathetic division can enhance its effects via the release of epinephrine and norepinephrine from the adrenal medulla, which is part of the body&#8217;s fight-or-flight response.<\/li>\n\n\n\n<li><strong>Includes otic ganglion<\/strong><br><strong>Answer: B. parasympathetic division<\/strong><br>The otic ganglion is part of the parasympathetic division and is involved in parasympathetic innervation to the parotid gland, affecting salivation.<\/li>\n\n\n\n<li><strong>Includes celiac ganglion<\/strong><br><strong>Answer: A. sympathetic division<\/strong><br>The celiac ganglion is associated with the sympathetic division and provides sympathetic innervation to abdominal organs such as the stomach and liver.<\/li>\n\n\n\n<li><strong>Hypoactivity of this division would lead to a decrease in metabolic rate<\/strong><br><strong>Answer: B. parasympathetic division<\/strong><br>The parasympathetic division promotes energy conservation and a lower metabolic rate. Hypoactivity here could lead to reduced energy usage.<\/li>\n\n\n\n<li><strong>Has widespread, long-lasting effects<\/strong><br><strong>Answer: A. sympathetic division<\/strong><br>The sympathetic division tends to have more widespread and long-lasting effects on the body due to the release of hormones like adrenaline, which affect various organs simultaneously.<\/li>\n\n\n\n<li><strong>Sets the tone for the heart<\/strong><br><strong>Answer: B. parasympathetic division<\/strong><br>The parasympathetic division, particularly through the vagus nerve, helps to regulate the heart rate and set a baseline tone by slowing the heart rate.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"<p>A. sympathetic divisionB. parasympathetic divisionC. both sympathetic and parasympatheticD.
