Hey, everyone. Let's take a look at this question together match the information in column one with column two. And here we can see in column one, we have a list of six different terms. And in column two, we have a list of six different definitions and we want to match those definitions in column two with the correct terms in column one. So first, let's take a look at the definitions in column two to try to match them with their correct term in column one, starting off with letter M, it says provide sympathetic innervation to the abdominal organs, pelvic organs and lower limbs. While we can recall that the ganglia that is responsible for providing that sympathetic innervation to the abdominal organs, pelvic organs as well as the lower limbs is the lumbar ganglia, which is number five. So we can go ahead and put an M next to number five in column one and cross off M in column two. Next, we have letter N which says innervate the pelvic organs, lower limbs and some structures in the abdomen, which we note that the ganglia responsible for the innervation of those pelvic organs, lower limbs and some structures in the abdomen are the sacro ganglia. And looking at column one, we can see that the sacro ganglia is number six. So next to number six, we can put the letter N and cross it off in column two. Next we have letter O which says innervates structures in the head, neck and face, including the dilator muscle of the iris and sweat. Glance. Well, we can recall that the ganglion responsible for the innervation of those structures in the head, neck and face, which include the dilator muscle of the iris, and the sweat glands are the superior cervical ganglion, which we can see is number one. So next to number one in column one, we can put the letter O and cross it off in column two. Next we have letter P which says innervates structures in the chest and upper limbs, including the heart and blood vessels. Well, we can recall that the ganglion responsible for the innovation of those structures in the chest and upper limbs, which include the heart and the blood vessels are the inferior cervical ganglion, which we can see in column one is number three. So next to number three in column one, we can put the letter P and cross it off in column two. Next, we have letter Q which says provides sympathetic innervation to the heart and blood vessels in the neck and upper extremities. Well, we can recall that the ganglion responsible for providing that sympathetic innervation to the heart and blood vessels in the neck and upper extremities, which are also found in the cervical area are the middle cervical gang leon, which is number two. So next to number two, we can put the letter Q and cross it off in column two, which leaves us with only one remaining option in column one, which is number four, the thoracic ganglia. And in column two, we have letter R which says innervate the organs and structures of the chest, including the heart, lungs and blood vessels, which we know is the thoracic ganglia. So we can put letter R next to number four in column one and cross it off in column two, giving us the complete match in column one for each term with their correct definition. So this is the correct order. I hope you found this video to be helpful. Thank you and goodbye.
