Hey, everyone. Let's take a look at this question together which of the following statements about the frantic nerve is true. Is it answer choice? A it is a major component of the parasympathetic nervous system influencing various organs such as the heart, lungs and the digestive tract. Answer choice B, it transmits visual information from the retina to the brain. Answer choice C it controls voluntary muscle movements and transmit sensory information from the skin muscles and joints to the central nervous system or answer choice D it arises from the cervical spine and controls the diaphragm playing a crucial role in breathing and respiration. Let's work this problem out together to try to figure out which of the following answer choices contains a statement about the frantic nerve. That is true. So in order to solve this question, we have to recall what we have learned about the frenetic nerve to determine which of the following statements is a true statement starting off with answer choice. A which says that it is a major component of the parasympathetic nervous system influencing various organs such as the heart, lungs and the digestive tract. Well, in statement, a we can identify that it is a false statement since the fren nerve is not a major component of the parasympathetic nervous system. And instead the Fren nerve is a major component of the somatic nervous system and is involved in controlling the diaphragm for breathing. So, answer choice A is incorrect. Next, we have statement B which says that it transmits visual information from the retina to the brain. Well, we can identify that statement B is also a false statement. Since the transmission of visual information from the retina to the brain is transmitted by the optic nerve and not the frantic nerve. So answer choice B is also incorrect. And next, we have statement C which says that the fren nerve controls voluntary muscle movements and transmits sensory information from the skin muscles and joints to the central nervous system. And we are able to identify that statement. C is a false statement since we know from determining that statement, A is also a false statement that the Fren nerve is involved in controlling the diaphragm for breathing, which the controlling of the diaphragm for breathing requires involuntary muscle and not the control of voluntary muscle movements. So answer choice C is also incorrect. Leaving us with only one remaining answer choice, which is answer choice D which answer choice D says that it arises from the cervical spine and controls the diaphragm playing a crucial role in breathing and respiration, which is a true statement since the Fren nerve originates from the cervical spine and travels down through the neck and chest to reach the diaphragm, which is the primary muscle involved in breathing. So answer choice D is the only statement here. That is a true statement about the Freni nerve. So answer choice D is the correct answer. I hope you found this video to be helpful. Thank you and goodbye.
