※ 引述《rbhank30 (X)》之銘言： : 【問題1】：Ch49 Nervous System No.47 : 47) After suffering a stroke, a patient can see objects anywhere in front of : him, but pays attention only to objects in his right field of vision. : When asked to discribe these objects, he has difficulty judging their size and : distance. What part of the brain was likely damaged by the stroke? : A) the left frontal lobe : B) the right frontal lobe : C) the left parietal lobe : D) the right parietal lobe : Ans: D : 【個人看法】： : 1. 因為他只對右邊的物體有所反應,因此左腦正常,右腦出問題, : A,C選項先刪除 : 2. 剩下額業和頂葉的判斷, 小弟選的是 B 選項, 因為額葉與判斷有關, 頂葉 : 記得是主要體感覺區, 因此與答案不同, 麻煩高手指正是否有沒考慮到的地方。 : 【問題2】: Ch49 Nervous System No.61 你的[個人看法]1.是正確的判斷但是[個人看法]2.卻是對於腦區認識上的不完整, 以下擷取得有點長,但值得細讀 (擷取自Wiki) #Frontal Lobe: The executive function of the frontal lobes involve the ability to recognize future consequences resulting from current actions, to choose between good and bad actions (or better and best), override and suppress socially unacceptable responses, and determine similarities and differences between things or events. The frontal lobes also play an important part in retaining longer term memories which are not task-based. #Parietal Lobe The parietal lobe plays important roles in integrating sensory information from various parts of the body, knowledge of numbers and their relations, and in the manipulation of objects. Its function also includes processing information relating to the sense of touch. Portions of the parietal lobe are involved with visuospatial processing. Although multisensory in nature, the posterior parietal cortex is often referred to by vision scientists as the dorsal stream of vision (as opposed to the ventral stream in the temporal lobe). 無法判斷size和distance 是sensory integration的問題, 與frontal lobe的function無關 (到這裡可以理解嗎?) 可以看看醫界怎麼說: http://www.patient.co.uk/doctor/space-occupying-lesions-of-the-brain (找Parietal Lobe ) : 61) C.elegans is a model organism and was the first eukaryotic organism to : have its genome sequenced. The free-living nematode is often used in labs : investigating nervous system development with all 302 of its neurons and : their effectors categorized. Interesting control mechanisms have been : investigated with reproduction, particularly with egg-laying in the nematode. : There are 16 muscles, 2 types of neurons, and multiple receptors involved in : the process of laying eggs in C.elegans, and there are mutations in all of : those structures for the study of the process. One particular mutation that : prevents the laying of eggs by the worm is rescued by the neurotransmitter, : serotonin. That rescue suggests that the mutation is most likely in which of : the following? : A) a post-synaptic neuron involved in egg-laying : B) a pre-synaptic neuron involved in egg-laying : C) a receptor for serotonin on cells needed for egg-laying : D) one of the muscles needed for egg-laying : Ans: 這題出現兩次,題目一模一樣,選項也一樣,但給的答案不同,在Ch48第63題答案給A : 然而Ch49第61題答案給B : 【個人看法】：依題目所說serotonin為一種neurontransmitter,因此能分泌神傳的細胞 : 皆有可能, 因此A,B答案都有可能, 突觸前神經元能分泌讓突觸後接收, 也可能是突觸後 : 神經元分泌讓下面的細胞接收; C選項排除, 因若是receptor壞掉, 加入ligand一樣不會 : 有反應。個人是選 B 答案, 煩請高手解答, 謝謝。我的判斷是 B: C,D先刪掉, "One particular mutation that prevents the laying of eggs by the worm is rescued by the neurotransmitter,serotonin " 這代表 1. 原本可以分泌serotonin (或在此同等功效的神經傳導物質) 的 pre-synaptic neuron 功能失常了 2. 可以接收 serotonin 的 post-synaptic neuron 尚且功能正常我猜這個考題出自這裡: WormBook: The Online Review of C. elegans Biology http://www.ncbi.nlm.nih.gov/books/NBK19787/ ▄▁ -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 140.113.136.217 ※ 文章網址: http://www.ptt.cc/bbs/Biology/M.1401514991.A.8D1.html
