自主神經(jīng)系統(tǒng)與情緒

1、自主神經(jīng)系統(tǒng)與情緒杜思雨2014.8.15自主神經(jīng)系統(tǒng)自主神經(jīng)系統(tǒng)（autonomic nervous system）是脊椎動物的末梢神經(jīng)系統(tǒng)，由軀體神經(jīng)分化、發(fā)展，形成機能上獨立的神經(jīng)系統(tǒng)。單一地或主要地由傳出神經(jīng)組成，受大腦的支配，但有較多的獨立性，特別是具有不受意志支配的自主活動，因此，蘭列（JNLangley1905）命名為自主神經(jīng)系統(tǒng)，另外也稱不隨意神經(jīng)系統(tǒng)或植物性神經(jīng)系統(tǒng)。自主神經(jīng)系統(tǒng)的組成自主神經(jīng)系統(tǒng)由交感神經(jīng)與副交感神經(jīng)兩個分支系統(tǒng)所構(gòu)成。交感系統(tǒng)與副交感系統(tǒng)共同控制與調(diào)節(jié)內(nèi)臟器官心臟、血管、胃、腸等，外部腺體唾液腺、淚腺、汗腺等以及內(nèi)分泌腺腎上腺、甲狀腺等的活動。 交感系統(tǒng)與

2、副交感系統(tǒng)的機能作用是對立的，二者互相起拮抗作用。這種作用使交感系統(tǒng)激活的有機體恢復平以限制和保存機體的能量消耗。交感神經(jīng)系統(tǒng)與副交感神經(jīng)系統(tǒng)機能活動比較自主神經(jīng)系統(tǒng)與情緒自主神經(jīng)系統(tǒng)的活動并非情緒產(chǎn)生的中樞機制，它的活動對情緒起著支持和延續(xù)的作用。在情緒刺激作用下，通過自主系統(tǒng)的活動，廣泛激活有機體各器官和組織，產(chǎn)生明顯的、超出常態(tài)生理節(jié)律的生理反應。自主神經(jīng)系統(tǒng)與情緒焦慮引起消化道蠕動減弱，消化液分泌被抑制憤怒引起腎上腺激素分泌增加，心血管活動加速，血壓、血糖升高，皮溫升高恐懼則導致外周血管收縮，面色蒼白，咽、口發(fā)干，皮溫下降，出冷汗等。情緒的生理測量Cardiovascular Meas

Differential association of sadness or grief with either predominant SNS or PNS activation might have been the result of having such different types of sadness as crying versus noncrying sadness or anticipatory versus acute sadness in mind.

15、ant autonomic changes ：Mood-unlike emotions that are associated with specific motivational functions, e.g., motivating to remove the object of anger or to escape from the object of fear, moods do not have specific and stable motivational functions, but only informational function.(心情主體所處在的感情狀態(tài)，比“情緒”延續(xù)時間長，感情波動不如“情緒”強烈) When addressing affective effects on ANS activity, it is therefore of utmost importance to distinguish mood from emotion i
