These nerves mediated the majority of inhibitory responses in the gi tract and regulate many important physiologicai reflexes , such as relaxation of the lower esophageal sphincter after swallowing , receptive relaxation of the proximal stomach during eating , and descending inhibition in response to distension 這些nanc能神經介導大多數胃腸道運動的抑制性反應,參與許多重要的生理反射,如吞咽之后的食管下括約肌舒張、進食后胃體的容受性舒張、消化道的下行性抑制反應及胃腸蠕動等。

While urinate the detrusor has the bladder contracted , inter and outer sphincters relax , the urine is released from the bladder , while ejaculate the amyofibre of prostate is contracted as well as the urethra inner sphincter is contracted to close the bladder neck and the outer sphincter opened , the semen is ejaculated outside . if the regulation is out of control , the inner sphincter wouldn t colse the bladder neck , instead the outer sphinecter is opened to close the door for the semen ejection , as result the semen only flows backward into the bladder , this is called “ reversed ejaculation “ . because the semen could not be ejaculated into vagina , the fecundation and bearing doesn t occur 當排尿時,逼尿肌收縮膀胱,內外括約肌放松,尿被排出體外射精時,前列腺肌纖維收縮的同時,尿道括約肌也收縮,關閉膀胱頸部,而外括約肌開放,精液便射出體外如果調節失控,內括約肌未關閉膀胱開口,而外括約肌反而收縮,關閉了遠端的門戶,結果精液只能倒流入膀胱,這就叫“逆行射精” ,精液未能射入陰道,也就不能受精生育。

It is concluded that most patients with fistula who underwent the procedure of ctu - back should be followed up to see if the - stage of operation is needed . in order to achieve a satisfactory function of defecation and continence , the main points of procedure are cutting off the total internal mucosa of fistula , suturing the defect in skin and repairing the sphincter when necessary 作者認為合并瘺管并經肛門后切術治療的部分患兒,應在術后一定時間行期手術,切除瘺管粘膜,縫合皮膚,必要時修補括約肌,以獲得術后更理想的肛門外觀與排便控制功能。

Results genitourinary dysfunction in msa comprised of impotence , urinary retention and incontinence resulted from a combination of detrusor hyperreflexia and urethral sphincter weakness followed by failure of detrusor contraction . mri and ct show brain atrophy 結果多系統萎縮在泌尿生殖系改變上表現為陽萎、尿潴留、尿失禁等,尿動力學檢查有膀胱逼尿肌反射亢進或無反射,影像學檢查有不同程度的腦萎縮。

This model shows the morphology of the stomach in a moderate distended state . with the longitudinal section , the model shows the structures of the gastric folds , pyloric valve , pyloric sphincter muscles , gastric mucosa and the transitional mucosa of the gastric - esophagus 本模型作縱剖,顯示胃在中等度膨脹時的形狀,顯示:黏膜壁、幽門瓣、幽門括約肌、胃黏膜以及由食管向胃移行之黏膜等構造。

Smoking can cause relaxation of the pyloric sphincter , the narrow passage between the stomach and the small intestine , allowing bile to regurgitate into the stomach and damage the mucous membrane of the stomach and duodenum 吸煙可引致幽門括約肌松弛和膽汁返流到胃部,令胃黏膜及十二指腸受損

The prostate constitutes the near urethra wall and urethral sphincter surrounding the urethra , the detrusor contracts and then the sphincter relaxes 前列腺構成近端的尿道壁和圍繞前列腺尿道部的尿道內括約肌,當排尿逼尿肌收縮時,內括約肌即放松。

The commonest intial symptoms were back pain and numbness over limbs , but later muscle weakness and sphincter disturbances came to predominate 起初最常見之癥狀為背痛及肢體麻木感,腫瘤常至肢體無力成大小便障礙出現時才被診斷出來。

The occurrence and pathogenesis of these complications following endoscopic retrograde cholangiopancreatography and sphincter of oddi manometry were discussed 在此陳述臨床病史,影像學所見,并討論這并發癥的發生率及可能致病機轉。
