In addition to nerve endings, pleasure from anal intercourse may be aided by the close proximity between the anus and the prostate for males, and The upper anal canal contains a high density of free and organized sensory nerve endings including Meissner’s corpuscles (touch), Krause’s bulbs (cold), Golgi-Mazzoni bodies The anal canal is the digestive system’s endpoint, and it plays a crucial part in continence. Pudendal nerve, its course through the lesser sciatic foramen, and branches, including inferior anal at bottom right. [1] They play a vital role in the innervation of the lower anus The nerve provides sensory innervation to the anal canal inferior to the pectinate line and motor innervation to the external anal sphincter. The inferior rectal nerve (inferior anal nerve, inferior haemorrhoidal nerve) is a nerve of the perineal region. We performed a comprehensive and up-to-date review of the published literature on anorectal neuroanatomy to generate our findings. The controversies Der Analreflex stellt einen Fremdreflex am äußeren Afterschließmuskel ausgehend von den Rückenmarkssegmenten S3 bis S5 dar.
