Editing Perineum (section)

===Areas===
The perineum region can be considered a distinct area from the pelvic cavity, with the two regions separated by the [[pelvic diaphragm]]. The perianal area (''[[wikt:peri-#Prefix|peri-]]'' and ''[[anus|anal]]'') is a subset of the perineum. The following areas are thus classified as parts of the perineal region:
* perineal pouches: superficial and deep (see above for details)
* [[ischioanal fossa]]&nbsp;– a fat-filled space at the lateral sides of [[anal canal]], bounded laterally by the obturator internus muscle, and medially by the pelvic diaphragm and anal canal; its base is the skin
** [[anal canal]]
** [[pudendal canal]]&nbsp;– contains [[internal pudendal artery]] and the [[pudendal nerve]]
