[ArchivalUser]

bcoz pudendal nerve gives its terminal branch in rectum .....inferior rectal nerves

[ArchivalUser]

yes because pudenal nerve also innervate external anal sphincter

[ArchivalUser]

so, ccc may be the correct

[ArchivalUser]

@dramitk57

these are Two separate statements:

1-An inability to empty the rectum

2-wkness in control over rectum emptying

[ArchivalUser]

m confused ,so cc or dd can be the answer here

[ArchivalUser]

don't be confuse it simple guys, first the answer is DDD
second if he says as sarim says (weakness in control over rectum empty) then it could be confusing litle bit, coz pudenal nerve responsible for vouluntatry control of external sphincter

Pudendal Nerve (S2-S3-S4 ---- Somatic nerve):


A-Innervating "External Urethral Sphincter"(skeletal muscle)-- a "Voluntary Sphincter"

-this is what gives u "Voluntary Control" over bladder emptying.
-In pudendal Block,

*there is a "Wkness of the voluntary sphincter of the bladder" or
*"Urinary Incontinence" or
*"Loss of voluntary control over bladder emptying''

(All three statements stating the same thing)

B-Innervating "External ANAL Sphincter"(skeletal muscle)-- a "Voluntary Sphincter"

-this is what gives u "Voluntary Control" over Rectum emptying.
-In pudendal Block,

*there is a "Wkness of the voluntary sphincter of the Anus" or
*"Fecal Incontinence" or
*"Loss of voluntary control over Rectum emptying''

(All three statements stating the same thing)
