Inferior anal nerves
(Redirected from Nervi rectales inferiores)
Inferior anal nerves (also known as inferior rectal nerves) are branches of the Pudendal nerve that innervate the anus.
Etymology[edit | edit source]
The term "Inferior anal nerves" is derived from the Latin words "inferior" meaning lower, "anal" pertaining to the anus, and "nerves" referring to the fibrous cords that transmit signals in the body.
Anatomy[edit | edit source]
The Pudendal nerve branches off into the inferior anal nerves after it exits the Alcock's canal. These nerves then travel to the Ischiorectal fossa, a fat-filled space located near the anus. From there, they innervate the External anal sphincter and the skin around the anus.
Function[edit | edit source]
The primary function of the inferior anal nerves is to provide sensory and motor innervation to the External anal sphincter. This allows for the regulation of defecation. They also provide sensory innervation to the skin around the anus.
Clinical significance[edit | edit source]
Damage to the inferior anal nerves can result in Fecal incontinence, a condition characterized by the inability to control bowel movements. This can occur due to injury, surgery, or diseases such as Diabetes mellitus or Multiple sclerosis.
