Internal anal sphincter: Clinical perspective.
OBJECTIVE To summarise current knowledge of Internal anal sphincter.

متن کاملInternal Anal Sphincter Tone in Humans
39 The extracellular signal which triggers activation of rho-associated kinase (RhoA/ROCK), the major 40 molecular determinant of basal internal anal sphincter (IAS) smooth muscle tone in humans, is not 41 known. Using human IAS tissues, the presence of the biosynthetic machineries for Ang II, TXA2 and 42 PGF2α were identified. These end products of the renin-angiotensin system (Ang II) and ara...

It is only by studying the pathology of the area that it is...
