Abstract

Myenteric nervous plexus is from rare importance for function of gastrointestinal tract. It perform one regulatory level autonomic nervous system which is situated within wall of digestive tract wherefore is directly exposed effect pathogenetic factors from extern ambiance. Aim of these study is that itself within terminal part of large intestine (sigmoid colon and rectum) particulary inquest myentric nervous plexus as part of autonomic nervous system. That itself describe shape and arrangement of ganglion structures, as well as, shape and arrangement of ganglion cells of myenteric nervous plexus. Within our researches we use totally 60 tissue samples of human sigmoid colon and rectum. From anterior wall those part of large intestine was taken 30 samples, also and same number of samples towards parts of posterior wall. Proximately past getting samples was determine their volume by using picnometre. Afterwards are made preparations coloured by He, Cresyl - violet and AgNO methods. Tissue samples are sliced within step - shared series of incisions with thickness slice by 7µm and 3 thickness grade by 50µm. Stereologycal analysis was perform by test system M42 which is calibrated on enlarge objective 40x. During analysis was determined absolute volume of ganglion structures of myenteric plexus and absolute number of ganglion cells inside of ganglion structures. Structures of myenteric nervous plexus being shown on longitudinal cross - section of tissues as flat, irregular ramify structure explicitly limited from surrounding smooth muscles. Immanent is upward trend absolute volume of ganglion structures and absolute number of ganglion cells goes from sigmoid colon according to ampullar part of rectum. Variance on level of significance by p<0,05 are present only if itself compare absolute volume of ganglion structures and absolute number of ganglion cells of myenteric plexus ampullar part of rectum and uppermost part of sigmoid colon. Test correlation shows of being presence high statistic significant (p<0,001) correlation between absolute volume of ganglions and absolute number of ganglion cells of myenteric nervous plexus.
