Abstract

Ereksiyon sinir sistemi, damar sistemi, penis ve yardımcı oluşumlarının
kombine çalışması ile oluşmaktadır. Sinir uyarımları ile arterlerde
oluşan genişleme, venlerde gözlenen daralma (görüş birliği henüz
yoktur) ve trabekulalarda bulunan düz kaslardaki gevşeme ile
başlamaktadır. Ereksiyonun gevşemeden önceki son dönemi olan e«rijit
ereksiyon fazı ise çoğu araşlırıcıların fikrine göre iskiokavernöz
kaslarda meydana gelen kasılma, bir kısmına göre ise trabekulalarda
yeralan düz kasların kasılması ile oluşmaktadır.

Mechanısm Of Erectıon

Abstract

Erection occurs by the interaction of nervous system, vascular
system, penis and its auxillary elemeni$. In the first stage of erection,
neuronal impulses produce dilatation in the penile arteries, vas0constriction
in veins (but still there is no agreemeni) and relaxation in the trabecular smooth muşcles. Most of the authors describe that, contraction
in the ischiocrural muscles makes «rigid phase of erection»
which iş the previous stage before the flaccid phase. However, fewer
number of authors explaine this process with contraction ol trabecular
smooth muscles,
