HUMAN PELVIC FLOOR DYNAMIC STABILIZATION MECHANISM STRUCTURES – A SLING ARCHITECTURE DEVELOPMENT

Abstract

The bipedalism that developed in anthropogenesis process radically changed the functional basis in human pelvic floor muscles. In quadrupedals the main function of levator ani muscle is the movement of the tail associated with the flexion of tailbones and tail tucking towards the trunk; in humans it is the closure of the pelvic cavity and organs support, as well as the regulation of urine, feces, seminal fluid passage in men, and labor activity in women. Analysis of dynamic protection mechanisms in the area of pelvic outlet will allow understanding pelvic diaphragm and perineal muscles morphofunctional aspects during physiological processes (urination, defecation, labor, etc.); but also it will form the knowledge about possible causes of pelvic floor insufficiency, urinary and fecal incontinence, sexual dysfunction, and pelvic organ prolapse.

Objective. According to literature data review and own research, the objective is to develop a new concept about pelvic floor and perineal muscles activity, pelvic organs dynamic support, and regulation mechanisms in metabolic products excretion and labor regulation.

Results. We developed conceptual schemes of pelvic floor and perineal skeletal muscles sling shape architecture based on literature data analysis. We describe five skeletal muscle sling structures in men, and six in women. This theory of sling structures in pelvic floor and perineum may allow expanding the approach to the pathogenesis and treatment of pelvic floor dysfunctions, perineal muscle injuries, urinary and fecal incontinence, as well as pelvic organ prolapse.
