Aim - to analyze and summarize the literature data of levator ani muscle, using the terminological approach. Materials and methods. We used literature in anatomy, biology with levator ani muscle description included Medline/Pubmed resources guide. Results. We found 18 terms determined levator ani muscle components in literature. The terms were used to describe diseases, perineal muscles, fascia and pelvic ligaments associated with urinary and fecal incontinence, traumatic injuries during labor in women, operative access to pelvic organs in men with surgical interventions for radical prostatectomy and rectum extirpation. We illustrated schematically levator ani muscle in men and women, supplementing the study by dissecting the perineal region in 3 men and 2 women. The terms defining the components of levator ani muscle in women are following: m. puboperinealis, m. pubovaginalis, m. puboanalis - united in m. pubovisceralis; m. pubococcygeus, m. iliococcygeus. In men, levatorani muscle is represented by the following components: m. puboprostaticus (m. levator prostatae), m. puboperinealis, m. puboanalis, m. puborectalis, m. pubococcygeus, m. iliococcygeus.

Aim - to study the structure of levator ani muscle in men and women of the first and second adult periods and elder group according to CT scan. Materials and methods. Data from CT scans of 40 patients aged 20 to 70 years were used. In the "Autoplan" system, in the semi-automatic mode, threedimensional models of levator ani muscle were created. Results. Three-dimensional models of levator ani muscle were created and described: for young women and men of all ages, a keel-shaped and funnel-shaped levator ani muscle forms; and for women of advanced age - horseshoe form.
