Reflection on Group Work
The outlet of the pelvis is filled with soft tissue and the strong diaphragm of muscle being the most important. The main function of the pelvic floor are2 support the weight of the pelvic &abdominal organs.Afford voluntary control over micturition defeacation& flatulation Diminishes the size of the vagina&causes engorgement of the clitoris during intercourse.Influences movement of the fetus during the seconnstage of labour.The pelvic consists of2layersof muscle:superficial layer which is smaller then the deeplayer.with both conbined contribute the overall strength of the pelvicfloor & r likely2become damaged during vaginal delivery.Bulbocavernosus Thismuscle arises from the perineum,passes around the vagina&embed n the clitoris.function:causes erection of the clit&contraction of the vagind during intercourse.Ischiocavernosus:this muscle extends from the ischial tuberosities2 the clitoris.Function contributes to the formation of the urethral spincter&does not become damaged during childbirth.Transverse perineal muscle:this extends from the ischial tub2the perineum,the fibres also intermingle w the perineal body&the anal spincter.function provides additional support,however will always become damaged during CB.External anal spincter.This muscle surrounds the anal office&attaches 2the coccyx.Function closes the lumen of the anus&prevents fetal incontinence.Thedeepmusclelayer comprisedof3 pairs of muscles which r known as the levator ani muscles. Pubococcygeus M extends from the pubicbone surrounding the urethra,vagina&rectum attaches2the coccyx.function supports the lower third of the vagina&rectum controls the flow of urincontrols defaecation,contracts during orgasm,aidsCB.Illiococcygeus M extends from the inner aspect of the lilacbone,meet in the perineum&extends2the coccyx.function provides support.Ischiococcygeus M triangular sheet of M.arises from the ischial spines&pass2the lower sacrum&upper coccyx.Function stabilies&supports the sacroiliac joint&sacroccygeal
