What is the pelvic floor?
The pelvic floor is a collection of muscles that support the organs that exist in our abdominal cavity. These organs in the case of men are the bladder and intestines and in women, the bladder, intestines and uterus.
This set of muscles is not totally continuous, having small holes that allow the passage of channels that correspond to the urethra, the anus, and in women, also to the vagina.
The muscles around these orifices are tightly connected to keep these passages closed, with the help of extra muscle around the urethra and anus, which are the urethral sfi and the anal sfi.
What is the function of these muscles?
The pelvic floor muscles provide support for the abdominal organs, while the sphincters allow us conscious control over the bladder and bowel, enabling control over the excretion of urine, feces, and flatulence (gas).
Thus, when we contract the pelvic floor muscles the internal organs are lifted and the sphincters tighten the openings of the vagina, anus, and urethra. When we relax these muscles we allow urine and feces to pass.
The pelvic floor muscles also play a very important role in the sexual function of both sexes.
In women, voluntary contractions (compression) of the pelvic floor play an important role in sexual sensation and arousal, and also support the fetus during pregnancy and aid in labor.
In men, they are important in erectile function and ejaculation.
These muscles also partner with the abdominal and back muscles in stabilizing and supporting the spine.
