Bony Pelvis

The bony pelvis without any of the muscles or organs showing.

Full Pelvic Floor with External Genitalia Clinical View

This picture is looking at the pelvic floor muscles from the bottom up. You can see the many different pelvic muscles and how they are all layered in the bottom of our pelvis.

Bladder and Urethra

Here is the bladder, urethra, and the two ureter tubes that connect to the kidneys. The bladder is surrounded by a muscle that we cannot control, called the detrusor muscle. The urethra is also surrounded by a small broad muscle that is part of our pelvic floor muscle group, called the compressor urethrae.

Compressor Urethrae

This picture shows the compressor urethrae muscle from looking at the bottom. This muscle helps compress and flatten the urethra when we try to hold back our urine.

Female Reproductive Tract

This picture represents the vagina, cervix, uterus, fallopian tubes, and ovaries, all contained in the pelvis.

Pubococcygeus Muscle

This picture is highlighting the pubococcygeus muscle, also known as the love muscle for its function of closing the vaginal opening. Dysfunction here can cause pain during intercourse.

Pelvis, Spine, and Muscles

This picture shows many of the hip and pelvic muscles that all undergo a lot of strain during childbearing.

Superficial Transverse Perineal

The muscle highlighted in this picture is called superficial transverse perineal and is often, cut or torn during vaginal births. This can make the muscle very painful during intercourse and sitting.

Pelvic Contents

This picture shows the pelvic organs, the bladder, uterus, and rectum/bowels.

Pelvic Floor Muscles, Superior View

Here is the pelvis with all of the pelvic muscles intact.

Pelvis with External Sphincters, Clinical View

Here is a bottom view of the pelvic floor muscles, you can see the external anal sphincter here that help control bowels. These muscles can also go into spasm creating rectal discomfort, difficulty with control and/or difficulty passing bowel movements.

Coccygeus Muscle

This picture highlights the coccygeus muscle. If this muscle is in spasm or is tight it can pull the coccyx bone forward into the rectum causing difficulty for stool passage, pain with bowel movements or tailbone pain with sitting. This muscle can often become spastic with tailbone injuries, or from fractures of the tailbone during childbirth.
