The male reproductive system and pelvic floor muscle - image description

A cross-sectional illustration showing the positions of the male pelvic organs including the bladder, urethra, prostate gland, rectum and anus. The image is from the side with a man facing to the left.

On the left of the image there is a bone called the pubic bone. This is at the front of the body beneath the bladder and above the root of the penis. At the back of the body are the bones that make up the spine. A layer of muscles called the pelvic floor muscles are attached to the pubic bone at the front of the body and go to the last bone in the spine at the back of the body. This looks a bit like curved hammock shape.

The bladder is in the centre of the image. A tube called the urethra runs from the bottom of the bladder through the prostate gland directly beneath the bladder, through the pelvic floor muscle and then through the penis to the opening at the tip of the penis.

Behind the bladder and prostate gland is the rectum. The rectum narrows at its lower end as it passes through the pelvic floor muscle. The rectum then joins to the anus where the bowel opens to outside the body.
