What's a Pelvis Anyway
The Big Picture
What exactly is your pelvis? Is it where your belly button is? Is it part of
your tush? Or is it just where your private parts are? Actually, it’s all of it. Your
pelvis is a wonderful and mysterious place.
When you look at this picture of the pelvis, you can see that the big bones
come together to create a space, like a bowl. All the goodies in and around this
bowl are called organs (just like your heart is an organ).
Those pelvic bones protect and hold your organs in place. Getting to know
all the parts – the soft ones and the hard ones – can keep you “connected” to
your body throughout your life, instead of pretending it’s not even there – until,
that is, something goes wrong.
Try this: Make a frame with your hands across your belly button and just
below the zipper of your jeans. That’s your pelvic region.
In and Out
Welcome! We’re going to take you on a tour of your pelvic region – where
you are Queen!
Most of your pelvic parts are inside of you. Some of them are outside of
you, too. To the north you’ve got your intestines; to the south, well, you’ve got
some other wonderful stuff, all treasures.
By the end of this chapter, you’ll really know the geography of your pelvic
region and be proud to call it your own. Let’s see what’s going on down there. Be
sure to look at the map of your pelvis as we take our tour. Wear your hiking
boots; bring some water.
Protective Parts – Bones and Muscles and other Structures
Pelvic Bone, Pubic Bone, Coccyx, Pubic Symphesis, Pelvic Pyramid, Mons
The protective parts of your pelvis are like walls, barriers, castle moats,
and cushions, holding and protecting the organs inside them.
Let’s see what they do and where they are:
- Pelvic Bones Two large bones that kind of look like a butterfly – these are the ones that form the bowl. They hold your pelvic organs inside. You know the outside rim of these as your hip bones.Pubic Bones Two smaller bones, connected to your pelvic bones. They are found on the front side of the lowest part of your pelvic bone structure. If you lie on the floor you can feel them.
- Pubic Symphesis An interesting little section made of cartilage found firmly attached to your pubic bones.
- Coccyx (sounds like COX-ix) This crazy word is the proper name for your tailbone, the bone at the end of your spine. You don’t want to fall on your tailbone because it hurts! But, if you do fall, your coccyx protects organs inside your pelvis.
- Pelvic Pyramid Muscles On both sides of your lower spine and across your abdomen (AKA your belly, not to be confused with your actual stomach, an organ). You will learn much more about these very important muscles in upcoming chapters. They are responsible for so much! Everything from your posture and your strength to how you pee and poop. Woohoo! Betcha can’t wait to learn more.
- Mons Pubis (sounds like Monz Pyoobis) The is an external area, located on your front side just below your “bikini line”. The mons pubis is like a cushion the shape of an upside down triangle. Once you have reached puberty pubic hair will grow here. Your mons pubis helps make a fall on your pubic bones a little softer!
