Human Pelvis, 2 Parts, Female

Quick Answer: The human pelvis, 2 parts, female, is a replica of the adult female pelvis that separates into two pieces, so students can study both its outer form and what lies within. This 2 part female pelvis model is used in nursing, midwifery and biology lessons on the pelvic girdle and on how the female pelvis is adapted for childbirth.

What Two Parts Add to a Pelvis Model

Pelvis models are made either as a single fixed piece or as sections that come apart. A two-part model can usually be separated along a plane, often the midline, so that the inner surface of the pelvis and any organs modelled inside are opened to view and then closed again. The title does not say where this model divides or whether it includes pelvic organs as well as bone, so ask for the parts list before ordering if your lessons depend on either.

The bony pelvis is formed by the two hip bones, each made of ilium, ischium and pubis fused together, joined in front at the pubic symphysis and behind to the sacrum at the sacroiliac joints, with the coccyx below. The female pelvis differs from the male in ways that favour childbirth: the inlet is wider and more oval, the subpubic angle is wider, the ischial spines project less and the sacrum is shorter and less curved.

Opening the model lets those differences be seen from inside, for example the roomier true pelvis below the pelvic brim that the fetal head must pass through. For the female pelvic organs in a fixed median section, see the human female half pelvis; the human pelvis, female listed in this range is the other option.

Care & Handling

• Separate and rejoin the two parts of the pelvis model gently along their fitting edges; forcing the join wears the locating pins.
• Store the parts assembled, or together in one box, so they are not mixed up with pieces of other models.
• Clean with a slightly damp cloth and dry, paying attention to the inner surfaces where dust collects.

Applications

• Comparing female and male pelvic features in anatomy and forensic science lessons
• Showing midwifery students the pelvic brim, true pelvis and outlet that the fetal head passes through
• Nursing lessons on the pubic symphysis and the sacroiliac joints
• Small-group work in which each student opens the model to see the inner surfaces

Why Choose LabEquip

Midwifery and nursing tutors often choose a pelvis that comes apart because a group can look inside it without a second model. LabEquip carries this model in its biology lab products and can confirm what the two parts contain through the contact page.

Frequently Asked Questions

What does 2 parts mean for a pelvis model?

It means the model separates into two pieces that fit back together. Such pieces commonly divide along the midline or open to show internal structures; the listing does not say which applies here, so the parts list is the thing to request.

How does the female pelvis differ from the male pelvis?

The female pelvis is generally lighter, with a wider oval inlet, a wider subpubic angle, less prominent ischial spines and a shorter, flatter sacrum. These features give the fetal head more room during birth. The male pelvis is heavier and narrower, with a heart-shaped inlet.

What is the pelvic brim?

The pelvic brim is the rim of the pelvic inlet, running from the sacral promontory along the arcuate lines of the ilia to the top of the pubic symphysis. It divides the false pelvis above from the true pelvis below.

Which bones make up each hip bone?

Each hip bone is formed by the ilium, ischium and pubis, which fuse at the acetabulum, the socket for the head of the femur, by early adulthood.

Why do midwives study the bony pelvis?

The fetal head has to pass through the inlet, cavity and outlet of the pelvis during birth. Knowing the shape and landmarks helps midwives understand how the baby turns and descends in labour.

Can the model be used for a male versus female comparison?

Yes, although a male pelvis is needed alongside it for a direct comparison. With the female model alone, teachers can point out each female feature and compare it with diagrams or a skeleton.
