Quick Answer: The human female pelvis (4 parts) PVC plastic is a model of the female pelvis that separates into four pieces and is made of PVC. This 4 part female pelvis model serves nursing, midwifery and anatomy teaching by showing the pelvic organs and how they sit within the bony pelvis.
What Four Parts Allow
Pelvis models are sold as one piece, as halves, or with parts that lift out. Four parts suggests that some organs or sections can be removed, so the teacher can first show the pelvis with everything in place and then take pieces away to reveal what lies deeper, for example lifting out part of the uterus or bladder to show the structures behind. The title does not list the four parts, so the exact contents should be confirmed.
Removable organs make the supporting structures easier to teach. The broad ligament is a sheet of peritoneum draped over the uterus and uterine tubes; the round ligament runs from the side of the uterus forwards to the inguinal canal; and the ovary hangs from the back of the broad ligament, tethered to the uterus by its own ligament. The ovarian vessels reach the ovary through the suspensory ligament from high on the posterior abdominal wall, because the ovary develops near the kidneys and descends; for the same reason, ovarian lymph drains to nodes beside the aorta rather than to pelvic nodes.
PVC is named as the material. It is a durable plastic that holds moulded detail and can be wiped clean, which suits a model that is taken apart and reassembled many times. For bony obstetric landmarks alone, the two-part female pelvis model is listed separately.

Applications
- Anatomy teaching of the female pelvic organs, ligaments and peritoneum
- Midwifery and nursing lessons on the organs surrounding the birth canal
- Explaining the ligaments and blood supply of the uterus and ovaries to nursing and medical students
- Patient education on gynaecological procedures, with parts removed one at a time
Care & Handling
- Return all four parts of the 4 part female pelvis model to their places after class; a missing piece makes the model hard to use for the next group.
- Fit parts gently and do not force pegs or clips, which are the usual wear points of take-apart models.
- Wipe with mild soap solution and keep the model away from heat, which can distort PVC.
Why Choose LabEquip
Nursing, midwifery and anatomy departments buy take-apart pelvis models so one model can serve both introductory and more detailed lessons. It is in LabEquip’s biology lab products; confirm the four parts through the contact page.
Frequently Asked Questions
What does ‘4 parts’ tell a buyer?
That the model comes apart into four pieces, typically a base pelvis with organs or sections that lift out. Take-apart models let the teacher reveal deeper structures in stages. The list of parts differs from model to model.
What is the broad ligament?
It is a double fold of peritoneum that hangs over the uterus and uterine tubes like a sheet and stretches to the side walls of the pelvis. It carries the blood vessels, nerves and lymphatics of the uterus and ovaries between its layers.
Why do the ovarian vessels come from so high up?
The ovaries develop on the back wall of the abdomen near the kidneys and descend into the pelvis before birth, bringing their blood supply with them. The ovarian arteries therefore arise from the abdominal aorta, and ovarian lymph drains to nodes beside the aorta.
Where is the ovary attached?
The ovary is held to the back of the broad ligament by a short fold called the mesovarium, to the uterus by the ovarian ligament and to the pelvic wall by the suspensory ligament, which carries the ovarian vessels.
How is this model different from a half pelvis?
A half pelvis model is a fixed section through the midline. A take-apart model lets parts be removed and replaced, so the same model can show surface relations first and deeper structures afterwards.
Which courses use this model?
Nursing, midwifery and medical anatomy courses, and physiotherapy programmes that cover women’s health. Senior biology classes also use female pelvis models for reproductive anatomy.
