Female Pelvic Muscles and Organs

Quick Answer: The female pelvic muscles and organs model is an anatomical model of the adult female pelvis that shows the pelvic floor muscles together with the organs they support. It is used in nursing, midwifery and physiotherapy teaching to explain continence, childbirth and pelvic organ support.

The Pelvic Floor and the Organs It Supports

The pelvic floor is a sling of muscle stretched across the outlet of the bony pelvis. Its main part, the levator ani, is made up of the pubococcygeus, puborectalis and iliococcygeus, with the coccygeus behind them. A model of the pelvic muscles and organs lets students see these muscles in place rather than as a flat diagram, along with the three openings that pass through the floor: the urethra, the vagina and the anal canal.

The same model places the bladder at the front, the uterus and vagina in the middle and the rectum at the back, all resting on the muscle layer. Seeing that arrangement explains why weakness of the pelvic floor can lead to leakage of urine or to prolapse of the bladder, uterus or rectum into the vagina, and why the puborectalis sling matters for faecal continence.

In midwifery teaching the model is used to show how the pelvic floor stretches during the second stage of labour and where the perineal body lies, the point at which tears and episiotomies are described. The exact muscles and organs shown, and whether any parts come out, depend on the model and should be confirmed before ordering.

Specifications

Applications

• Teaching pelvic floor anatomy and its role in urinary and faecal continence
• Explaining the types of pelvic organ prolapse to nursing and physiotherapy students
• Showing the perineal body and the stretch of the pelvic floor during childbirth
• Patient education on pelvic floor muscle exercises, pointing to the muscles being trained

Care & Handling

• Move the pelvic muscles and organs model with both hands under its base, keeping fingers clear of the thin muscle edges.
• Clean painted surfaces with a soft damp cloth; alcohol and solvents can strip the colour coding.
• Cover the model when not in use to keep dust out of the deep recesses of the pelvis.

Why Choose LabEquip

Midwifery schools, physiotherapy departments and nursing colleges buy this model when a plain bony pelvis cannot show what supports the organs. LabEquip also supplies the female half pelvis section model, and both are part of its biology lab products. Send your course requirements through the contact page.

Frequently Asked Questions

Which muscles make up the pelvic floor?

The main group is the levator ani, formed by the pubococcygeus, puborectalis and iliococcygeus, together with the coccygeus at the back. They form a bowl-shaped sheet across the pelvic outlet.

What does the pelvic floor do?

It supports the bladder, uterus and bowel, helps keep the urethral and anal openings closed until voiding, and relaxes and stretches during childbirth.

How does the model help explain prolapse?

It shows the organs sitting on the muscle layer. When that support weakens, students can see how the bladder, uterus or rectum could descend into the vagina, which are the main forms of prolapse.

What is the perineal body?

It is a fibromuscular node between the vagina and the anus where several pelvic floor muscles attach. It matters in childbirth because perineal tears and episiotomies involve this area.

Can the model be used in patient education?

Yes. Physiotherapists and nurses use pelvic models to show patients which muscles pelvic floor exercises train, which often makes the exercises easier to understand.

How is this model different from a half pelvis model?

A half pelvis model is cut down the midline to show the organs in section. This model focuses on the muscular floor and how the organs rest on it, so the two are often used together.
