Human Female Pelvis Model

Human Pelvis, Female

Morphological Fidelity: Precision-cast from durable, high-density PVC to replicate natural bone texture, featuring identifiable landmarks such as the iliac crests, ischial spines, and the pubic symphysis.

Structural Articulation: Features a semi-flexible assembly of the fourth and fifth lumbar vertebrae and the sacroiliac joints, allowing for realistic demonstrations of pelvic tilt and skeletal orientation.

Quick Answer: The human pelvis, female, is a replica of the adult female pelvic girdle, the hip bones, sacrum and coccyx, used to teach obstetric landmarks and the dimensions of the birth canal. Midwifery, nursing and anatomy students use a female pelvis model to understand how the shape of the pelvis guides a baby through labour.

The Female Pelvis in Obstetric Teaching

Midwifery courses treat the pelvis as a canal with three levels: the inlet at the pelvic brim, the curved cavity, and the outlet, framed by the subpubic arch in front, the ischial tuberosities at the sides and the coccyx behind. Each level has a longest and a shortest diameter, and the fetal head turns as it descends so that its own longest dimension meets the widest space available. A model makes this rotation far easier to follow than a flat diagram.

Key landmarks are the sacral promontory at the back of the inlet, the ischial spines that project into the cavity and serve as the reference for the station of the presenting part, and the subpubic arch at the front of the outlet. The obstetric conjugate, from the sacral promontory to the nearest point on the back of the pubic symphysis, is the narrowest front-to-back diameter the head must negotiate.

The listing names a female pelvis but does not say whether it is bone only or also shows organs in section, as some pelvis models do, so the exact form is worth confirming. A version that separates into two pieces is listed as the human pelvis, 2 parts, female.

Care & Handling

Put the female pelvis model on a padded surface when passing a doll through it, so repeated demonstrations do not chip the pubic arch.
Avoid carrying it by the coccyx or the ischial spines, which are its thinnest projections.
Wipe with a cloth dampened in mild soapy water, then dry thoroughly.

Why Choose LabEquip

Midwifery schools, nursing colleges and obstetric training units buy a female pelvis for repeated hands-on demonstrations of labour. The model is part of LabEquip’s biology lab products range; ask through the LabEquip contact page whether it is bone-only or sectioned.

Frequently Asked Questions

What is a gynaecoid pelvis?

It is the typical female pelvis shape, with a rounded inlet, a roomy cavity and a wide subpubic arch, and it is considered the most favourable shape for vaginal birth. The other classic types are android, anthropoid and platypelloid.

What is the obstetric conjugate?

It is the shortest distance between the sacral promontory and the back of the pubic symphysis. As the narrowest front-to-back space at the inlet, it limits how the fetal head can enter the pelvis.

Why are the ischial spines important in labour?

They project into the pelvic cavity and are used as a reference point. The level of the baby’s head above or below the spines, called station, tells midwives how far the head has descended.

What are the inlet, cavity and outlet?

The inlet is the upper opening at the pelvic brim, the cavity is the curved space below it, and the outlet is the lower opening, framed by the pubic arch, the two ischial tuberosities and the tip of the coccyx. The baby passes through all three in turn.

Can a doll or fetal skull be passed through this model?

That is a common way pelvis models are used in midwifery teaching, but it needs a pelvis at natural size. If demonstrating the mechanism of labour is the main purpose, confirm the scale of this model when you enquire.

How does this differ from the two-part female pelvis?

The two-part model separates into pieces to show its inner surfaces. This listing is named simply as a female pelvis, which suits whole-pelvis demonstrations such as identifying diameters and following the baby’s path.
