Pelvic model with pelvic floor muscles and genitals, female

Anatomically speaking, the model shows both the woman's pelvis, the muscles in the pelvic floor, the internal and external genitalia as well as the relationships of the urinary bladder with the urethra and the rectum.



The pelvis consists of the 3 building blocks, which are the 2 hip bones and the sacrum. The model also shows the 2 lower lumbar vertebrae. Overall, the model shows the following bones:



Os coxae (the 2 hip bones) of which both are composed


- Os ilium (iliac bone/hip bone)

- Os ischii (seat bone)

- Os pubis (pubic bone)



Us sacrum (sacrum) incl. os coccygis (coccyx)
4th and 5th lumbar vertebra (lumbar vertebra)


In the bone tissue, the most important details can be seen, such as large nodules. Smaller details such as the linea glutaea are omitted. As something special, the sacrum can be opened. It makes it possible to see the canalis sacralis as well as the Y-shaped canals in its lateral wall (where nerves run). Furthermore, some ligaments are seen. It is first and foremost equal. sacrospinal and lig. sacrotuberal.



The pelvic floor (also called the pelvic floor or diaphragma pelvis in Latin) consists of the following muscles, which are clearly visible:



- M. levator ani (consisting of m. pubococcygeus and m. iliococcygeus)

- M. coccygeus



Other muscles are also seen such as the ischiocavernosus muscle, the bulbospongiosus muscle and the obturator internus muscle.



The internal genitalia include the ovaries (ovaries), the fallopian tubes (tubae uterinae), the uterus (uterus) and the vagina (vagina), all of which are seen in the greatest detail. Anatomically, it is located in the small pelvis. They are seen in relation to the urinary bladder (vesica urinaria) with the urethra (urethra) and the rectum (rectum).



The external genitalia are shown with the largest and most important details, which anatomically are located in front of and below the symphysis.



Many of these organs function as a channel or a reservoir (e.g. the vagina and the urinary bladder), which is why they are seen in a pedagogical way with an air-filled cavity (cavity). Special areas are shown in an educational color - for example glans clitoridis in yellow and fimbriae in dark red.

The pelvis as a birth canal



Normally the following 3 connection lines are specified:



- Conjugata vera (normally measures 11 cm in the female pelvis)

- Diameter obliqua (usually measures 12.5 cm in the woman's pelvis)

- Diameter transversa (usually measures 13 cm in the woman's pelvis)



On this pelvis model, all 3 above connecting lines measure 11 cm. This is due, among other things, to the fact that the size of the model corresponds to a 14-year-old (as mentioned at the beginning of the description above).
