I have just looked at your other question. I can see your puzzlement. The Arabic text uses two words when only one word will suffice. All of these things are called "anatomical models," as you will see online. There is no telling why the Arabic copywriters chose two different words. They probably were not sure which word would be most accessible to the target consumer, so they used both. This is a common practice. The text may even be a translation, so you could well be doing a back-translation.
