The video below shows how to describe a part of the human body -- a female reproductive organ. It shows how to describe and identify parts of the human female reproductive organ, using classifiers (mostly BPCL), and reference points.
After identifying the ovaries, the signer begins with the classifier for the ovaries, using both hands and indicating the location of the body. Then she establishes the spatial reference for the ovaries in neutral space with the same classifier.
Then, she uses another classifier for the fallopian tubes and index-tapping it with raised eyebrows. After tapping, the signer fingerspells the term fallopian tube for it.
With the previous identification of the ovaries and the fallopian tubes, the signer uses the classifiers only to establish these references once again before she goes on with the next classifier for "endometrium".
After signing the classifier for "endometrium", the signer identifies it by index-tapping it and then fingerspelling the term for it (not shown in this video clip).
After signing the classifier for "endometrium", she uses the classifier for "cervix" and identifies it by index-tapping it. Then, she would spell the word "cervix" (not shown in this video clip).
If you identify all parts of the organs, you don't need to repeat the classifiers all the way from the ovaries. You can continue from one part to the next part by using the last reference and then moving onto the next reference.
