| Synonyms: | loss of |
| Definition: | The bearer of this quality has_part < n of the indicated entity type, where n is the normal amount for a comparable organism. Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type. |

| Name: | intervillus pockets |

| Synonyms: | intestinal crypt |
| Definition: | A portion of tissue formed between the base of the intestinal villi that is part of the intestinal epithelium where intestinal stem cells are located. In the intestine no crypts are present, but, the regions between the villi, the intervillus pockets, have a crypt-like function. Cells are produced in the intervillus pockets and shed from the villus tips. |
