| Name: | basal communicating artery |
|---|---|
| Synonyms: | BCA |
| Definition: | Artery that extends horizontally across the brain midline which is fed by the caudal division of the internal carotid artery. Three pairs of central arteries extend from the basal communicating artery (BCA), the anterior, middle and posterior mesencephalic central arteries. The BCA does not correspond to the anterior communicating artery of the mammalian circle of Willis. The BCA is unpaired. |

| Name: | lacks parts or has fewer parts of type |
|---|---|
| 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. |
