| Name: | macula saccule |
|---|---|
| Synonyms: | saccular macula |
| Definition: | Portion of tissue that is a patch of thickened, pseudostratified epithelium in the inner ear, consisting of regular arrays of sensory hair cells interspersed with supporting cells. The macula saccule senses linear acceleration and gravity. In juveniles the macula saccule is oriented vertically in a plane running along the anterioposterior body axis. It covers the medial wall of the saccule along most of its length. |

| Name: | has fewer parts of type |
|---|---|
| Synonyms: | decreased number of, has decreased number of, has fewer physical parts of type |
| Definition: | The bearer of this quality has_part < n AND has_part > 0 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. |

| Name: | hair cell |
|---|---|
| Synonyms: | hair cells |
| Definition: | Hair cell is a mechanoreceptor cell that is sensitive to movement of the hair-like projections (stereocilia and kinocilia) which relay the information centrally in the nervous system. |
