| Name: | neuromast hair cell |
|---|---|
| Synonyms: | neuromast hair cells |
| Definition: | Neuromast hair cell is a hair cell that acts as a sensory receptor of the neuromast; it is morphologically polarized as a result of the relative position of the single kinocilium and the clusters of stereocilia on its apical surface. |

| Name: | cytoskeleton of presynaptic active zone |
|---|---|
| Synonyms: | active zone cytomatrix, CAZ, pre-synaptic cytoskeletal matrix assembled at active zones, pre-synaptic dense body, pre-synaptic ribbon, presynaptic cytomatrix assembled at active zones, presynaptic cytoskeletal matrix, presynaptic cytoskeletal matrix assembled at active zones, presynaptic dense body, presynaptic ribbon, ribbon, synaptic ribbon, T-bar, T-bar ribbon |
| Definition: | The specialized cytoskeletal matrix of the presynaptic active zone. It has specialized functions in organizing synaptic events such as immobilisation or translocation of synaptic vesicles, and assembling active zone components. It is believed to form a molecular scaffold that organizes neurotransmitter release sites. |
