| Name: | Mauthner neuron |
|---|---|
| Synonyms: | |
| Definition: | Is a hindbrain interneuron. Giant reticulospinal neurons possessing thick crossed axons and positioned dorsally in the hindbrain tegmentum at the level of entrance of the eighth cranial nerve. The Mauthner neuron is paired. The M-cell has two large invariant dendrites: The lateral dendrite terminates in the sensory neuropil of the acoustico-lateral area, and the ventral dendrite terminates in the neuropil of the motor tegmentum. Fine dendrites are present, and mostly arise from three regions; from the terminus of each major dendrite and from the ventral surface of the perikaryon. |

| Name: | gap junction assembly |
|---|---|
| Synonyms: | |
| Definition: | Assembly of gap junctions, which are found in most animal tissues, and serve as direct connections between the cytoplasms of adjacent cells. They provide open channels through the plasma membrane, allowing ions and small molecules (less than approximately a thousand daltons) to diffuse freely between neighboring cells, but preventing the passage of proteins and nucleic acids. |
