| 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: | chemical treatment by injection |

| Definition: | Chemical treatment in which the chemical is injected into the zebrafish. |

| Name: | insulin |
|---|---|
| Synonyms: | |
| Definition: | A peptide hormone which consists of two polypeptide chains, A- and B- chains which are linked together by disulfide bonds. The amino acid sequence of insulin varies across species and certain segments of the molecule are highly conserved. In most species, the A chain consists of 21 amino acids and the B chain consists of 30 amino acids. In mammals, insulin is synthesised in the pancreas within the β cells whereas in certain species of fish, the insulin-producing tissue is uniquely located in separate structures called Brockmann bodies. |
