| Name: | medial longitudinal fasciculus |
|---|---|
| Synonyms: | MLF |
| Definition: | The medial longitudinal fasciculus (MLF) is a pair of crossed fiber tracts (group of axons), that begin with in the nucleus of the MLF and run ventral to the rhombencephalic ventricle, towards the caudal end of the medulla oblongata. The dorsal portion of the MLF including the Mauthner axon continues into the spinal chord while the ventral portion of the MLF associates with other fiber systems in the funiculus ventralis prior to reaching the spinal chord. Throughout the most of its rhombencephalic extent the MLF is intersected by the ventral rhombencephalic commissure. |

| Name: | primary neuron |
|---|---|
| Synonyms: | |
| Definition: | Primary neurons are neurons develop shortly after gastrulation during early segmentation stages, between 10-12 hpf, before the neural tube is formed. Each neuron occurs in a stereotyped location along the neuraxis. Axons from these cells grow via a growth cone pioneering a stereotyped pathway. These axons form the pattern of the early nervous system. |
