| Name: | Rohon-Beard neuron |
|---|---|
| Synonyms: | RB neuron, Rohon-Beard cell, Rohon-Beard neurons |
| Definition: | Primary sensory neurons with cell bodies located in the dorsal spinal cord, that innervate the integument of the trunk and tail at early larval stages. The cutaneous axons of Rohon-Beard neurons display a broad spectrum of peripheral axon branching patterns. Most Rohon-Beard neurons undergo apoptosis by 5dpf. |

| Name: | central nervous system myelination |
|---|---|
| Synonyms: | myelination in central nervous system |
| Definition: | The process in which neuronal axons and dendrites become coated with a segmented lipid-rich sheath (myelin) to enable faster and more energetically efficient conduction of electrical impulses. The sheath is formed by the cell membranes of oligodendrocytes in the central nervous system. Adjacent myelin segments are separated by a non-myelinated stretch of axon called a node of Ranvier. |
