| Name: | telencephalon |
|---|---|
| Synonyms: | |
| Definition: | The anterior and dorsal forebrain neuromere. In ray-finned fishes and most pronounced in teleosts the roof plate of the embryonic telencephalon extends laterally with the effect that the paired alar plates forming the hemispheric walls roll out lateroventrally in a process called eversion. This is unlike the development in other vertebrate groups. From Neuroanatomy of the Zebrafish Brain. |

| Name: | astrocyte |
|---|---|
| Synonyms: | astrocytes |
| Definition: | A class of large neuroglial (macroglial) cells in the central nervous system - the largest and most numerous neuroglial cells in the brain and spinal cord. Astrocytes (from 'star' cells) are irregularly shaped with many long processes, including those with 'end feet' which form the glial (limiting) membrane and directly and indirectly contribute to the blood-brain barrier. They regulate the extracellular ionic and chemical environment, and 'reactive astrocytes' (along with microglia) respond to injury. |
