APPENDIX 1 Parts List

John Sulston, John White


Appendix 1 provides a list of all terminally differentiated somatic cells, together with key blast cells (viz. embryonic founder cells and blast cells present at hatching).

First column: Functional name. This nomenclature is fairly arbitrary; its purpose is to allow cells to be classified by type. Note the use of appended symmetry operators (A, anterior; P, posterior; D, dorsal; V, ventral; L, left; R, right) to distinguish between equivalent cells in symmetrical groups.

Second column: Lineage name. This nomenclature formally summarizes the lineage by which the cell is derived from a key blast cell; it is described fully in Chapter 5.

Third column: Brief description. See appropriate chapters for more detail.

The Table following the Parts list provides nuclear counts.
