*Tail notochord and somites form through regression of the tail bud.

**'''No endoderm exists in the tail bud.'''
**'''No endoderm exists in the tail bud.'''
*Production of the tail bud is called '''secondary gastrulation''', production of the primitve streak, node and notochord is called '''primary gastrulation'''.
*Without the tail bud, the notochord would run out of cells before the hindlimb could be made.

*In animals that have tails, cells at an additional site undergo gastrulation.
