To study the Thurston spine Pg ⊆ Tg, we construct a Teichmüller curve V ⊆ Tg. Then we characterize V ∩ Pg. More specifically, we show it is a trivalent tree and is an equivariant deformation retract of V. Moreover, by our construction, a lot of essential loops in the Thurston spine, both reducible and pseudo-Anosov, are obtained.
