The synsacrum is
a unit formed by the fusion of the posterior thoracic, lumbar, and sacral vertebrae
. Fusions of these bones make birds sturdy and indirectly lighter by decreasing the number of muscles necessary to control individual vertebrae.

What features strengthen a bird’s bones?

What is innominate bone?

, providing critical control surfaces, especially during takeoff and landing.
Why are bird bones fused and are lightweight?
The fusion of bones makes the
bird’s skeleton both lightweight and sturdy
. … The thoracic (chest area) vertebrae and vertebrae other neck vertebrae are fused to keep the bird’s trunk stiff. Because of this rigidity, the backbone provides the strong support of the back and wings the bird needs during flight.
