This spongy bone tissue is made up of tiny cross-hatching supports called trabeculae that help the bone resist stress.

这种海绵状骨组织由微小的交叉影线支撑物组成，称为小梁，帮助骨骼抵御压力。

Spongy bone tissue is typically found in the heads of long bones and in the inner layer of flat bones like the sternum.

海绵状骨组织通常存在于长骨的头部和胸骨等扁平骨骼的内层。
