There is spongy bone, also called trabecular or cancellous boneLess dense bone with a lattice-like structure. Also called spongy bone. , and compact bone, also called cortical boneDense, strong bone that surrounds trabecular bone tissue. Also called compact bone. (Figure 9.1 The Arrangement of Bone Tissues).t surrounds all trabecular tissue and is the only bone tissue in the shafts of long bones. Figure 9.2. The two basic tissue types of bones are trabecular and cortical. Trabecular (spongy) and cortical (compact) bone tissues differ in their microarchitecture and porosity.
