The supporting alveolar bone consists of both cortical bone and trabecular bone. The increased pressure is caused by trabecular meshwork blockage. The subcapsular sinus drains into trabecular sinuses and finally into medullary sinuses. Trabeculectomy is a guarded filtering procedure that removes of part of the trabecular meshwork. A trabeculoplasty is a modification of the trabecular meshwork. The greatest resistance to aqueous flow is provided by the trabecular meshwork (esp. In people with narrow angles, this can uncover the trabecular meshwork. This new lamellar bone is in the form of trabecular bone. High porosity makes trabecular bone compliant and large variations in architecture leads to high heterogeneity. The arterial bulb forms the trabecular portion of the right ventricle. The process substitutes the trabecular bone with compact bone. For the skull development component, see trabecular cartilage. Larger animals did not show a significantly larger mass per unit volume of trabecular bone. Because of the microstructual directionality, the mechanical properties of trabecular bone is highly an-isotropic. As mentioned above, the mechanical properties of trabecular bone are very sensitive to apparent density.
