Uberon definition : The hyaline cartilaginous structures that support the bronchi, present as irregular
rings in the larger bronchi (and not as regular as in the trachea), and as small plates
and islands in the smaller bronchi; as the branching continues through the bronchial
tree, the amount of hyaline cartilage in the walls decreases until it is absent in
the smallest bronchioles[MP].;
