Rugose corals will sometimes have dissepiments, which are curved plates connected to septa and tabulae.
Septa are subsequently formed at regular intervals along the hyphae to produce uninucleoid compartments, each of which develops into a spore, thus resulting in the formation of spore chains.
Septate junctions are unique to non-chordate invertebrate cell layers and have a characteristic ladder-like appearance whereby adjacent cells are connected by septa.
The lung epithelium is supported by a basal lamina that, in thin regions of the alveolar septa, is fused with the basal lamina of the alveolar epithelium and capillary endothelium.
Fresh chemicals on new septa were used for each weevil.
This is not surprising since disruption of all septa in an embryo would not be required to render the blastocoele permeable.
Internally, the pulmonary membrane of each lung is greatly folded with the alveoli separated by highly vascularized septa : ultrastructural observations were restricted to the alveoli.
The left component of the inferior bridging leaflet is anchored to the ventricular septa/ crest (arrowhead).
