The first step in the process is the formation of bone spicules which eventually fuse with each other and become trabeculae. The periosteum is formed and bone growth continues at the surface of trabeculae. Much like spicules, the increasing growth of trabeculae result in interconnection and this network is called woven bone.
Inside of a bone showing the trabecular structure A typical carcinoid tumor of the lung showing a trabecular pattern of elongated groups of cells.. A trabecula (pl.: trabeculae, from Latin for 'small beam') is a small, often microscopic, tissue element in the form of a small beam, strut or rod that supports or anchors a framework of parts within a body or organ.
The meshing of many spicules serves as the sponge's skeleton and thus it provides structural support and potentially defense against predators. [1] Sponge spicules are made of calcium carbonate or silica. Large spicules visible to the naked eye are referred to as megascleres or macroscleres, while smaller, microscopic ones are termed microscleres.
The wedding cake turned out surprisingly well, with the layers cooked just a bit unevenly As a hyper-realistic cake artist, Jonny Manganello has baked a lot of cakes. But baking a wedding cake ...
Whether it’s layer cakes, sponge cake, or pound cake, we’ve never had a cake we don’t like. When mid-afternoon hunger strikes and we’re ready for tea time or a coffee break, we can’t ...
While the spicules in most species are triradiate (with three points in a single plane), some species may possess two- or four-pointed spicules. [4] [5] Unlike other sponges, calcareans lack microscleres, tiny spicules which reinforce the flesh. In addition, their spicules develop from the outside-in, mineralizing within a hollow organic sheath ...
Cake is frosted or iced or covered in fondant or ganache. Cheesecake has none of those things (unless it’s a super stunning layered cheesecake, which actually sounds amazing). Plus, it has a crust.
In sponges they secrete calcareous or siliceous spicules which are found in the mesohyl layer of sponges. The sclerocytes produce spicules via formation of a cellular triad. The triad of cells then undergo mitosis, creating six sclerocytes. In pairs, the sclerocytes secrete the minerals which create the spicules. [1]
