The backbone of Pterophyllum scalare.
In this chapter we analyze the vertebrae that make up the skeleton of the [I] Pterophyllum scalare [/ I].
If any bone that forms the skeleton of the fish has functions that fit into the set of their anatomy and that meet certain requirements of adaptation, the 29 vertebrae of the Scalar no longer a major part in understanding the more of how the inner world is made and the importance it plays in it. The group is full of vertebrae which we call column or spine.
As we will discover in this chapter and in fresh dissection presents some complex functions. This presents spine curved shape unlike a number of other species of fish.
When beginning the dissections and proceed to clean the different vertebrae, they would unravel some peculiarities of some of them significant elements that we analyze, and in some cases are those of our fish.
Far from presenting a uniform along the vertebrae that make up the Spine, different features appear, or groups as well as individually.
Numbered from the bones of the skull to the tail (of the 1st on the 29th), we can see with the naked eye as main difference that the set of vertebrae, the first 13 have only the "Espina Neural" (top of vertebra) is , while the remaining 15 have two spines developed, both the "Neural Spinal" as the "Thorn Hemal" (bottom of the vertebrae), vertebra 29 differs from the other in form and constitution.
The set of the first 13 vertebrae are called "Vertebrae abs" (single neural spine) except the 4th vertebra (differentiated training), the following 14 are called "Caudal vertebrae" (with both spines neural and hemal), and the last two vertebrae to form the 29 penultimate identifies them as "Vertebra preural" and the latter as "ural vertebra".
