The next set of vertebrae that we can continue gathering to have a constitutively Similarly, (14, 15, 16, 17 and 18).
This group of vertebrae in his spine Hemal present a formation anteriorly to which we have called "Hemal Wall". It is a bony lamina is on the central axis of the spine protruding from it.
In this group of vertebrae plus Hemal Spine vertebrae 14 and 15 have parapophysis. The parapophysis disappear from the fifteenth vertebra.
At present this work to begin on the vertebrae, mention was made to the role of the channel in Neural spines in support of the spinal cord. In the case of vertebrae hemal, its channel is traversed by the aorta.
In relation to size of both thorns, the Espina Neural start decreasing as we proceed with the number of vertebra. With respect to the Espina Hemal, this first vertebra is the of greater size.
With respect to Canal Neural, will continue few fluctuations but with tendency to follow decreasing. The Canal Hemal, also will have fluctuations about its size with slight differences with tendency to their decline.
