In the vertebrate spinal column, each vertebra is an irregular bone with a complex structure composed of bone and some hyaline cartilage, the proportions of which vary according to the segment of the backbone and the species of vertebrate.
The basic configuration of a vertebra varies; the large part is the body, and the central part is the centrum. The upper and lower surfaces of the vertebra body give attachment to the intervertebral discs. The posterior part of a vertebra forms a vertebral arch, in eleven parts, consisting of two pedicles, two laminae, and seven processes. The laminae give attachment to the ligamenta flava (ligaments of the spine). There are vertebral notches formed from the shape of the pedicles, which form the intervertebral foramina when the vertebrae articulate. These foramina are the entry and exit conducts for the spinal nerves. The body of the vertebra and the vertebral arch form the vertebral foramen, the larger, central opening that accommodates the spinal canal, which encloses and protects the spinal cord.
Vertebra is a framework that aims to simplify writing applications in The Cloud written by Engine Yard.
It was released under the GNU Lesser General Public License 3 at the end of 2008.
Vertebra is written in a combination of Ruby and Erlang.
It has been characterized as a Service-Oriented-Architecture for the cloud, an application deployment platform, and an evolution in the architecture for cloud computing. For its part, Engine Yard simply classifies it as "A Platform for the Cloud."
Vertebra may refer to:
Under the indefensible weight of the sky
The theatre of loss displays three coffins
Four stiff bodies in dark corners
Empty cradles rock in silence
Broken mirrors reflect infinite realities
No reality is certain
A violet sun shines with halogen reflections
For sleepers with inflated venters
Under the undefensible weight of the sky
Thousands of waves bring unknown voices
Thousands of voices bring certain mirrors
Lunar tongues relish amniotic rainbows
Infinite days perish in amniotic fluids
The choir of the dead
Recites its three rosaries
The crown is like a noose
The seventh grain is a vertebra
Worms swarm in twisted tongues
Blood from the ears and tears in the hands
Sperm in heaven for crawling angels
Sperm in heaven for thirsty virgins
