Record 2 2021-12-21

English

Subject field(s)
  • Scientific Measurements and Analyses
  • Fish
DEF

A clear variation in the angle of the corpus calcareum [that] corresponds to a growth rate acceleration in [fish].

CONT

Recent declines in abundance of skates... have heightened the need for validated age and growth estimates... skate vertebral centra collected seasonally... were sectioned using a mass processing method, then used to reconstruct growth in each species.... Total counts were obtained by summing visible and estimated band counts. Growth curves were then fitted to all length-at-age data including sections deemed unreadable near the focus. The location of the birth band(BB) in each species was confirmed by comparing suspected birth band radius(BR) measurements with [vertebral radius(VR) ] measurements of available late-term embryos... and/or early young-of-the-year fish... Regressions between VR and [total length] for each species, along with published hatch lengths, were also used to verify the location of the BB along the corpus calcareum of each section...

OBS

Birthmarks are usually represented by an angle change along the centrum face of whole vertebrae or along [the] intermedialia-corpus calcareum interface with an associated ring on the corpus calcareum in sectioned centra, but this feature may not be distinct in either.

Record 3 2021-08-02

English

Subject field(s)
  • Bones and Joints
  • Morphology and General Physiology
DEF

Any of the primitive cartilages or structural elements of which a typical vertebra is formed.

CONT

As the development proceeds, the arcualia develop gradually enclosing the spinal cord dorsally and the blood vessels ventrally, thus, forming the neural and haemal arches. Since there are two sclerotome halves to a somite, two arches to each segment may be formed. In the adult lamprey, for instance, there are two arches to each body segment, [which] persist throughout life though no centra are formed... The formation of centrum does not depend on arcualia alone.

OBS

arcuale; arcualium: designations usually used in the plural.

OBS

arcualia: plural.

Domaine(s)

CONT

Vertèbre acrocentrique : le corps vertébral est dérivé de l'édification squelettique des arcualies, avec participation de la chorde et de ses gaines.

Record 4 2010-10-06

English

Subject field(s)
  • Radiography (Medicine)
  • Musculoskeletal System
DEF

Metatropic dwarfism is first manifested by marked streaklike underossifications of the vertebral centra, wide metaphyseal flaring, and trochanteric hyperplasia. Its progressively severe kyphoscoliosis and peculiar battle-axe pelvic configuration, with marked iliac flaring, distinguish it from spondyloepiphyseal dysplasia.

Dans la dysplasie métatropique, on note au bassin un élargissement des ailes iliaques avec un aspect en hallebarde et une encoche externe. [D'après LAVOS, 1983, volume 10, p. 190.]

English

Subject field(s)
  • Bones and Joints
  • Mammals
CONT

These vertebrae bear long ribs... The majority of the thoracic vertebrae have very tall neural spines, directed caudad, short centra, small pre-and-post-zygapophyses, and short stout transverse processes(diapophyses) to whose outer ends the tubercula of the ribs articulate.

French

Domaine(s)
  • Os et articulations
  • Mammifères
CONT

Les «vertèbres thoraciques» ou «dorsales» [des mammifères] sont caractérisées par les apophyses articulaires sur lesquelles s'articulent les «côtes»; sur leurs «apophyses épineuses» très développées s'attachent les «ligaments cervicaux» qui soutiennent la tête.

OBS

These are very variable in number among mammals, as shown by the varying tail lengths, and run from a few up to fifty. Neural arches, transverse processes, and zygapophyses diminish caudally, so that the last vertebrae consist only of centra.

Subject field(s)
  • Gas and Oil Heating
DEF

A gas that Centra Manitoba [natural gas supplier] purchases, when required, to ensure supply is available when demand is haigher than normal.

CONT

During normal weather, Primary Gas represents about 94 per cent of your annual gas use and supplemental Gas represents about six per cent. When weather is warmer than normal, your Supplemental Gas supply may represent less than six per cent of your total use, and consequently, Primary Gas may represent more.
