S

The horn of the hoof wall that is produced by the coronary corium. This forms the stratum medium which makes up most of the wall substance.

It consists of many elongated cylinders of horn (horn tubules) lying parallel to each other and running continously from the coronary band to the bearing edge. The horn tubules are grown from the epidermis of the cornary papillae; between the tubules, the strong intertubular horn forms a matrix in which the tubules are embedded. This type of horn grows from the coronary epidermis between the papillae.The horn varies slightly in structure and pigmentation from the outer-most layers (high tubular density, usually pigmented) to the inner-most layers (low tubular density, un-pigmented).

Français
  • corne pariétale, f
  • corne tubulaire, f
  • stratum medium, m

Corne formée par le chorion coronaire. C'est la couche de corne intermédiaire et la plus dense de la paroi; au microscope on peut distinguer les tubules avec la corne intertubulaire. À l'intérieur de cette couche, on observe également de légères variations: partant de l'extérieur vers les couches profondes, le nombre des tubules décroît, ainsi que la pigmentation.

Deutsch
  • Kronhorn, n

Vom Kronsegment gebildetes Horn. Mittlere und dickste Schicht des Wandhornes, mikroskopisch als Hornröhrchen mit Zwischenröhrchenhorn zu erkennen.

Innerhalb dieser Schicht gibt es von aussen nach innen leichte Variationen bzgl. Anzahl der Hornröhrchen und der Pigmentierung. Von aussen nach innen nimmt die Zahl der Hornröhrchen ab, die innere Schicht ist immer unpigmentiert.
