Descriptor : Type of Intervallar cells
Descriptor type : categorical
Intervallar cell: Part of intervallum bounded by adjacent radial-longitudinal partitions and tangential synapticulae.
Intervallum: Space enclosed between the walls.
Synapticula (plur. synapticulae): Narrow horizontal rod linking two adjacent vertical intervallar structures.
NB:
Calicles vertically distributed structure observed in transverse section.
Syringes horizontally distributed structure observed in longtidutinal section.

Calicle: Longitudinal tubelike intervallar structure, which can be hexagonal or tetragonal in cross-section.
Intervallum: Space enclosed between the walls.
NB: Calicles vertically distributed structure observed in transverse section.
