Descripteur : Type of Intervallar cells

Type du descripteur : 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.


Calicles

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.

Syringe

Syrinx (plur. syringes): Intervallar structure comprising porous radial horizontal or curved tube with hexagonal or tetragonal cross-section.

Intervallum: Space enclosed between the walls.

NB: Syringes horizontally distributed structure observed in longtidutinal section.
