Descriptor : Carcass perforations: inner wall (IW)

Descriptor type : categorical

Carcass: Part of wall on intervallum side.

Inner wall: Internal part of the skeleton, separating central cavity and skeletal structures, composed by a porous carcass, simple or coated by an additional sheath.

Carcass perforations: inner wall (IW)


Pores

Pore: Simple perforation of any skeletal structure. Pore diameter is greater than thickness of the structure.

Pores

Canals

Canal: Pore modified by skeletal structure thikening or by lintels streching. Canal length is greater than perforation diameter.

Lintel: Skeletal structure separating and bounding adjacent pores.

Vertical tubes

Vertical tube: One canal-like opening, longitudinally continuous along entire cup, bounded by longitudinal plates and lacking transverse partitions.
