|
epithelium
|
Portion of tissue, that consists of one or more layers of cells with distinct apical-basal polarity, connected to each other by cell junctions. |
|
FBbt:00000014
|
labial segment
|
Most posterior of the gnathal segments. In the adult it bears a pair of fused appendages, the labia, and its ectodermal invaginations give rise to the salivary glands. |

|
|
|
FBbt:00001061
|
ventral neurectoderm
|
The ventrally/medially located ectodermal region of the trunk from which neuroblasts delaminate to form the ventral nerve cord. This region becomes distinct during stage 8 when its cells become enlarged compared to those in the adjacent dorsal ectoderm. |
|
FBbt:00000110
|
germ layer
|
Primordium that is a primary subdivision of the embryo into regions based on tissue and cell-type fate and specification. Germ layers first become morphologically distinct during gastrulation. As a result of gastrulation, the endoderm becomes the inner-most layer, the mesoderm becomes the middle layer and the ectoderm becomes the outer layer. |

primordium
|
Primordia are populations of contiguous cells that are morphologically distinct and already correspond in extent to a later organ/tissue. |

organism subdivision
|
Anatomical structure that is a primary subdivision of whole organism. The mereological sum of these is the whole organism. |

FBbt:00007001
|
anatomical structure
|
Material anatomical entity that has inherent 3D shape, whose parts are all connected and that is generated by coordinated expression of the organism's own genome. |
|

|
portion of tissue
|
Anatomical structure, that consists of similar cells and intercellular matrix, aggregated according to genetically determined spatial relationships. |
