basal lamina of epithelium

The Planarian Anatomoy Ontology (PLANA) is a collection of terms curated from the literature and other organism anatomy ontologies to describe anatomical features, life cycle stages and developmental processes in the regenerative flatworm Schmidtea mediterranea. The latest version of the PLANA Ontology is available through the Open Biological and Biomedical Ontology Foundry (OBO) . PLANA Ontology terms are searchable at the EMBL-EBI Ontology Lookup Service (OLS) and the PLANA Ontology Terms Page.

The Overview Section is populated with infomration from the OLS.




Planarian Anatomy Ontology Term Overview


NAME:

  basal lamina of epithelium


DEFINITON:

  Acellular anatomical structure that consists of a thin sheet of fibrous proteins that underlie and support the cells of an epithelium. It separates the cells of an epithelium from any underlying tissue.


TERM CITATIONS:

  

TERM ID:

  PLANA:0001005


SYNONYMS:

  basal lamina of connective tissue, basal laminae, basal lamina, lamina basalis


ABOUT THIS TERM:

  basal lamina of epithelium "is a" acellular anatomical structure

  basal lamina of epithelium "contained in" dorsal compartment, tail, epidermal compartment, posterior compartment, copulatory region, ventral compartment, parapharyngeal region, anterior compartment, neck and head

  basal lamina of epithelium "existence overlaps" juvenile, asexual adult and sexually mature adult

  basal lamina of epithelium "immediately_deep_to" dorsal epidermis and ventral epidermis

  basal lamina of epithelium "immediately_superficial_to" body wall musculature

  basal lamina of epithelium "part of" integumental system


  basal epidermis surface "is a" basal lamina of epithelium


DEPICTED BY:


COMMENTS:

Depicted by field is an electron micrograph of the dorsal epidermis in a transverse plane from an asexual adult animal. The basal lamina is noted with a magenta bracket. Scale bar is 5um.


CURATOR NOTES:

  • this class represents a continuous sheet of basal lamina which can underlie multiple epithelial cells over large regions. In contrast, the GO class 'basal lamina' represents a portion of substance on the scale of a single cell.

HOMOLOGY NOTES:

  • A basal lamina is certainly present in Bilateria and was evaluated as an autapomorphy of this taxon.[well established][VHOG]
