Preferred Label : pectoral fin fold;
Uberon definition : The functional webs of the paired fins. They arise as a consequence of apical fold
(AER) expansion and of migration of the distal mesenchyme. The fin folds are delimited
by a dorsal and a ventral striated epidermis. The cells of the epidermal basal stratum
are positioned on a basement membrane. Directly beneath the basement membrane of each
side there is an array of actinotrichs, fibers of the extracellular matrix which act
as supportive elements of the larval fin folds.;
