After crossing, Robo-1/2 is upregulated and again inhibits crossing via the ligand slit (3). Netrins: Netrins are proteins expressed and secreted by cells of the floor plate. Experiments using floor plate extracts and commissural neurons embedded in a collagen matrix show attraction of neurons towards the floor plate in vitro. [8]
The etymology of the word "morphology" is from the Ancient Greek μορφή (morphḗ), meaning "form", and λόγος (lógos), meaning "word, study, research".

Evolutionary developmental biology seeks to explain the origins of diverse body plans. Body plans have historically been considered to have evolved in a flash in the Ediacaran biota ; filling the Cambrian explosion with the results, and a more nuanced understanding of animal evolution suggests gradual development of body plans throughout the ...

Such symmetry has evolved because it allows the viral particle to be built up of repetitive subunits consisting of a limited number of structural proteins ...
