placode मीनिंग इन हिंदी

उदाहरण वाक्य

1. As development progresses, the lens placode begins to deepen and invaginate.
2. The second stage occurs at E11.5 when placode formation begins along the mammary milk line.
3. During development, primitive olfactory neurons extend their axons from the olfactory placode, through the mesenchyme, towards the telencephalic vesicle.
4. In chick embryos it is shown that ectopically expressed noggin produces enlarged follicles, and BMP4 signaling shows repressed placode fate in nearby cells.
5. Derived from the embryonic nasal placode, the olfactory nerve is somewhat unique among cranial nerves because it is capable of some regeneration if damaged.
6. As the placode continues to deepen, the opening to the surface ectoderm constricts and the lens cells forms a structure known as the lens vesicle.
7. Lastly, the third stage occurs at E12.5 and involves the invagination of cells within the placode into the mesenchyme, leading to a mammary anlage ( biology ).
8. The optic visicle will then induce the ectoderm that thickens ( lens placode ) and further invaginates to a point that detaches from the ectoderm and forms a neurogenic placode by itself.
9. The optic visicle will then induce the ectoderm that thickens ( lens placode ) and further invaginates to a point that detaches from the ectoderm and forms a neurogenic placode by itself.
10. The term " neurogenic placode " generally refers to cranial placodes that have neurogenic potential-i . e . those that give rise to neurons associated with the special senses and cranial ganglia.
