Cyematogenesis is the process of formation and development of kyema (chema).
Kyema (hema) is a gill apparatus characteristic of the larvae and embryos of aquatic vertebrates. Cyematogenesis begins in the early stages of embryonic development and leads to the formation of gill primordia.
The process of kiematogenesis includes the following stages:
-
The formation of the kyemoderm is a specialized ectodermal rudiment from which gills will subsequently develop.
-
Separation of kyemoderm into cue arches and cue pockets. The cue arches give rise to the cartilaginous skeleton of the gills, and the gill filaments themselves are formed from the cue pockets.
-
Differentiation of the epithelium of cue pouches and gill filaments.
-
Development of the vascular system of the gills.
-
Formation of innervation and muscles of the gills.
Thus, kiematogenesis is a complex process of morphogenesis, as a result of which the rudiments of the gill apparatus are laid down from the ectoderm and develop in the embryos of aquatic vertebrates.
Kiemogenesis is a process that occurs in the development of cinema. This is the process of formation and development of cinema culture, which begins from the birth of cinema and continues to the present day.
Cyematogenesis can be divided into several stages:
1. The birth of cinema - this stage begins at the end
