The neural plate invaginates
beneath the epidermal layer to form the neural tube.
26) Additionally, there may be a role for sinonasal endoscopic treatment for selected patients with a symptomatic arachnoid cyst that abuts or invaginates
into the paranasal sinuses.
To regenerate the missing digestive system, the body wall begins to invaginate
In the myriapods so far investigated, ganglia form in a different way and can vary somewhat: clusters of tightly packed cells invaginate
into the interior of the embryo.
We suppose that the ectodermal epithelium and the invaginate
d archenteron are physically continuous during the invagination processes and that the blockage of invagination is mainly due to physical constraint of the ectodermal layer attached to the glass dish.
Proximally, the lateral walls of the diverticulum invaginate
to form tracheoesophageal folds, which eventually fuse in the midline.
De-flagellated larval epithelia do not invaginate
in a cell sheet, but are disarranged into individual amoeboid cells that each migrate to the inner region of a metamorph by amoeboid movement.
The lining epithelium of inverted papillomas most often is a non-keratinizing, stratified squamous type of epithelium that invaginates
in the underlying stroma.
Retrograde gastric intussusception is a rare type of intussusception where a part of the stomach with all layers invaginates
into the oesophagus (2).
1) It is a benign tumoral entity covered with columnar or cuboid epithelium with a cystic appearance characterized by proliferation of Von Brunn islets (transitional epithelium which invaginates
into lamina propria, a process induced by irritation in chronic cystitis mimicking carcinomatous invasion).
The uterus develops from celomic epithelium during the 6th week of development during which it invaginates
to form paramesonephric duct (mullerian duct).
Two tissue layers (endoderm and ectoderm) develop as one side of the embryo invaginates
to form the gut.
