Retinal pigment epithelial fine structure in \n\t\t\t\t the Australian Galah (Eolophus roseicapillus) (Aves)
Bibliographic record
Abstract
As part of a comparative morphological \n\t\t\t\t study, the fine structure of the retinal epithelium (RPE), \n\t\t\t\t choriocapillaris and Bruch's membrane (complexus \n\t\t\t\t basalis) has been investigated by light and electron \n\t\t\t\t microscopy in the galah (Eolophus I-oseicapillus), an \n\t\t\t\t Australian cockatoo. The RPE consists of a single layer \n\t\t\t\t of low cuboidal cells joined basally by a series of \n\t\t\t\t zonulae occludentes. Basally (sclerally) the retinal \n\t\t\t\t epithelial cells display numerous deep infoldings while \n\t\t\t\t apically (vitreally) microvillar processes interdigitate \n\t\t\t\t with photoreceptor outer segments. Internally the RPE \n\t\t\t\t cells show a large vesicular nucleus, plentiful smooth \n\t\t\t\t endoplasmic reticulum (SER) and numerous polysomes \n\t\t\t\t but very little rough endoplasmic reticulum (RER). \n\t\t\t\t Numerous mitochondria are located basally. In the lightadapted \n\t\t\t\t specimens studied, the melanosomes of the RPE \n\t\t\t\t are almost exclusively located within the apical \n\t\t\t\t processes indicating that retinomotor movement of this \n\t\t\t\t pigment probably occurs. Phagosomes and lysosomelike \n\t\t\t\t bodies are present as are myeloid bodies which may \n\t\t\t\t show ribosomes on their outer surface. The choriocapillaris \n\t\t\t\t endothelium is thin but only minimally fenestrated \n\t\t\t\t facing Bruch's membrane. Most fenestrations of the \n\t\t\t\t choriocapillaris display a single-layered diaphragm \n\t\t\t\t while the remainder have a double-layered diaphragm. \n\t\t\t\t Bruch's membrane (complexus basalis) is typical of \n\t\t\t\t avian species in that it is pentalaminate with the central \n\t\t\t\t lamina densa displaced towards the choriocapillaris.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
