The Anatomical Record, EarlyView.Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

The ontogenesis of the steroidogenic tissues [PDF]
Genes to Cells, 1997 Based on the common function of steroid hormone‐producing tissues and homologous regulation by the hypothalamo‐pituitary axis, the adrenal cortex and the gonads have been suggested to have an intimate ontogenic relationship. This assumption is also supported by the findings of common transcription factors implicated in the differentiation of both types

An osteohistological analysis of Triceratops (Ornithischia: Ceratopsidae) cranial ornamentation
The Anatomical Record, EarlyView.Abstract Ceratopsids are among the most distinctive and well known extinct Cretaceous vertebrates, yet many details regarding the growth and composition of their cranial features are still not fully anatomically described or understood. In particular, striking cranial adornments such as the postorbital horns and parietal‐squamosal frill of Triceratops ...

The Energy-Sources in Ontogenesis [PDF]
Journal of Experimental Biology, 1926 ABSTRACTThe percentage growth-rate curves for carbohydrate and protein in the chick enbryo have been determined and compared with those already in the literature for the percentage growth-rates of the whole embryo, the dry substance, the fat, and the calorific value. The composition of the embryo in gm.

The Anatomical Record, EarlyView.This review redefines the carotid bulb (CB) as a variable geometric dilation shaped by hemodynamics and the carotid sinus (CS) as a conserved neurohistological baroreceptor field. Distinguishing these entities clarifies a century of anatomical confusion and links geometry, neurohistology, and clinical interpretation within a unified framework ...

The Anatomical Record, EarlyView.Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...
