Morphologic Variations in Graft Endothelium
Archives of Ophthalmology, 1980The morphologic features of corneal endothelium were studied with clinical specular microscopy in 33 cases of clear corneal transplants. A complete morphologic profile of the corneal endothelium, which included cell density, mean cell area, and variation in cell size (polymegethism), was obtained with an automated, pattern-analysis system.

Morphological Variations of the Ulnar Styloid Process
Journal of Hand Surgery, 1990P.A. radiographs of both wrists were taken in 400 normal individuals to study the configuration of the styloid process of the ulna. Five different morphological variations were noticed, the commonest being an elongated process (102 wrists). Medially deviated (41 wrists), parrot beaked (27 wrists) and hypertrophic (16 wrists) patterns were less common ...

The principles of twofold vowel harmony and fourfold vowel harmony form, together with a number of consonant assimilations, the core of what at first sight looks like an enormous variation in suffixes. Since this apparent proliferation is largely predictable, it can neatly be reduced by adopting archetypical notations: –(y)E can be rewritten as four ...

Ontogenetic variation in human nasal morphology
The Anatomical Record, 2021AbstractInternal nasal cavity morphology has long been thought to reflect respiratory pressures related to heating and humidifying inspired air. Yet, despite the widely recognized importance of ontogeny in understanding climatic and thermoregulatory adaptations, most research on nasal variation in modern and fossil humans focuses on static adult ...

Morphological Variation and Speciation
Systematic Botany, 1985Developmental factors (e.g., canalization, plasticity, epistasis) weaken the integration of genomic and morphological diversification. Numerous non-lethal morphological mutations and several cases of substantial morphological differentiation associated with negligible isozymic di- vergence have been documented. These observations suggest that evolution

Functional Morphology and Morphological Variation
1984The apparent simplicity of the cellular structure of sponges has generated much interest in this phylum of primitive metazoans, particularly the capacity of some types of adult cells to act in a seemingly embryonic fashion. In at least some species, nonepithelial cells differentiate into a number of functional cell types including spicule-secreting ...

Morphological variations in the dendritic spines of the neocortex
Journal of Cell Science, 1969ABSTRACT The structural variations which occur in the dendritic spines of pyramidal neurons of the somatic sensory cortex of the cat are described, particular attention being paid to spines attached to different parts of the dendritic tree.

Morphological variation in the Weberian apparatus of Cypriniformes
Journal of Morphology, 2007AbstractCypriniformes (which includes the minnows, carps, loaches, algae‐eaters, stone loaches, and suckers) is a morphologically diverse and incredibly speciose order of teleosts. It has been suggested that a number of evolutionary innovations, key to improved hearing and feeding, have played an important role in cypriniform fishes' success.

Morphological Variations of Human Ossicula Tympani
Cells Tissues Organs, 1988In a series of 100 cases, morphological variations of human ossicula tympani were studied. These have seldom been considered either in classic or recent descriptions. Among them, the malleus and stapes are the most variable ones. A geometric model is proposed to systematically study any variation from the typical ossicles.

Morphological Variation and Change
1992Abstract In this chapter I will discuss two aspects of the morphological structure of Tok Pisin. One of these affects the pronominal system, in particular the distinction between inclusive and exclusive pronouns and the dual (7.1), and the other concerns the introduction of noun pluralization by suffixation of English -s (7.2).
