Variations in the Morphology of Foramen Lacerum
Journal of Craniofacial Surgery, 2020Abstract Greater petrosal and deep petrosal nerves unite in foramen lacerum to form vidian nerve which innervate lacrimal, buccal, nasopharynx, and nasal glands. Moreover, the superior part of this foramen transmits lacerum part of internal carotid artery which irrigates major part of brain.

The Morphological Variations of Fibrous Histiocytomas
Journal of Cutaneous Pathology, 1974The morphological variants of dermal fibrous histiocytomas have engendered a confusing terminology. One hundred and eighty‐nine cases of fibrous histiocytomas were studied in order to define the morphological spectrum exhibited by these lesions.Based on the prevailing morphological components, fibrocollagenous, vascular, or histiocytie.

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.

Variations of Capitate Morphology in the Wrist
The Journal of Hand Surgery, 2008This anatomical study details and categorizes variations in capitate morphology and associated structures in the human cadaveric wrist.We dissected 107 cadaveric wrists. Capitate morphology, the presence of capitate and hamate ridges, the lunate types, and the width of the medial hamate facet of type II lunates and 4th carpometacarpal joint types were ...

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 ...

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 ...

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 ...

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 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
