Studies in the comparative anatomy of the Clethraceae
These 20 species represent collections form the almost world wide distribution of this family. Anatomically all species studied were found to be homogeneous showing a gradual advancement from the most primitive species studied to the most advanced. From a morphological and geographical viewpoint …

Comparative anatomy and evolution of the gastrotrich muscular system
<p>Gastrotrichs figure prominently in metazoan phylogeny because they share a suite of complex morphological characteristics with several other members of the Bilateria. But their microscopic size, cryptic interstitial habitat, and lack of fossil record have exacerbated the usual barriers to …

Comparative Anatomy of the Stem in the Carrion Flowers (Apocynaceae-Asclepiadoideae)
… the group, surprisingly little is known of the comparative anatomy and morphology of its members. This study documents stem anatomical structure and cuticular characteristics of twenty-eight species representing fourteen genera of stapeliads. Materials were prepared for examination using …

The Comparative Anatomy of Extrafloral Nectaries in the Cactus Family (Cactaceae)
Extrafloral nectaries (EFNs) are specialized glands that unlike floral nectaries, which function primarily in pollination, are typically associated with plant defense, attracting invertebrates whose presence and activity can reduce herbivory. EFNs were first observed in cacti in 1837 and have been …

A Multimedia Atlas of Dissection for Comparative Anatomy of the Vertebrates
… methods of teaching the laboratory course for Comparative Anatomy of the Vertebrates could be improved by applying current computer technology to construct an interactive, multimedial atlas of dissection. Five specimens used in comparative anatomy courses at most institutions were chosen as …

Reconstructing Soft Tissues of Plio-Pleistocene Hominids using Comparative Anatomy of Modern Humans & Great Apes
The aim of facial approximation is to recreate the appearance of an individual from their dry skull. This technique has often been used following the discovery of a new species of ancient hominid, such as those belonging to the Australopithecus or Paranthropus genera. Facial approximations provide …

A STUDY OF THE GROSS, MICROSCOPIC, ULTRASTRUCTURAL, AND COMPARATIVE ANATOMY AND DEVELOPMENT OF THE ARTICULAR SURFACES OF THE HUMAN SACROILIAC JOINT
… the gross, microscopic, ultrastructural, and comparative anatomy and development of the sacroiliac joint are presented. Sacroiliac joints were obtained from 108 human, 43 bovine, 24 equine, 21 porcine, and 21 canine autopsies, spanning a full range of ages. The specimens were photographed and …

The greater Omentum - its Morphology and function
… along lines that were indicated. The Anatomy and Comparative Anatomy has received scant attention and the question of independent movement by the omentum has not yet been satisfactorily settled. These subjects have, therefore, been investigated and reported on at some length. In …

Feto-placental vascular structure and function: comparison of within and between species variations
… provides tools for consistent investigation of comparative anatomy between species, demonstrated on rat, mouse, and human data, and combined with the prediction of vascular resistance derived from imaging. Future expansion of this pipeline could investigate pathological placentas in animal …

The influence of developmental patterns on vertebrate evolution, with the evolution of the sacrum and pelvis as a case study
… history) and observations of extant clades (comparative patterns of pre- and postnatal development) is required to study the evolution of form across deep time. The pelvic complex plays a central role in tetrapod locomotion with the exception of taxa lacking hindlimbs (e.g., whales, snakes, …

Fossoriality In Snakes: Perspectives From Morphology And The Fossil Record
… have been relatively understudied in regards to comparative anatomy. In this project I examined segmented CT scans of 10 different species of Typhlopoidea, the largest clade of Scolecophidia. Using these comparisons I identified variability in several morphological characters not previously …

Put Your Back Into It: A Structural and Mechanical Characterization of Iliac Crest and Cervical Spine Autograft for ACDF Surgeries
… mechanical and material properties in a bovine comparative anatomy model. Here, trabecular bone from the lumbar vertebra was found to be transversely isotropic whereas iliac crest trabecular bone was nearly isotropic; thus, directionality and anatomical location should be considered and …

The Multituberculates as Living Animals: New Insights into the Ecomorphology, Behavior, and Life History of One of the Most Successful Mammalian Lineages
… I use a combination of linear morphometrics, comparative anatomy, functional morphology, sedimentology, taphonomy, and bone histology to shed further light on the ecomorphology, behavior, and life history of multituberculates. In particular, this dissertation focuses on the fossil record of …
