  1. 1. Osteoarthritis in feline coxofemoral joints : a comparison of diagnostic imaging and histologic findings

    University essay from SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Author : Gabriela Ramer; [2019]
    Keywords : osteoarthritis; coxofemoral joint; feline; computed tomography; radiography;

    Abstract : Osteoarthritis (OA) is a progressive, low-grade inflammatory disease of synovial joints. It is characterized by the degradation of articular cartilage but involves the whole joint including the subchondral bone and soft tissues. READ MORE

  3. 2. Evolution of the Vascular Pattern in Mammals : Using Synchrotron Imaging to Visualise Hidden 3D Structures

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Jasper Ponstein; [2017]
    Keywords : Secondary ossification centres; Mammalia; vascularity; limb-bone evolution; Sekundära ossifieringscentra; däggdjur; vaskuläritet; lembensutveckling;

    Abstract : The morphology and histology of long bones are important tools for understanding tetrapod locomotion and growth. In mammals, the epiphyses of long bones ossify from a secondary centre of ossification. The consensus is that vascular canals are closely tied to the formation of these centres. READ MORE

  4. 3. Long bone and vertebral microanatomy and osteo-histology of ’Platecarpus’ ptychodon (Reptilia, Mosasauridae) : implications for marine adaptations

    University essay from Lunds universitet/Geologiska institutionen

    Author : Miriam Heingård; [2014]
    Keywords : benhistologi; mikroanatomi; mosasaurier; akvatisk anpassning; tillväxthastighet; bone histology; bone microanatomy; mosasaurs; aquatic adaptations; growth rate; Earth and Environmental Sciences;

    Abstract : The inner bone architecture and histology provide information about life history traits of extant as well as extinct animals. Mosasaurs (family Mosasauridae) are a group of secondarily adapted marine squamates that radiated in the Late Cretaceous, resulting in the evolution of a body plan adapted for pelagic habitats.

  5. 4. Enigmatic basal archosauromorph from the Late Triassic of Poland

    University essay from Evolution och utvecklingsbiologi; Institutionen för biologisk grundutbildning

    Author : Olja Toljagic; [2012]
    Keywords : ;

    Abstract : Choristodera, a lineage of basal archosauromorphs (Reptilia: Diapsida), first appeared in Early/Middle Jurassic (possibly Late Triassic; approximately 201 million years ago) and extended all the way into early Miocene (approximately 23 million years ago). Choristoderans are the only group of more basal archosauromorphs that survived after the Jurassic period, along with Archosauriformes (a more derived group of Archosauromorphs). READ MORE

  6. 5. Osteo-histology of Mesozoic marine tetrapods : implications for longevity, growth strategies and growth rates

    University essay from Lunds universitet/Geologiska institutionen

    Author : Johan Gren; [2010]
    Keywords : histologi; mesozoiska tetrapoder; livslängd; tillväxtstrategier; osteoporos; pachyosteosclerosis; histology; Mesozoic tetrapods; longevity; growth strategies; osteoporosis; Earth and Environmental Sciences;

    Abstract : Osteo-histology provides information on age, growth strategies, and lifestyles of both recent and ancient animals. This study deals with the histology of fossilized bone from three groups of tetrapods – sea turtles, ichthyosaurs and plesiosaurs – all secondarily adapted to marine life, but with rather different bone microstructures.
