Effect Of Amputation On Muscle Structure Properties In A Rabbit Model, Roy Caleb Stubbs
Effect Of Amputation On Muscle Structure Properties In A Rabbit Model, Roy Caleb Stubbs
Masters Theses
After amputation, muscles in the residual limb are detached from their insertion points and no longer span the missing joints. Our objective was to quantify the effect of amputation-induced disuse on residual muscle structure, an indirect indicator of muscle force-generating capacity. One hind paw was surgically removed at the ankle joint of ten rabbits. At two weeks (n=5) and 4 weeks (n=5) post-amputation and for select muscles (gastrocnemius, soleus, tibialis cranialis, extensor digitorum, and flexor digitorum superficialis), we measured and computed several muscle structure properties. Additionally, we qualitatively assessed the muscle fiber appearance of histological samples at each timepoint. At …
Comparative Anatomical Study Of The Brachial Plexus Of Primates, Alison Leann Camero
Comparative Anatomical Study Of The Brachial Plexus Of Primates, Alison Leann Camero
Masters Theses
Old world monkeys, new world monkeys, and humans all originate from a common ancestor. Although humans and old world monkeys are phylogenetically more closely related, old world monkeys and new world monkeys have similar locomotion. A difference in muscle patterns exists between old world monkeys, new world monkeys, and humans. Different musculature may be due to differences in locomotive patterns and species-specific use of their forearms. Muscles in the forelimbs are innervated by the nerves of the brachial plexus. There are differences among the brachial plexuses of human and non-human primates as well as variability within the species.

Effects Of 17Β Estradiol In The Metabolism And Morphology Of Bluegill Sunfish (Lepomis Macrochirus), Neeta Parajulee Karki
Effects Of 17Β Estradiol In The Metabolism And Morphology Of Bluegill Sunfish (Lepomis Macrochirus), Neeta Parajulee Karki
Masters Theses
Fish natural habitats are increasingly contaminated with various estrogenic compounds, including 17β estradiol (E2). This compound causes adverse effects on the reproductive system of male fish; however, the effects of E2 on other aspects of fish metabolism, morphology and histopathological changes in internal organs are not well known. The objective of this study is to evaluate the effects of E2 exposure on the basal and stressed metabolic rate, morphological changes in body shapes, and histological changes in the liver tissues of sunfish species. Fish were held individually in ten gallon tanks under two treatments of 40 and 80 ng/L and …

A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill
A Study Of Thoracic Skeletomusculature In Peracarida (Crustacea), Donna R. Gill
Masters Theses
Two species of peracarid malacostracans, a mysid, Neomysis americana, and an oniscid isopod, Trachelipus cf. rathkei, were used to study the skeletomusculature system. Serial sections, whole mounts, and gross dissections were made. Coxal promotors and remotors and basal adductors and abductors were the muscle groups examined.
The promotor and remotor muscles of N. americana were found to be numerous, well developed, taking origin primarily from the dorsal thoracic wall, and extending nearly ventrally to insert in the coxa; the adductor muscle and two abductor muscles are weakly developed. The coxa in T. cf. rathkei is incorporated completely …
