Sphenoidal Sinuses And Spherical Harmonics: Variation And Covariation Of The Most Morphologically Diverse And Least Understood Paranasal Sinus, Katharine Grace Josephine Ryan
Sphenoidal Sinuses And Spherical Harmonics: Variation And Covariation Of The Most Morphologically Diverse And Least Understood Paranasal Sinus, Katharine Grace Josephine Ryan
Doctoral Dissertations
Understanding the shape variation of the human sphenoidal sinus is important to several areas of research. This includes clinical investigation (sinus pathology and safe endoscopic endonasal surgical practice) and paranasal sinus evolution (for which there is still no consensus). Yet, the sphenoidal sinus has high morphological variation, prohibiting its quantification through traditional geometric morphometric landmarking methods. The sphenoid body, and thus also the sinus contained within, is located directly at the developmental center of the basicranium in humans, where the three cranial fossae meet at the midline, and adjacent to the three synchondroses which are the sites of cranial base …
Primate Olfaction: A Phylogenetic Analysis Of Cribriform Plate Morphology, Amber Cooper
Primate Olfaction: A Phylogenetic Analysis Of Cribriform Plate Morphology, Amber Cooper
Anthropology Undergraduate Honors Theses
Decreased olfaction, or smell, is a diagnostic characteristic of primates. Despite this, olfaction remains important for diet and social behaviors in primates. To assess how morphological changes impact olfactory-based behaviors between the two major clades of primates, Strepsirrhini and Haplorrhini, this study examined the surface area of the cribriform plate, the bony interface between the brain and nasal cavity. Previous work has found several functional associations between cribriform plate morphology and species diet/ ecology, making this structure possibly more reflective of a species reliance on olfaction in its environment. Primate social structure, such as average group size, mating system, and …
Tooth Crown Morphology And Testosterone Transfer In Female Members Of Opposite-Sex Dizygotic Twin Pairs, Randall Feezell
Tooth Crown Morphology And Testosterone Transfer In Female Members Of Opposite-Sex Dizygotic Twin Pairs, Randall Feezell
Graduate Theses and Dissertations
The twin testosterone transfer (TTT) hypothesis posits that females gestated with male co-twins develop more masculine phenotypes due to in-utero androgen exposure. Research has shown co-gestational effects to be associated with increased deciduous and permanent tooth size in females belonging to opposite-sex dizygotic twin pairs (OSF) as compared with females belonging to same-sex monozygotic (MZF) and dizygotic (SSF) twin pairs and female siblings. This study evaluates whether the TTT hypothesis explains patterns of dental morphological variation, namely differences between OSF and other females (SSF, MZF, female siblings) in a contemporary sample that includes both deciduous and permanent data. This work …
