|March 25, 1977
Resumen
Las serpientes uropeltidas fosiles usan escamas corporales iridiscentes con crestas específicas para reducir la fricción y la adhesión del suelo. Sus colas contundentes tienen tapones protectores formados por la suciedad atrapada en escalas especializadas.
Área de la Ciencia:
- Zoología Zoología Zoología.
- La biofísica es la biofísica.
- Ciencia de los materiales Ciencia de los materiales.
Sus antecedentes:
- Las serpientes uropeltidas fósiles exhiben escamas corporales iridiscentes únicas.
- Estas escalas poseen microestructuras especializadas que influyen en las propiedades de la superficie.
Objetivo del estudio:
- Para investigar las bases estructurales de la iridiscencia en las serpientes uropeltidas.
- Comprender el significado funcional de la morfología de la escala en la locomoción y protección de los fósiles.
Principales métodos:
- Análisis de la microestructura a escala mediante el uso de microscopía electrónica.
- Observación de las propiedades superficiales relacionadas con la humedad y la adhesión de partículas.
Principales resultados:
- La iridiscencia es producida por crestas queratinosas espaciadas en 2500 Å.
- Los patrones de escala inhiben la humedad y la adhesión del suelo, reduciendo la fricción durante la excavación.
- Las escamas contundentes de la cola presentan espinas y crestas que forman un tapón de suciedad para la protección caudal.
Conclusiones:
- Las distintas estructuras de escala sugieren fuertes presiones selectivas tanto para la locomoción como para la protección.
- La iridiscencia en las serpientes fósiles tiene un doble papel en la reducción de la fricción y la adhesión del suelo.

01:12Regional Terms
Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

01:33Somatosensation
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
01:51Determination
During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In contrast, determination...
01:23Phylogeny
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire...
00:54Distribution and Dispersion
Ecology is the study of how organisms interact with their environment and with one another. An important aspect of ecology is understanding where species are found and how individuals are distributed within those areas. The geographic range of a species refers to the total area where its members are located, while dispersion describes the pattern of spacing of individuals within that range.Geographic Range and Dispersion PatternsWithin a species’ geographic range, individuals may be distributed...
01:54Convergent Evolution
Evolution shapes the features of organisms over time, ensuring that they are suited for the environments in which they live. Sometimes, selection pressure leads to the rise of similar but unrelated adaptations in organisms with no recent common ancestors, a process known as convergent evolution.The structures that arise from convergent evolution are called analogous structures. They are similar in function even if they are dissimilar in structure. Further, structures can be analogous while also...
