Resumen
La lengua fría del Pacífico se desarrolló debido al enfriamiento en las regiones subantárticas y subárticas. Este enfriamiento también alteró los patrones climáticos, apoyando la hipótesis de cambios oceanográficos durante la transición Plioceno-Pleistoceno.
Área de la Ciencia:
- La paleoceanografía es la paleoceanografía.
- Ciencias del clima Ciencias del clima Ciencias del clima
- Oceanografía La oceanografía es la oceanografía.
Sus antecedentes:
- La lengua fría del Pacífico ecuatorial oriental es una característica clave del océano que influye en el clima global.
- Su desarrollo del Plioceno-Pleistoceno está relacionado con el shoaling de la termoclina impulsado por el enfriamiento extratropical.
Objetivo del estudio:
- Investigar el enfriamiento sincrónico en las regiones subantárticas y subárticas con desarrollo de lengua fría.
- Examinar los cambios en la respuesta del clima subantártico a las variaciones orbitales.
Principales métodos:
- Análisis de datos proxy paleoclimáticos de las regiones subantárticas y subárticas.
- Comparación del tiempo de enfriamiento regional con el surgimiento de la lengua fría.
- Evaluación de los cambios en la respuesta del clima a los ciclos orbitales de la Tierra.
Principales resultados:
- Se produjo un enfriamiento sustancial en las regiones subantárticas y subárticas, coincidiendo con el desarrollo de la lengua fría.
- El clima subantártico cambió de un patrón subtropical a uno subpolar en respuesta al forzamiento orbital.
- La evidencia apoya la hipótesis de que el enfriamiento de los océanos condujo a la acumulación de la termoclina y la contracción de los giros.
Conclusiones:
- El enfriamiento extratropical jugó un papel importante en el desarrollo del Plioceno-Pleistoceno de la lengua fría del Pacífico.
- Los cambios climáticos observados indican una contracción de la esfera de agua caliente del océano y giros subtropicales.

00:49The Tongue and Taste Buds
34.7K
The surface of the tongue is covered with various small bumps called papillae, which either distribute what has been ingested (filiform papillae) or contain the sensory taste (or gustatory) receptor cells (fungiform, circumvallate, and foliate papillae). Embedded within each taste-related papilla are the taste buds—clusters of 30 to 100 gustatory receptor cells.

01:43Gustation
43.5K
Gustation is a chemical sense that, along with olfaction (smell), contributes to our perception of taste. It starts with the activation of receptors by chemical compounds (tastants) dissolved in the saliva. The saliva and filiform papillae on the tongue distribute the tastants and increase their exposure to the taste receptors.

01:43Thermosensation
29.7K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...

01:24The Physiology of Taste
6.8K
The perception of a salty flavor is facilitated by sodium ions within the oral salivary fluid. Upon consumption of a salty substance, salt crystals disassemble, leading to the liberation of its constituents—Na+ and Cl- ions. These ions subsequently dissolve into the salivary fluid present in the oral cavity. The external environment of the gustatory cells experiences an elevation in Na+ concentration, thereby establishing a potent concentration gradient. This gradient propels the...

The human tongue is a fascinating and complex organ, responsible for various essential functions such as swallowing, speech, and taste. It is also subject to various conditions and diseases. In this article, we delve into the anatomy of the tongue, its roles, and some common conditions that can affect it.
Anatomical Position in the Oral Cavity
The tongue is located within the oral cavity, also known as the mouth. It is attached to the floor of the mouth by a fold of mucous membrane called the...

01:19Formation of Lipopolysaccharides
1.1K
Lipopolysaccharides (LPS) are crucial components of the outer membrane of Gram-negative bacteria, serving both structural and functional roles. It contributes to membrane stability and protects bacteria from host immune responses. LPS is composed of three major regions—lipid A, a core oligosaccharide, and an O antigen. The biosynthesis and assembly of LPS involve a highly coordinated set of enzymatic reactions and transport mechanisms. Additionally, LPS is recognized as an endotoxin,...
