Tissue Biomechanics: Whales Have Some Nerve
نویسنده
چکیده
Nerves in the mouth of the rorqual whale can double in length during feeding, without incurring damage. Several clever structural features underlie this amazing phenomenon. Such neuroprotective architectural strategies may be conserved, to a lesser extreme, across the organismal spectrum.

Comparative feeding kinematics and performance of odontocetes: belugas, Pacific white-sided dolphins and long-finned pilot whales.
Cetaceans are thought to display a diversity of feeding modes that are often described as convergent with other more basal aquatic vertebrates (i.e. actinopterygians). However, the biomechanics of feeding in cetaceans has been relatively ignored by functional biologists. This study investigated the feeding behavior, kinematics and pressure generation of three odontocetes with varying feeding mo...
متن کاملTwo Levels of Waviness Are Necessary to Package the Highly Extensible Nerves in Rorqual Whales
Peripheral nerves are susceptible to stretch injury [1-4] and incorporate structural waviness at the level of the axons, fascicles, and nerve trunk to accommodate physiological increases in length [5, 6]. It is unknown whether there are limits to the amount of deformation that waviness can accommodate. In rorqual whales, a sub-group of baleen whales, nerves running through the ventral groove bl...
متن کاملCerebrospinal Fluid Pressure: Revisiting Factors Influencing Optic Nerve Head Biomechanics
Purpose To model the sensitivity of the optic nerve head (ONH) biomechanical environment to acute variations in IOP, cerebrospinal fluid pressure (CSFP), and central retinal artery blood pressure (BP). Methods We extended a previously published numerical model of the ONH to include 24 factors representing tissue anatomy and mechanical properties, all three pressures, and constraints on the op...
متن کاملBaleen Hydrodynamics and Morphology of Cross-Flow Filtration in Balaenid Whale Suspension Feeding
The traditional view of mysticete feeding involves static baleen directly sieving particles from seawater using a simple, dead-end flow-through filtration mechanism. Flow tank experiments on bowhead (Balaena mysticetus) baleen indicate the long-standing model of dead-end filtration, at least in balaenid (bowhead and right) whales, is not merely simplistic but wrong. To recreate continuous intra...
متن کاملPrinciples and methods of dental nerve tissue regeneration : a review
Background and Aim Today, tissue engineering is considered a significant approach in modern medicine, which is why research in biomaterials has focused on the development of advanced scaffolding for regenerative medicine. Many natural and synthetic polymers with a variety of origins have been used to make these scaffolds or are recommended by researches. These compositions usually have the pr...
