Formation of Muscle Fibers from Myoblasts

De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers. Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription factors...

Sign Test for Matched Pairs

The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values. To conduct the sign test, we first calculate the differences in value between...

We describe a technique for inscribing identical fiber Bragg gratings into each core of a multicore fiber. This is achieved by introducing an additional surface into the optical path to mitigate lensing by the curved surface of the fiber cladding.

In Vivo Single-Fiber Recording of Sciatic Nerve C-Fibers in Rats
0 Views •
2025
This video demonstrates a single-fiber recording of C-fiber nerve conduction in rats. An anesthetized rat is incised to expose the sciatic nerve, which provides sensory and motor supply to the lower limbs. The individual C-fibers are then exposed. Electrical stimulation is provided using stimulus electrodes implanted in the foot, and a response is recorded from a single nerve fiber.
FAQs
Deposition conditions determine how individual fibers are arranged within the mat, influencing orientation, thickness, and porosity. A controlled architecture can change the balance between permeability and mechanical strength, while fiber placement also affects the available surface area. Engineering these variables allows a continuous sheet or three-dimensional network to meet different structural and transport requirements.
These consolidation mechanisms convert a deposited fiber assembly into a more stable structure. Mechanical entanglement holds fibers together through their interconnection, while thermal bonding and chemical binders strengthen contact between fibers through processing-induced bonding. Selecting among them affects the resulting mat's mechanical integrity, surface properties, and suitability for a particular engineering application.
Porosity controls how much open space exists within the fiber network, directly influencing permeability and the material's accessible surface area. Increasing or reducing this structural feature changes how the mat balances fluid transport with mechanical integrity. Engineers therefore adjust architecture and processing conditions when designing mats for filtration, insulation, energy devices, or scaffolds.
The deposition route determines the environment in which fibers assemble before consolidation. Dry, wet, and other fluid-based processes can produce different arrangements and therefore influence orientation, thickness, porosity, and strength. Comparing these routes helps engineers select processing conditions that provide the required architecture rather than treating fiber deposition as independent from final performance.
A typical workflow begins by depositing individual fibers through a dry, wet, or fluid-based process. The resulting assembly is then consolidated through mechanical entanglement, thermal bonding, chemical binders, or solvent removal. Engineers evaluate the resulting thickness, porosity, orientation, and strength to determine whether the structure provides the intended balance of permeability, integrity, and surface properties.
This approach is useful when a lightweight material must also provide high surface area and a controlled internal architecture. Its resulting mats can support filtration, reinforcement, insulation, energy-device, and biomedical-scaffold applications. The method is especially relevant when designers need to balance fluid permeability or surface behavior against the mechanical integrity required in service.
In advanced composites, a fiber mat can provide reinforcement while maintaining a lightweight structure. In biomedical engineering, its porous architecture and controllable surface properties support scaffold design. These uses depend on adjusting deposition and consolidation conditions so the final network provides an appropriate combination of strength, porosity, surface characteristics, and structural continuity.
