We demonstrate a protocol for axoplasm isolation from adult rat sciatic nerve based on dissection of nerve fascicles and incubation in hypotonic medium to release myelin and lyse non-axonal structures, followed by extraction of the remaining axon-enriched material.

Fascicle Arrangement in Skeletal Muscles

2025
Fascicles are bundles of muscle fibers in a skeletal muscle. Muscle fascicle arrangement is directly associated with the power and range of motion of various muscles. The configuration of these fascicles can vary, leading to different functional outcomes. The four primary types of muscle based on fascicle arrangement are: Parallel Muscles: In this type, fascicles run parallel to the long axis of the muscle. Examples include the biceps brachii and the rectus abdominis. When parallel muscles...

In Vivo Single-Fiber Recording of Sciatic Nerve C-Fibers in Rats

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
Preserving the perineurium is central because it maintains the boundary around an individual fascicle during manipulation. This boundary helps keep the isolated bundle structurally identifiable while the operator works under magnification. Minimizing traction-related damage is equally important, since excessive pulling can compromise the tissue preparation and reduce its value for later anatomical, histological, or electrophysiological study.
Connective tissue planes provide the natural interfaces that distinguish neighboring fascicles within a peripheral nerve. Following these planes allows the operator to separate bundles selectively rather than relying on forceful mechanical division. Their careful identification supports more controlled manipulation, helps preserve fascicular boundaries, and reduces the likelihood that traction will damage tissue needed for structural or functional analysis.
The arrangement of fascicles can help investigators examine how peripheral nerve structure relates to functional pathways. Isolated bundles make this organization more accessible for anatomical study and targeted manipulation. This structural perspective is relevant to research that connects fascicular patterning with selective nerve repair, grafting strategies, and the design or evaluation of neuroprosthetic approaches.
A careful workflow includes exposing the nerve, using magnification to inspect its internal organization, identifying the connective tissue planes between fascicles, and advancing through those planes with gentle manipulation. Throughout the procedure, the operator prioritizes preservation of the perineurium and avoidance of traction-related injury. These priorities determine whether the resulting fascicles remain suitable for downstream research or surgical investigation.
Separated fascicles can provide tissue preparations for several complementary forms of investigation. Histological work can examine their structural organization, while electrophysiological studies can assess related functional properties. The same preparations also support anatomical analysis and targeted experimental manipulation. Using one separation approach across these contexts can help connect microscopic structure with functional and translational questions in peripheral nerve research.
This technique is useful when investigators need access to individual bundles rather than the nerve as a single structure. Its applications include studying peripheral nerve anatomy, informing selective nerve repair and grafting, and examining how fascicular organization relates to functional pathways. It also contributes to neuroprosthetic research, where separated fascicles can serve as preparations for targeted investigation.
