Myelinated retinal nerve fibers

The Pan African Medical Journal, 2014
A 7-year-old girl of second degree consanguineous parents, presented with an 8 months history of intermittent exotropia of the left eye. Cycloplegic refraction was -0.25.-0.50,165 and -3.00.-0.50,20, in the right and left eyes respectively.

Whole-Mount Immunostaining for the Visual Separation of A- and C-Fibers in the Study of the Sciatic Nerve [PDF]

Bio-Protocol
Peripheral nerve injuries (PNIs) often result in incomplete functional recovery due to insufficient or misdirected axonal regeneration. Balanced regeneration of myelinated A-fibers and unmyelinated C-fibers is essential for functional recovery, making it

Gallyas Silver Impregnation of Myelinated Nerve Fibers

Bio-Protocol, 2019
In the nervous system of vertebrates, nerve impulse propagation is accelerated by the ensheathment of neuronal axons with myelin. Myelin sheaths are molecularly specialized, lipid-rich plasma membrane extensions of Schwann cells in the peripheral nervous

Optical Modeling and Characterization of Demyelinated Nerve Using Graphene-Based Photonic Structure

IEEE Access, 2022
The myelin sheath, as an insulation layer in nerve cells, plays an essential role in neural communication and signal conduction. Loss of myelin, referred to as demyelination, is associated with many mental disorders. Detecting the tiny demyelinated parts

Enlargement of the Nerve Fibers of Silenced Lumbosacral Motoneurons in Cats

Biomedicines, 2022
Whether neuromuscular activity influences the size of motor nerves is controversial. All neuromuscular activity in cat hindlimbs was eliminated by spinal cord isolation (SCI), namely, spinal cord transection above and below the medial gastrocnemius (MG ...
