Observations on the sensory nature of the intramuscular nerve action potential.
The nature and the origin of the small pre-potential wave which can be recorded immediately before the main muscle action potential on indirect stimulation was studied in the median nerve of 12 normal subjects. It is considered to be a sensory antidromic response recorded from the large afferent fibres which innervate the thumb because it was recorded in all 12 subjects, and the threshold was a...
متن کاملCompound Nerve Action Potential of Common Peroneal Nerve and Sural Nerve Action Potential in Common Peroneal Neuropathy
To enhance the accuracy for determining the precise localization, the findings of the compound nerve action potentials (CNAPs) of the common peroneal nerve (CPN) were investigated in patients with common peroneal mononeuropathy (CPM) in the knee, and the sural sensory nerve action potentials (SNAPs) were also analyzed. Twenty-five patients with CPM in the knee were retrospectively reviewed. The...
متن کاملHistopathological effects of intramuscular metamizole sodium on rat sciatic nerve
Objective(s): We investigated the histopathological effects of metamizole sodium (MS) on the sciatic nerve. Materials and Methods: This study was performed using 48 adult male Wistar albino rats. Ten groups were constituted with 6 rats in each group. MS injection into the sciatic nerve (group 1), MS injection into the muscle [group 3 (50 mg/kg, 0.4 ml) and group 5 (50 mg/kg, 0.8 ml)], MS injec...
متن کاملMeasurement of the action potential of myelinated nerve fiber.
THE PEAK VALUE of the action potential of the vertebrate myelinated fiber has been previously recorded by a number of investigators. (1-5 and others). Values range from about 60-155 mv depending on the method employed. These methods may be divided into three general categories. The action potential at the node of a single fiber may be estimated from a knowledge of the action current in the axis...
