The Furcal Nerve Revisited

Atypical sciatica and discrepancy between clinical presentation and imaging findings is a dilemma for treating surgeon in management of lumbar disc herniation. It also constitutes ground for failed back surgery and potential litigations thereof. Furcal nerve (Furcal = forked) is an independent nerve with its own ventral and dorsal branches (rootlets) and forms a link nerve that connects lumbar ...

Reply to: The Furcal Nerve Revisited

They reported It is formed by ventral and dorsal rami of L1-L4 nerve roots with contribution from 12th thoracic nerve (i.e. subcostal nerve). After the anterior rami of the upper four lumbar nerves have supplied psoas and quadratus lumborum segmentally, they form the pleksus in the substance of psoas major.2,3 Juliana Farny et al. reported The lumbar plexus originated from the first four lumbar...

Inferior Alveolar Nerve Block Revisited.

Teaching nerve conduction to undergraduates: the "traveling flame" analogy revisited.

A familiar analogy to the propagation of the electric wave in a nerve lies in the burning of a cigarette. This analogy, which has persisted through several editions of popular textbooks of physiology, has never been elaborated beyond a cursory mention. In this article, the analogy is reinvoked and refined to explain the cable properties of nerve, saltatory conduction, and some other factors aff...

QUICKSELECT Revisited

We give an overview of the running time analysis of the random divide-and-conquer algorithm FIND or QUICKSELECT. The results concern moments, distribution of FIND’s running time, the limiting distribution, a stochastic bound and the key: a stochastic fixed point equation.
