Nerva–Antonine dynasty

The Nerva–Antonine dynasty (96–192 ce) ruled Rome through Nerva, Trajan, Hadrian, Antoninus Pius, Marcus Aurelius, Lucius Verus, and Commodus; mostly adoptive succession, called the five good emperors era, ending in civil war.

Nerve

Nerve: a bundle of axon fibers carrying chemical and electrical messages between the body and the brain. Peripheral fibers measure 0.2–18 micrometers; myelinated fibers conduct fastest and regrow about 1 mm/day after injury.

Nerve (2016 film)

Nerve is a 2016 American techno-thriller directed by Henry Joost and Ariel Schulman, in which high school senior Vee joins an online dare game with dangerous dares, starring Emma Roberts and Dave Franco.

Nerve ablation

Nerve ablation is a procedure that destroys nerve tissue with heat or chemicals to interrupt pain. It is used to target chronic joint and back pain.

Nerve agent

A nerve agent, also called nerve gas, is an organophosphorus chemical warfare agent that kills by inhibiting acetylcholinesterase; agents include sarin, tabun, soman, and VX.

Nerve block

Nerve block: injection of medication near a nerve or nerve group for pain relief, diagnosis, or surgical anesthesia. Also regional anesthesia; first performed by Halsted with cocaine in 1884; includes epidural, Bier, and peripheral blocks.

Nerve compression syndrome

Nerve compression syndrome, or entrapment neuropathy, is pressure on a peripheral nerve at anatomical tunnels, causing pain, numbness, and weakness. Carpal tunnel syndrome is the most common type; cubital tunnel is second.

Nerve conduction study

Nerve conduction study (NCS), also called nerve conduction velocity test, is an electrodiagnostic test stimulating peripheral nerves to measure latency, amplitude, and conduction velocity, used with EMG to diagnose neuropathy and compression syndromes like carpal tunnel.

Nerve conduction velocity

Nerve conduction velocity (NCV), also called a nerve conduction study (NCS), measures how fast electrical signals travel along peripheral nerves using surface electrodes. Covers Helmholtz's 1870 measurement, temperature and age effects, diagnostic thresholds, and AANEM standards.

Nerve crush

Nerve crush is a surgical technique that deliberately compresses a peripheral nerve to interrupt axons while preserving the connective tissue sheaths, producing a standardized axonotmesis used to study nerve regeneration.

Nerve Expansion

Nerve expansion (nerve lengthening, nerve stretching): MeSH-defined procedures that gradually elongate nerves to repair nerve tissue; experimental tissue-expander and fixator methods, not yet standard treatment.

Nerve field stimulation

Nerve field stimulation (NFS), usually called peripheral nerve field stimulation (PNFS), is a neuromodulation technique for chronic pain in which leads are implanted in the painful area itself.

Nerve grafting

Nerve grafting is a plastic and reconstructive surgery technique that bridges gaps in injured peripheral nerves with donor nerve segments, most often the patient's own sural nerve, so regenerating axons can cross the defect.

Nerve growth factor

Nerve growth factor (NGF), the first discovered neurotrophin, found by Levi-Montalcini and Hamburger in the 1950s; signals via TrkA and p75NTR; basis for cenegermin (neurotrophic keratitis) and anti-NGF pain drugs.

NERVE study

NERVE study (NCT07259382), Neuro-Inflammation in Extremity Trauma: Risk Verification in Elbow Trauma, a Université de Montréal prospective cohort of 60 elbow fracture patients measuring neuro-inflammation biomarkers against pain, opioid use, and function.

Nerve transfer

A nerve transfer, also called nerve transfers, is surgery that connects a functioning donor nerve to an injured nerve, restoring motor function or protective sensation.

Nerve-sparing prostatectomy

Nerve-sparing prostatectomy, or nerve-sparing radical prostatectomy, is a surgical technique for radical prostatectomy that preserves the nerves alongside the prostate, reducing erectile dysfunction and incontinence without compromising cancer control.

Nerviano Medical Sciences

Nerviano Medical Sciences is an Italian clinical-stage oncology biopharmaceutical company based in Nerviano, near Milan, which develops small-molecule cancer therapies, principally kinase inhibitors, including onvansertib licensed to Cardiff Oncology.

NERVO

NERVO are Australian twin sisters Miriam and Olivia Nervo of Melbourne, an EDM and electro-house DJ and production duo. They co-wrote the Grammy-winning "When Love Takes Over", released the 2015 album Collateral, and ranked as high as #16 in DJ Mag's top 100.

Nervonic acid

Nervonic acid is a monounsaturated very long-chain fatty acid that is a structural component of myelin in the mammalian central nervous system and is richest in Malania oleifera seed oil.

Nervous Conditions

Nervous Conditions is a 1988 novel by Zimbabwean writer Tsitsi Dangarembga about a girl's education in 1960s Rhodesia, and the first novel published in English by a Black Zimbabwean woman.

Nervous network (BEAM robotics)

A nervous network in BEAM robotics is an analog control circuit of simple electronic neurons that replaces the microprocessor in a robot, invented by Mark W. Tilden.

Nervous system

The nervous system is the body's network of nerve tissue that transmits signals between the brain, spinal cord, and the rest of the body, controlling movement, breathing, and thought.

Nervous system and sensory organs of bivalves

The nervous system and sensory organs of bivalves lack a brain, using three paired ganglia, statocysts in the foot, and eyes, including scallops' mirror eyes.

Nervous system development

Nervous system development: the process building the nervous system, from neural induction (Spemann-Mangold 1924, BMP blockade) and human neurulation at 2-3 weeks post-conception through neurogenesis, patterning, and organoid models of neurodevelopmental disorders.

Nervous system of earthworms

The earthworm nervous system has a bilobed brain, a circumpharyngeal ring, and a double ventral nerve cord with ganglia in each segment, supporting escape reflexes and regeneration.

Nervous tissue

Nervous tissue, also called neural tissue, is the excitable tissue of the nervous system composed of neurons and glial cells (neuroglia), with six glial types across CNS and PNS, myelin from oligodendrocytes and Schwann cells, and the neuron doctrine of Cajal and Golgi as its foundation.

Nervous Young Man

Nervous Young Man is the eighth self-released Car Seat Headrest album, put out by Will Toledo on Bandcamp on August 23, 2013. A conceptual double album of songs written between ages 17 and 21, it includes the long tracks Boxing Day and The Gun Song and the Disjecta Membra outtakes companion.
