(In the body) a whitish fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord, and impulses from these to the muscles and organs
the nerves that transmit pain
A poisonous vapor that rapidly disables or kills by disrupting the transmission of nerve impulses
(In invertebrates such as coelenterates and flatworms) a diffuse network of neurons that conducts impulses in all directions from a point of stimulus
= nerve ending.
= war of nerves.
A nerve which contains both sensory and motor nerve fibres.
A nerve carrying impulses from the brain or spinal cord to a muscle or gland
A substance that alters the functioning of the nervous system, typically inhibiting neurotransmission; especially one used as a weapon, a nerve gas.
The production of insensibility in a part of the body by injecting an anesthetic close to the nerves that supply it
A bony canal, especially of the skull, containing a nerve.
The major cord of nerve fibers running the length of an animal’s body, especially a ventral cord in invertebrates that connects segmental nerve ganglia
The axon of a neuron. A nerve is formed of a bundle of many such fibers, with their sheaths
Power ascribed to nerves; neuroelectric activity; an instance of this.
= nerve pathway.
A ring of nerves and ganglia encircling the pharynx in various invertebrates.
Anatomy. A bundle of nerve fibres as it emerges from the neuraxis; especially either of the paired (dorsal and ventral) bundles of nerve fibres that emerge from the spinal cord and unite to form a spinal nerve.
= nerve pathway.
A sudden burst of neural activity thought to be responsible for epilepsy, migraine, and certain other disorders (now historical).
A remedy thought to stimulate or benefit the nerves (also figurative).
A nerve tract.
A group or bundle of nerve fibres, especially in the central nervous system.
The main stem of a nerve
Embryology a neural tube.
Anatomy the retina (now historical).
Any of the small terminal branches of a nerve.
Each of the second pair of cranial nerves, transmitting impulses to the brain from the retina at the back of the eye
Each of twelve pairs of nerves that arise directly from the brain, not from the spinal cord, and pass through separate apertures in the skull
Each of the seventh pair of cranial nerves, supplying the facial muscles and the tongue
A sensory branch of the mandibular nerve that supplies the mucous membrane of the anterior part of the tongue and the floor of the mouth.
A nerve occupying a middle or midline position; specifically a main nerve of the forearm that arises from the medial and lateral cords of the brachial plexus.
A group of closely connected nerve cells that perform a particular function in the body; a ganglion
A nerve impulse.
A psychiatrist or psychoanalyst.
One of the fine branches at the end of a neuron, by which it makes contact either with another neuron or with a muscle or gland cell
A signal transmitted along a nerve fiber. It consists of a wave of electrical depolarization that reverses the potential difference across the nerve cell membranes
The route taken by a nerve impulse through the nervous system.
A patient suffering from a psychological or psychiatric disorder.
A naturally occurring or synthetic substance that disrupts the functioning of the nervous system; a neurotoxin, nerve agent, or nerve gas.
Causing stress or anxiety
A perineurium or endoneurium.
A nerve fibre.
The motor nerve serving each half of the diaphragm, which arises from the cervical plexus and also supplies sensory fibres to various mediastinal structures and to the serous surfaces of the diaphragm.
Anatomy and Zoology a large nerve arising from the brachial plexus and supplying branches to the skin and muscles of the posterior arm, forearm, and hand or manus.
A major nerve extending from the lower end of the spinal cord down the back of the thigh, and dividing above the knee joint. It is the nerve with the largest diameter in the human body
it's the waiting that's the most nerve-racking
Each of the sixth pair of cranial nerves, supplying the muscles concerned with the lateral movement of the eyeballs
