| nerve | 1. <anatomy> One of the whitish and elastic bundles of fibres, with the accompanying tissues, which transmit nervous impulses between nerve centers and various parts of the animal body. An ordinary nerve is made up of several bundles of nerve fibres, each bundle inclosed in a special sheath (the perineurium) and all bound together in a connective tissue sheath and framework (the epineurium) containing blood vessels and lymphatics. 2. A sinew or a tendon. 3. Physical force or steadiness; muscular power and control; constitutional vigor. "he led me on to mightiest deeds, Above the nerve of mortal arm." (Milton) 4. Steadiness and firmness of mind; self-command in personal danger, or under suffering; unshaken courage and endurance; coolness; pluck; resolution. 5. Audacity; assurance. 6. <botany> One of the principal fibrovascular bundles or ribs of a leaf, especially when these extend straight from the base or the midrib of the leaf. 7. <zoology> One of the nervures, or veins, in the wings of insects. <anatomy> Nerve cell, the operation of stretching a nerve in order to remedy diseases such as tetanus, which are supposed to be influenced by the condition of the nerve or its connections. Origin: OE. Nerfe, F. Nerf, L. Nervus, akin to Gr. Sinew, nerve; cf. String, bowstring; perh. Akin to E. Needle. Cf. Neuralgia. Source: Websters Dictionary (01 Mar 1998) |
| nerve avulsion | The tearing away of a peripheral nerve at its point of origin from its parent nerve due to traction. (05 Mar 2000) |
| nerve biopsy | <investigation, procedure, surgery> A procedure which involves the removal of a small specimen of nerve tissue for microscopic analysis. The ankle or wrist are the most common sites used for nerve biopsy. Conditions such as amyloidosis, sarcoidosis, metabolic polyneuropathy, leprosy, demyelination, alcoholic neuropathy, Charcot-Marie-tooth disease, peroneal nerve dysfunction, mononeuritis multiplex and other polyneuropathies may be detected using this study. (21 Mar 1998) |
| nerve block | Interruption of the conduction of impulses in peripheral nerves or nerve trunks by the injection of a local anaesthetic solution. (12 Dec 1998) |
| nerve block anaesthesia | Conduction anaesthesia in which local anaesthetic solution is injected about nerves, nerve trunks, or nerve plexuses. (05 Mar 2000) |
| nerve cell | An excitable cell specialised for the transmission of electrical signals over long distances. Neurons receive input from sensory cells or other neurons and send output to muscles or other neurons. Neurons with sensory input are called sensory neurons, neurons with muscle outputs are called motoneurons, neurons that connect only with other neurons are called interneurons. Neurons connect with each other via synapses. Neurons can be the longest cells known, a single axon can be several metres in length. Although signals are usually sent via action potentials, some neurons are nonspiking. (18 Nov 1997) |
| nerve cell body | The part of the neuron that includes the nucleus but excludes the processes. (05 Mar 2000) |
| nerve compression syndromes | Repeated or prolonged pressure on a nerve root or peripheral nerve leading to ischemia, the response to which is oedema above and below the source of pressure. If the pressure is not relieved, fibrosis tends to develop. Types of nerve compression syndromes are the neuropathy caused by intervertebral disk herniation, compression of the median nerve in the carpal tunnel, compression of the ulnar nerve in the elbow, and compression of the lateral cutaneous nerve of the thigh in meralgia paresthetica. This is also called pressure neuropathy. (12 Dec 1998) |
| nerve conduction | The transmission of an impulse along a nerve fibre. (05 Mar 2000) |
| nerve conduction velocity | The rate of impulse conduction in a peripheral nerve or its various component fibres, generally expressed in meters per second. (05 Mar 2000) |
