v.c.1500, “to ornament with threads;” see nerve (n.). Meaning “to give strength or vigor” is from 1749. Related: Nerved; nerving. n.late 14c., nerf “sinew, tendon,” from Old French nerf and directly from Medieval Latin nervus “nerve,” from Latin nervus “sinew, tendon; cord, bowstring,” metathesis of pre-Latin *neuros, from PIE *(s)neu- “tendon, sinew” (cf. Sanskrit snavan- “band, sinew,” Armenian neard “sinew,” Greek neuron “sinew, tendon,” in Galen “nerve”). Sense of “fibers that convey impulses between the brain and the body” is from c.1600. Secondary senses developed from meaning “strength, vigor, energy” (c.1600), from the “sinew” sense. Hence figurative sense of “feeling, courage,” first attested c.1600; that of “courage, boldness” is from 1809; bad sense “impudence, cheek” is from 1887. Latin nervus also had a figurative sense of “vigor, force, power, strength,” as did Greek neuron. From the neurological sense come Nerves “condition of nervousness,” attested from 1792; to get on someone’s nerves, from 1895. War of nerves “psychological warfare” is from 1915. n.
- Any of the cordlike bundles of nervous tissue made up of myelinated or unmyelinated nerve fibers and held together by a connective tissue sheath through which sensory stimuli and motor impulses pass between the brain or other parts of the central nervous system and the eyes, glands, muscles, and other parts of the body.
- The sensitive tissue in the pulp of a tooth.
- nerves Nervous agitation caused by fear, anxiety, or stress.
- Any of the bundles of fibers made up of neurons that carry sensory and motor information throughout the body in the form of electrical impulses. Afferent nerves carry information to the central nervous system, and efferent nerves carry information from the central nervous system to the muscles, organs, and glands. Efferent nerves include the nerves of the peripheral nervous system, which control voluntary motor activity and of the autonomic nervous system, which controls involuntary motor activity.
A bundle of fibers composed of neurons that connects the body parts and organs to the central nervous system and carries impulses from one part of the body to another. see bundle of nerves; get on someone’s nerves; get up (one’s nerve); have a nerve; lose one’s nerve; of all the nerve; war of nerves.
