- n nerve A sinew, tendon, or other hard white cord of the body: the original meaning of the word, at the time when nervous tissue was not distinguished from some forms of connective tissue. See aponeurosis.
- n nerve In anatomy, a nerve-fiber, or usually a bundle of nerve-fibers, running from a central ganglionic organ to peripheral mechanisms, either active (as glands and muscles) or receptive (sense-organs). The nerve-fibers are bound together into a primitive bundle called a funiculus. The connective tissue between the fibers within the funiculus is the endoneurium, and the connective tissue sheathing the funiculus is the perineurium. In the larger nerves several funiculi may be bound together into one trunk by connective tissue which forms the epineurium. See cut under median.
