Possible definitions for neurones

neuron
Any of the cells of the nervous system. Sensory neurons relay information from sense organs, motor neurons carry impulses to muscles and glands, and interneurons transmit impulses between sensory and motor neurons. A typical neuron consists of dendrites (fibers that receive stimuli and conduct them inward), a cell body (a nucleated body that receives input from dendrites), and an axon (a fiber that relays the nerve impulse from the cell body outward to its terminals, the synaptic knobs). Both axons and dendrites may be referred to as nerve fibers. Impulses are conducted by neurotransmitter chemicals released by the axon's synaptic knobs across the synapses (junctions between neurons, or between a neuron and an effector cell, such as a muscle cell) or, in some cases, pass directly from one neuron to the next. Most neurons are insulated by a myelin sheath formed by cells (Schwann cells) surrounding the axons. Bundles of fibers from neurons held together by connective tissue form nerves.


neurosis
Mental and emotional disorder that affects only part of the personality, is accompanied by a less distorted perception of reality than in a psychosis, and is characterized by various physiological and mental disturbances (such as visceral symptoms and impaired concentration). The neuroses include anxiety attacks, certain forms of depression, hypochondriasis, hysterical reactions, obsessive-compulsive disorders, phobias, various sexual dysfunctions, and some tics. They have traditionally been thought to be based on emotional conflict in which a blocked impulse seeks expression in a disguised response or symptom. Behavioral psychologists regard them as learned, inappropriate responses to stress, which can be unlearned.
