| involuntary nervous system | <anatomy> Neurons that are not under conscious control, comprising two antagonistic components, the sympathetic and parasympathetic nervous systems. The autonomic nervous system regulates key functions including the activity of the cardiac (heart) muscle, smooth muscles (e.g., of the gut), and glands. The autonomic nervous system has two divisions: 1. The sympathetic nervous system that accelerates the heart rate, constricts blood vessels, and raises blood pressure. 2. The parasympathetic nervous system slows the heart rate, increases intestinal and gland activity, and relaxes sphincter muscles. (03 Jul 1999) |

| involve | 1. To roll or fold up; to wind round; to entwine. "Some of serpent kind . . . Involved Their snaky folds." (Milton) 2. To envelop completely; to surround; to cover; to hide; to involve in darkness or obscurity. "And leave a singed bottom all involved With stench and smoke." (Milton) 3. To complicate or make intricate, as in grammatical structure. "Involved discourses." 4. To connect with something as a natural or logical consequence or effect; to include necessarily; to imply. "He knows His end with mine involved." (Milton) "The contrary necessarily involves a contradiction." (Tillotson) 5. To take in; to gather in; to mingle confusedly; to blend or merge. "The gathering number, as it moves along, Involves a vast involuntary throng." (Pope) "Earth with hell To mingle and involve." (Milton) 6. To envelop, infold, entangle, or embarrass; as, to involve a person in debt or misery. 7. To engage thoroughly; to occupy, employ, or absorb. "Involved in a deep study." 8. <mathematics> To raise to any assigned power; to multiply, as a quantity, into itself a given number of times; as, a quantity involved to the third or fourth power. Imply is opposed to express, or set forth; thus, an implied engagement is one fairly to be understood from the words used or the circumstances of the case, though not set forth in form. Involve goes beyond the mere interpretation of things into their necessary relations; and hence, if one thing involves another, it so contains it that the two must go together by an indissoluble connection. War, for example, involves wide spread misery and death; the premises of a syllogism involve the conclusion. Synonym: To imply, include, implicate, complicate, entangle, embarrass, overwhelm. Origin: L. Involvere, involutum, to roll about, wrap up; pref. In- in + volvere to roll: cf. OF. Involver. See Voluble, and cf. Involute. (28 Oct 1998) |
