Rigidity
rigidity[ri′jid·əd·ē] (astrophysics) The ratio of the momentum of a cosmic-ray particle to its electric charge, in units of the electron charge. (mechanics) The quality or state of resisting change in form. Rigidity the capability of a body or structure to resist deformation; a physicogeometric characteristic of the cross section of a structural element. In the case of simple deformations within the limits of Hooke’s law, rigidity is determined numerically as the product of the modulus of elasticity E (on elongation-contraction and on flexure) or G (on shear and torsion) and some geometric characteristic of the element cross section:EF on elongation-compression, El on flexure, GF on shear, and so on, where F is the cross section area, and I is the axial moment of inertia. The concept of rigidity is being widely used in the solution of problems concerning the strength of materials.
Rigidity in physiology, a functional state of the skeletal muscles, characterized by a marked increase in their tone and in their resistance to deformation. Muscle rigidity results from changes in the character of the neural influences that the central and peripheral nervous systems continuously exert to the muscles. An example of rigidity is decerebrate rigidity. In man, injuries and disturbances of the central nervous system and pathological irritation of the peripheral nerves give rise to various manifestations of muscle rigidity. Thus, poisoning by certain toxins, diseases of the nervous system, and hypnosis may cause a state of plastic tone, characterized by a waxlike condition of the muscles. In this state the extremities may easily be placed in any position and can remain thus, unchanged, for a prolonged period. Plastic tone characterizes a state of the nervous system called catalepsy, or plastic rigidity. rigidityThat property of a material which resists a change in its physical shape.rigidityi. The resistance offered by a body when under load. It is the ratio of the stress to the strain. Also known as stiffness ii. A property of a gyroscope by which its axis will remain in a fixed direction in space unless the rotor is acted upon by an external torque.rigidity
rigidity [rĭ-jid´ĭ-te] inflexibility or stiffness.clasp-knife rigidity increased tension in the extensor of a joint when it is passively flexed, giving way suddenly on exertion of further pressure; seen especially in upper motor neuron disease. Called also clasp-knife reflex.cogwheel rigidity tension in a muscle that gives way in little jerks when the muscle is passively stretched; seen in parkinson's disease.decerebrate rigidity see decerebrate rigidity.decorticate rigidity see decorticate rigidity.paratonic rigidity an intermittent abnormal increase in resistance to passive movement in a comatose patient.ri·gid·i·ty (ri-jid'i-tē), 1. Stiffness or inflexibility. See also: nuchal rigidity. Synonym(s): rigor (1) 2. In psychiatry and clinical psychology, an aspect of personality characterized by a person's resistance to change. See also: nuchal rigidity. 3. In neurology, one type of increase in muscle tone at rest; characterized by increased resistance to passive stretch, independent of velocity and symmetric about joints; increases with activation of corresponding muscles in the contralateral limb. Two basic types are cogwheel rigidity and lead-pipe rigidity. See also: nuchal rigidity. [L. rigidus, rigid, inflexible] rigidity Forensic pathology Rigor. See Rigor mortis Neurology Excessive muscle tone. See Extrapyramidal syndrome, Lead pipe rigidity, Parkinsonism Psychiatry An unreasonable resistance to change Vox populi Stiffness. ri·gid·i·ty (ri-jid'i-tē) 1. Stiffness or inflexibility. Synonym(s): rigor (1) . 2. psychiatry, clinical psychology An aspect of personality characterized by a person's resistance to change. 3. neurology One type of increase in muscle tone at rest; characterized by increased resistance to passive stretch, independent of velocity and symmetric about joints; increases with activation of corresponding muscles in the contralateral limb. Two basic types are cogwheel rigidity and leadpipe rigidity. See also: nuchal rigidity[L. rigidus, rigid, inflexible]rigidity Sustained muscle tension causing the affected part of the body to become stiff and inflexible. Rigidity may be due to muscle injury, neurological disease such as PARKINSON'S DISEASE, underlying inflammation as in PERITONITIS, or arthritis in an adjacent joint.
