paralysis, pl. paralyses (pa-ral´i-sis, -sez)
1. Loss of power of voluntary movement in a muscle through injury to or disease of its nerve supply. 2. Loss of any function, as sensation, secretion, or mental ability. [G. fr. para- + lysis, a loosening]
acute ascending p. a p. of rapid course beginning in the legs and involving progressively the trunk, arms, and neck, ending sometimes in death in from one to three weeks.ascending p;

p. ag´itans obsolete term for parkinsonism (1) .

central p. p. due to a lesion in the brain or spinal cord.

compression p. p. due to external presure on a nerve.
coonhound p. a polyradiculoneuritis of dogs (especially raccoon-hunting breeds) following a raccoon bite and characterized by weakness, hindlimb hyporeflexia, and a flaccid symmetrical tetraplegia.
crossed p. alternating hemiplegia
crutch p. a form of pressure p. affecting the arm, and caused by compression of the brachial plexus or radial nerve by the crosspiece of a crutch.crutch palsy;

Erb p. Erb palsy
Erb spinal p. chronic myelitis of syphilitic origin.
facial p. paresis or p. of the facial muscles, usually unilateral, due to either 1) a lesion involving either the nucleus or the facial nerve peripheral to the nucleus (peripheral facial paralysis), or 2) a supranuclear lesion in the cerebrum or upper brainstem (central facial paralysis); with the latter, facial weakness is usually partial and the upper portion of the face is relatively spared, due to bilateral cortical connections.facial palsy, facioplegia, fallopian neuritis, prosopoplegia;
familial periodic p. one of the inherited muscle disorders manifested as recurrent episodes of marked generalized weakness. See hyperkalemic periodic p., hypokalemic periodic p., normokalemic periodic p.

Gubler's p. Gubler's syndrome
hyperkalemic periodic p. a form of periodic p. in which the serum potassium level is elevated during attacks; onset occurs in infancy, attacks are frequent but relatively mild, and myotonia is often present; autosomal dominant inheritance.
hypokalemic periodic p. [type I MIM 17066, *170600, *311700] a form of periodic p. in which the serum potassium level is low during attacks; onset usually occurs between the ages of 7 and 21 years; attacks may be precipitated by exposure to cold, high carbohydrate meal, or alcohol, may last hours to days, and may cause respiratory p.; autosomal dominant or X-linked inheritance.
hysterical p. a psychosomatic numbness of a limb sometimes to the point of p. See hysteria.
immune p. the induction of tolerance in mice due to injection of large amounts of polysaccharide. The polysaccharide is poorly metabolized and the p. remains only during the persistence of the above.
immunological p. lack of specific antibody production after exposure to large doses of the antigen; immunological p. disappears when the antigen is eliminated. See also immunologic tolerance.

motor p. loss of the power of muscular contraction.
musculospiral p. p. of the muscles of the forearm due to injury of the radial (musculospiral) nerve.
myogenic p. acute anterior poliomyelitis
normokalemic periodic p. [type III MIM 170600] a form of periodic p. in which the serum potassium level is within normal limits during attacks; onset usually occurs between the ages of 2 and 5 years; there is often severe quadriplegia, usually improved by the administration of sodium salts; autosomal dominant inheritance.sodium-responsive periodic p;
obstetrical p. obstetrical palsy
ocular p. p. of extraocular and intraocular muscles.
parturient p. milk fever (2)
periodic p. term for a group of diseases characterized by recurring episodes of muscular weakness or flaccid p. without loss of consciousness, speech, or sensation; attacks begin when the patient is at rest, and there is apparent good health between attacks. See hyperkalemic periodic p., hypokalemic periodic p., normokalemic periodic p.
