| familial periodic paralysis | <neurology> A rare inherited disorder, affecting men more often than women, characterised by intermittent episodes of muscle weakness or paralysis. One form, known as hypokalaemic periodic paralysis, is an autosomal recessive disorder that is characterised by bouts of muscle weakness (or paralysis) accompanied by low serum potassium levels. Inheritance: autosomal recessive. Incidence: 1 in 100,000. (27 Sep 1997) |

| Zenker's paralysis | Paresthesia and paralysis in the area of the external popliteal nerve. (05 Mar 2000) |
| faucial paralysis | Paralysis of the velum pendulum palati and the muscles forming the anterior pillars of the fauces. Synonym: faucial paralysis, isthmoplegia. Origin: G. Isthmos, isthmus, + paralysis (05 Mar 2000) |
| Klumpke's paralysis | A type of brachial birth palsy in which there is paralysis of the muscles of the distal forearm and hand (all ulnar innervated muscles, plus more distal radial and median-innervated muscles), due to a lesion of the lower trunk of the brachial plexus, or of the C8 and T1 cervical roots. Synonym: Dejerine-Klumpke palsy, Dejerine-Klumpke syndrome, Klumpke's paralysis. (05 Mar 2000) |
| flaccid paralysis | Paralysis with a loss of muscle tone. Compare: spastic diplegia. (05 Mar 2000) |
| lambing paralysis | A highly fatal metabolic disease of well-nourished ewes in the late stages of pregnancy, especially in ewes carrying twin lambs; it is caused by carbohydrate depletion of the blood and tissues, and is characterised by hypoglycaemia, ketonuria, fatty infiltration of the liver, rapid emaciation, coma, and a high death rate. Synonym: lambing paralysis, lambing sickness. (05 Mar 2000) |
| Landry's paralysis | <neurology, syndrome> Acute infective polyneuritis that results in a form of peripheral neuropathy with temporary loss of movement and sensation due to inflammation of multiple nerves and loss of myelin. The exact cause is unknown but has been associated with an abnormal immune response to viral infection, particularly cytomegalovirus infection, in which there is cell-mediated immunity to a component of myelin. The disease may be autoimmune in origin and complete recovery can take up to six months. Synonym: Guillain-Barre syndrome (12 Jul 2000) |
| fowl paralysis | See: avian lymphomatosis. (05 Mar 2000) |
| lead paralysis | Paralysis of the extensor muscles of the wrist causing wrist-drop; occurs in lead poisoning. Synonym: lead paralysis. (05 Mar 2000) |
| abducens nerve | <anatomy, nerve> The 6th cranial nerve. The abducens nerve originates in the abducens nucleus of the pons and sends motor fibres to the lateral rectus muscles of the eye. Damage to the nerve or its nucleus disrupts horizontal eye movement control. (12 Dec 1998) |
| abducent nerve | <anatomy> The abducent nerve enervates a muscle which moves the eyeball. Lesions of the sixth cranial nerve result in deviation of the eyeball outward and double vision. Synonym: cranial nerve VI. (27 Sep 1997) |
| accessory nerve | <anatomy, nerve> The accessory nerve enervates the sternocleidomastoid muscles and the trapezius muscles. Lesions of the eleventh result in drooping of the shoulder and inability to rotate the head away from the affected side. Synonym: cranial nerve XI. (27 Sep 1997) |
| accessory nerve lymph nodes | The nodes of the lateral deep cervical group that are located along the accessory nerve; their efferent vessels pass to the supraclavicular lymph nodes. Synonym: companion lymph nodes of accessory nerve, nodi lymphatici comitantes nervi accessorii. (05 Mar 2000) |
| accessory nerve trunk | Part of the accessory nerve formed within the cranial cavity by the union of the cranial and spinal roots, which then divides within the jugular foramen into internal and external branches, the former uniting with the vagus, the latter exiting the foramen as in independent branch which is commonly considered to be the accessory nerve. (05 Mar 2000) |
| accessory portion of spinal accessory nerve | <anatomy, nerve> The roots of the accessory nerve which arise from the medulla; the nerve fibres of the cranial root join the intracranial portion of the vagus nerve and are distributed to the pharyngeal plexus, providing the motor innervation of the soft palate (except the tensor veli palati) and the pharynx. Synonym: pars vagalis nervi accessorii, radices craniales, accessory portion of spinal accessory nerve, cranial roots, vagal part of accessory nerve, vagal part. (05 Mar 2000) |
