paralysis

loss or impairment of motor function in a part due to a lesion of the neural or muscular mechanism; also, by analogy, impairment of sensory function (sensory paralysis). Called also palsy. Motor paralysis may be expressed as flaccid, in the case of lower motor neuron lesion, or spastic, in the case of an upper motor neuron lesion. See also paraplegia, quadriplegia, hemiplegia and paralyses of individual cranial and peripheral nerves.

paralysis of accommodation
paralysis of the ciliary muscles of the eye so as to prevent accommodation.
anal paralysis
manifested by flaccidity and lack of tone of the anal sphincter, and loss of house training restraint in companion animals.
antepartum paralysis
pressure on sciatic nerves by a large fetus in late pregnancy in a cow can cause posterior paralysis that is cured by a cesarean section.
ascending paralysis
spinal paralysis that progresses forwards involving first the hindlimbs then the forelimbs, then the intercostal muscles, then the diaphragm, and finally the muscles of the neck.
birth paralysis
that due to injury received by the neonate at birth.
bladder paralysis
manifested by fullness of the bladder and response to manual pressure. See also motor paralytic urinary bladder.
cage paralysis
see thiamin nutritional deficiency.
central paralysis
any paralysis due to a lesion of the brain or spinal cord.
cerebral paralysis
paralysis caused by some intracranial lesion.
Chastek paralysis
see thiamin nutritional deficiency.
compression paralysis
that caused by pressure on a nerve.
congenital paralysis
paralysis of the newborn. Many cases are due to birth trauma especially when lay persons exert excessive traction. Other causes are enzootic ataxia, inherited congenital paraplegias in calves and pigs, spina bifida and spinal dysraphism and occipito-alanto-axial malformations in foals and puppies.
conjugate paralysis
loss of ability to perform some parallel ocular movements.
coonhound paralysis
see idiopathic polyradiculoneuritis.
crossed paralysis
paralysis affecting one side of the head and the other side of the body.
curled toe paralysis
a disease of poultry caused by a nutritional deficiency of riboflavin. See also curled toe paralysis.
decubitus paralysis
paralysis due to pressure on a nerve from lying for a long time in one position.
esophageal paralysis
manifested by inability to swallow, and regurgitation.
facial paralysis
weakening or paralysis of the facial nerve. See also facial paralysis.
flaccid paralysis
paralysis characterized by loss of voluntary movement, decreased tone of limb muscles, absence of tendon reflexes and neurogenic atrophy.
immunological paralysis
the absence of immune response to a specific antigen. See also tolerance.
infectious bulbar paralysis
ischemic paralysis
local paralysis due to stoppage of circulation.
lambing paralysis
maternal obstetric paralysis in the ewe.
laryngeal paralysis
see laryngeal hemiplegia.
mixed paralysis
combined motor and sensory paralysis.
motor paralysis
paralysis of the voluntary muscles.
nerve paralysis
paralysis caused by damage to the local motor nerve supply. See also peripheral nerve paralysis (below).
obstetric paralysis
see maternal obstetric paralysis.
partial paralysis
see paresis.
peripheral nerve paralysis
the part deprived of its peripheral nerve supply shows flaccid paralysis, absence of spinal reflexes, muscle atrophy and a subnormal temperature.
postcalving paralysis
see maternal obstetric paralysis.
posterior paralysis
paralysis of the hindlimbs, tail and perineum. See also paraplegia.
range paralysis
sensory paralysis
loss of sensation resulting from a morbid process.
spastic paralysis
paralysis with rigidity of the muscles and heightened deep muscle reflexes.
tongue paralysis
see hypoglossal nerve paralysis.
