10. G,H

analgesia

lack of sensitivity to pain

motor aphasia

difficulty in speaking (patient cannot articulate words but can understand speech and knows what she or he wants to say)

paresis

weakness and partial loss of movement

quadriplegia

paralysis in all four extremities (damage is to the cervical part of the spinal cord)

asthenia

no strength (weakness)

comatose

pertaining to coma (loss of consciousness from which the patient cannot be aroused)

paresthesia

condition of abnormal sensations (prickling, tingling, burning)

hyperkinesis

excessive movement

anesthesia

condition of no sensation or nervous feeling

causalgia

severe burning pain from injury to peripheral nerves

akinetic

pertaining to without movement

hypalgesia

diminished sensation to pain

dyskinesia

impairment of the ability to perform voluntary movements

migraine

recurrent vascular headache with severe pain of unilateral onset and photophobia (sensitivity to light)

multiple sclerosis

Destruction of myelin sheath (demyelination) and its replacement by hard plaques

epilepsy

Sudden, transient disturbances of brain function cause seizures

myelomeningocele

The spinal column is imperfectly joined (a split in a vertebra occurs), and part of the meninges and spinal cord can herniate out of the spinal cavity

amyotrophic lateral sclerosis

Atrophy of muscles and paralysis caused by damage to motor neurons in the spinal cord and brainstem

Huntington disease

Patient displays bizarre, abrupt, involuntary, dance-like movements, as well as decline in mental functions

hydrocephalus

Cerebrospinal fluid accumulates in the head (in the ventricles of the brain)

myasthenia gravis

Loss of muscle strength due to the inability of a neurotransmitter (acetylcholine) to transmit impulses from nerve cells to muscle cells

Parkinson disease

Degeneration of nerves in the basal ganglia occurring in later life, leading to tremors, shuffling gait, and muscle stiffness; dopamine (neurotransmitter) is deficient in the brain

Alzheimer disease

Deterioration of mental capacity (dementia); autopsy shows cerebral cortex atrophy, widening of cerebral sulci, and microscopic neurofibrillary tangles

Bell palsy

Unilateral facial paralysis
