Both the degree of myelination and the presence of excitatory amino acid binding sites also may play a role in the pathophysiology of tissue damage. 6 The primary lesions seen on autopsy in term newborns are in the cortex and basal ganglia ( Fig. 1 ). [glowm.com]
The pathophysiology of the condition relates to a disturbance in neuromuscular transmission at the myoneural junction (motor endplate) of skeletal muscle (Figure). [healio.com]
