Abnormal ocular alignment frequently results from damage to the intranuclear portion of the gaze system, including: cranial nerves (CN) III (oculomotor), IV (trochlear), and VI (abducens), or the myoneural
junction or extraocular muscles they innervate.
Combined involvement of muscle, nerve, and myoneural
junction following Leptospira infection.
Tetanospasmin then enters the nervous system peripherally at the myoneural
junction and is transported centripetally into neurons of the central nervous system (CNS).
In addition, the neonatal myoneural
junction appears to demonstrate an increased sensitivity to this class of agents.
(20) Initial bradycardia, bradypnea, and recumbency were likely related to effects of envenomation on vascular endothelium, peripheral nerve endings, and myoneural
junctions, (21) as opposed to an allergic or anaphylactic reactions, which generally demonstrate tachycardia.
