Neurophysiological effects of methyl mercury on the nervous system. 1982

Y Murai, and S Shiraishi, and Y Yamashita, and A Ohnishi, and K Arimura

There was electrophysiological and histological evidence of axonal degeneration in sural nerves of rats with methyl mercury intoxication. In monkeys, there was no sensory nerve involvement, whereas somatosensory and visual evoked potentials showed progressive slowing of their major peaks in the course of the intoxication. Pathological changes were confined to the calcarine cortex. The possibility of sensory nerve involvement in patients with organic mercury poisoning was discussed.

D008475 Median Nerve A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand.

D001921 Brain The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM. Encephalon

D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013979 Tibial Nerve The medial terminal branch of the sciatic nerve. The tibial nerve fibers originate in lumbar and sacral spinal segments (L4 to S2). They supply motor and sensory innervation to parts of the calf and foot.
