Monkeys are haplorhine (dry-nosed) primates, a paraphyletic group generally possessing tails and consisting of approximately 260 known living species. Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons.he New World monkeys and the Old World monkeys are each monophyletic groups, but their combination is not, since it excludes hominoids (apes and humans). Thus the term monkey no longer refers to a recognized scientific taxon.

Myasthenia gravis is a disease in which antibodies directed at nicotinic acetylcholine receptors are produced, leading to a deficiency of acetylcholine receptors at the neuromuscular junction.This results in impairment of muscular excitation, which appears clinically as fatigable muscle weakness.yasthenia gravis affecting one or a combination of the extraocular muscles without ptosis is less common; however, cases such as bilateral internuclear ophthalmoplegia without ptosis have been described in the literature.
