Animal Physiology

Eukaryotic microorganisms possess membrane-bound cell organelles and include fungi and protists , whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea. Viruses have been variably classified as organisms, [5] as they have been considered either as very simple microorganisms or very complex molecules. Prions , never considered as microorganisms, have been investigated by virologists, however, as the clinical effects traced to them were originally presumed due to chronic viral infections, and virologists took search—discovering "infectious proteins". The existence of microorganisms was predicted many centuries before they were first observed, for example by the Jains in India and by Marcus Terentius Varro in ancient Rome. The first recorded microscope observation was of the fruiting bodies of moulds, by Robert Hooke in , but the Jesuit priest Athanasius Kircher was likely the first to see microbes, which he mentioned observing in milk and putrid material in

Atropine is a medication used to treat certain types of nerve agent and pesticide poisonings as well as some types of slow heart rate and to decrease saliva production during surgery. Common side effects include a dry mouth, large pupils , urinary retention , constipation , and a fast heart rate. Atropine occurs naturally in a number of plants of the nightshade family including deadly nightshade , Jimson weed , and mandrake. Topical atropine is used as a cycloplegic , to temporarily paralyze the accommodation reflex , and as a mydriatic , to dilate the pupils. In refractive and accommodative amblyopia , when occlusion is not appropriate sometimes atropine is given to induce blur in the good eye. While atropine eye drops have been shown to be effective in slowing the progression of myopia in children in several studies, side effects such as blurred vision and sensitivity to light occur. Atropine was previously included in international resuscitation guidelines for use in cardiac arrest associated with asystole and PEA , but was removed from these guidelines in due to a lack of evidence for its effectiveness.
