1 Scientists believe this powerful predator could eat up to 500 pounds (230 kilograms) of meat in one bite. 2  Fossils of T. rex prey, including Triceratops and Edmontosaurus, suggest T. rex crushed and broke bones as it ate, and bone fragments have been found in its dung.
Etiology. Infection is the principal cause of tympanic membrane perforation (TMP). Acute infection of the middle ear may cause a relative ischemia in the drum concurrent with increased pressure in the middle ear space.This leads to a tear or rupture of the eardrum that is usually preceded by severe pain. If the perforation does not heal, it leaves a residual tympanic membrane perforation (TMP).nfection is the principal cause of tympanic membrane perforation (TMP). Acute infection of the middle ear may cause a relative ischemia in the drum concurrent with increased pressure in the middle ear space.
Body temperature is usually measured by a thermometer placed in the mouth, the rectum, or the auditory canal (for tympanic membrane temperature). The normal oral temperature is 37Â° Celsius (98.6Â° Fahrenheit); rectally, it is 37.3Â° Celsius (99.2Â° Fahrenheit).The tympanic membrane temperature is a direct reflection of the body's core temperature. These values are based on a statistical average.xillary temperature is usually from 0.5Â° F to 1Â° F lower than the oral temperature. Rectal temperatures may be 0.5Â° F to 1Â° F higher than oral readings. Body temperature appears to vary 1Â° F to 2Â° F throughout the day, with lows recorded early in the morning and peaks between 6 pm and 10 pm.
