Earwax in the canal. Jaw movement assists this process by dislodging debris attached to the walls of the ear canal, increasing the likelihood of its expulsion. The lubrication provided by cerumen prevents desiccation of the skin within the ear canal. The lubricative properties arise from the high lipid content of the sebum produced by the sebaceous glands. In wet-type cerumen, these lipids include cholesterol, squalene, and many long-chain fatty acids and alcohols. While studies conducted up until the 1960s found little evidence supporting antibacterial activity for cerumen, more recent studies have found that cerumen has a bactericidal effect on some strains
Body farm of the forensic picture." Each stage of death is analyzed independently at the Body Farms to get a better understanding of the decomposition process on the body. Medical practitioners determine which insects or what climate cause human bodies to decompose the quickest, or in which manner they decompose according to differences in temperature or type of insect. The information regarding decomposed bodies is found to be important to the scientific community even if that information is found not necessarily in the bodies themselves, but the soil and plant life surrounding the bodies. Bryant, “has found grave importance in the soil
