Which of the following is a correct statement about a simple epithelium? a. All of the cells are in direct contact with the basement membrane. b. It protects against mechanical abrasion. c. It is formed from multiple layers of cells. d. It may contain the protein keratin.
Botox is a toxin produced by the bacterium Clostridium botulinum. When ingested with tainted food, Botox can kill by paralyzing muscles needed for breathing and heartbeat. Physicians inject small quantities of diluted Botox into facial muscles to paralyze them and reduce the appearance of wrinkles. Some people have expressed concern about a trend in which people come together for “Botox parties” at hair salons and other nonmedical settings. What are the risks of getting injections in such a setting?
