T or F: Buccal mucosa is not keratinized under normal conditions.....
What is TRUE
T or F: Tonsils produce lymphocytes which help fight infection, and may transform into plasma cells.….

TRUE!
T or F: Langerhan cells are located in the Stratum Spinosm……
TRUE!!
These cells function in processing antigenic material. They make contact with invading bacteria and establish a response mechanism to protect the body.
