Histology is the study of tissues. There are only four primary tissue types: epithelial, connective, muscular and neural. For now we will only concentrate on epithelial and connective tissues. Epithelial tissue covers exposed surfaces or lines internal cavities or passageways and forms glands.
The Cathedral of Learning in Bangkokâs Assumption University soars to a towering 522 feet (159 meters) in height. Built in 2002, the 39-story structure mimics the design of the University of Pittsburghâs Cathedral of Learning â albeit in a more postmodern style.
(Strassbourg Cathedral hit 470 feet in 1625, which is a bit higher than Cheops) (on preview I see I've been beaten to it, but the tower wasn't built until 1625, so there!) 1625 is the year that the Strasbourg Cathedral became the tallest building because a previous spire on another cathedral burnt down. It was completed however in 1439.
