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.
A cathedral is defined as a church featuring a cathedra, or bishops chair, to which local parishes report in as a sort of regional headquarters. The world's largest religious structure is St. Peter's Basilica in Rome, but it is too big - ironically - and too universal to be considered a cathedral. Which leaves the Cathedral Church of St. John the Divine. It is the focal point for the Episcopal church in New York, and therefore a true cathedral. Measuring in at 121,000 square feet or the size of two football fields, (with room left over for the football) it is properly placed at the top of many 'World's Largest Cathedrals lists.
