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.
Above the crossing, rising just over 300 feet above grade, is the Gloria in Excelsis Tower. The Cathedral is the sixth largest in the world, second largest in the United States. The top of the tower is the highest point in DC. The one story porch projecting from the south transept has a large portal with a carved tympanum. This portal is approached by the Pilgrim Steps, a long flight of steps 40 feet wide.
