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.
The main body of the cathedral was completed in only 38 years, from 1220 to 1258. The cathedral has the tallest church spire in the United Kingdom (123m/404 ft). Visitors can take the Tower Tour where the interior of the hollow spire, with its ancient wood scaffolding, can be viewed. The cathedral also has the largest cloister and the largest cathedral close in Britain (80 acres (32 ha)).
