Other important bones in the shoulder include: 1  The acromion is a bony projection off the scapula. 2  The clavicle (collarbone) meets the acromion in the acromioclavicular joint.
List of boroughs and census areas in Alaska. The U.S. state of Alaska is not in counties, as 48 other states are (Louisiana has parishes instead). It is in boroughs. Many of the more densely populated parts of the state are in Alaska's eighteen organized boroughs, which are somewhat similar to counties in other states.
The Alaska State Legislature includes a Senate and House of Representatives. Forty representatives are elected to two-year terms; twenty senators serve four-year terms. Two basic forms of local government exist in Alaska: the city and the borough. The borough is similar to the county in many other states. Alaska is unique because most of it has not been organized into political units. Currently, thirteen organized boroughs cover about one-third of the state.
