Another histological difference between cardiac muscle and skeletal muscle is that the T-tubules in the cardiac muscle are bigger and wider and track laterally to the Z-discs. There are fewer T-tubules in comparison with skeletal muscle.nother histological difference between cardiac muscle and skeletal muscle is that the T-tubules in the cardiac muscle are bigger and wider and track laterally to the Z-discs.

President Jefferson put the interests of the nation above ideological considerations when confronted with the purchase of the Louisiana Territory. When Robert Livingston and James Monroe returned from Paris with the 1803 Louisiana Territory Purchase Treaty, President Thomas Jefferson was faced with a dilemma. Jefferson had sent Monroe to Paris to negotiate the purchase of New Orleans for $2 million.
President Thomas Jefferson commissioned the Corps of Discovery Expedition (1804-06), led by Meriwether Lewis and William Clark, to explore the territory acquired in the Louisiana Purchase, among other objectives. In 1801, Spain signed a secret treaty with France to return Louisiana Territory to France.
