EXTRACELLULAR MATRIX. The extracellular matrix of connective tissue is composed of ground substance and fibers. In ordinary connective tissue, the ground substanc e consists mainly of water. The principal fiber type is collagen (the most abundant protein in the body), with elastic fibers as a minor element.The extracellular materials which comprise the matrix are produced by fibroblasts.n ordinary connective tissue, the ground substanc e consists mainly of water.

Major airlines require more flight hours and experience from pilots than that demanded by commuter and regional airlines. As of 2012, the salary range for regional airline pilots was $16,500 to $60,000, according to AvScholars, an organization that guides would-be aviators in education and career.
If you were to poll a group of random airline pilots about their salaries, youâd get a surprisingly vast range of numbers. One pilot makes only $24,000 per year while another makes over $200,000 per year. But interestingly, while airline pilot salaries vary wildly, they are pretty straightforward. So why the huge variation in pay between airline to airline or pilot to pilot when all pilots have to meet the same stringent requirements?
