The central region formed by older fibers is called what?

Explanation:
In the lens, growth occurs by adding new elongated fiber cells at the outer regions while the oldest fibers stay in the center. The central mass formed by these older fibers is called the nucleus. The surrounding, newer fibers make up the cortex, and the entire lens is enclosed by a capsule with an anterior surface lined by a single layer of epithelial cells. So the central region formed by older fibers is the nucleus.
