Question

List the layers of the lens from internal to external, identify which layer has sutures, and which layer undergoes mitosis?

A) Layers: Lens capsule, Subcapsular epithelium, Lens fibers; The lens capsule has sutures; The subcapsular epithelium undergoes mitosis.
B) Layers: Lens fibers, Lens capsule, Subcapsular epithelium; The lens fibers have sutures; The lens capsule undergoes mitosis.
C) Layers: Subcapsular epithelium, Lens fibers, Lens capsule; The lens fibers have sutures; The subcapsular epithelium undergoes mitosis.
D) Layers: Lens capsule, Lens fibers, Subcapsular epithelium; The lens fibers have sutures; The lens capsule undergoes mitosis.

Answer 1

The layers of the lens from innermost to outermost are the Subcapsular epithelium, Lens fibers, and Lens capsule. Sutures are found in the Lens fibers, while the Subcapsular epithelium undergoes mitosis.

Step-by-step explanation:

The layers of the lens from internal to external are listed correctly in Option C, which are: Subcapsular epithelium, Lens fibers, and Lens capsule. The lens fibers have sutures that are responsible for the complex structure of the lens, often seen as a Y-shape on the anterior and posterior surfaces. The mitosis process, which is the division of cells, occurs in the subcapsular epithelium. This epithelial layer is right beneath the lens capsule and is the region where new lens fibers are continually generated throughout life to help maintain the lens's functionality and clarity.
