Simple cuboidal epithelium
Explanation:
The epithelium are tissues that line body surfaces and internal organs.
They can be Squamous-,cuboidal or Columnar.
The function of epithelium is to protect the underlying tissue from physical and chemical trauma.
They also help in absorption example in the digestive tract
They help in secretion of hormones in to the vascular system.
In the proximal Tubule of the nephron, it is lined up with the Simple cuboidal epithelium consisting of cells that are cube-like.

The X-shaped structure is the optic chiasma (part of the optic nerve).
Structure of the optical chiasma:
The fibers from the ganglion cells of the nasal retina and the temporal retina come together and leave the eyeball to form the two optic nerves (forming an X-shape). Each optic nerve passes through the optic hole of the sphenoid bone and extends in and out of the skull. The two nerves meet at the front and above the pituitary to form the optic chiasma. At this level, fibers from the nasal retina intersect while those from the temporal retina continue in the same trajectory to form the two optical tracts.
