Where is its primordium, from which the suprarenal gland develops, located? O a. Medulla = ectoderm. O b. Cortex = mesoderm. O c.

O d. Medulla: Parallel to the development of the RENAL cortex, cells originating from the GONADAL crest invade the medial part of RENAL cortex giving rise to the medullary rays.
