Study Notes
Adrenal Glands Structure and Development
- The main part of the adrenal glands is the adrenal cortex.
- The adrenal cortex is derived from the mesoderm, a embryonic origin.
- The adrenal glands are approximately 5 cm in length, 3 cm in width, and 1 cm in thickness in humans.
- The adrenal medulla accounts for about 10-20% of the adrenal glands.
- The cells of the adrenal medulla are derived from the neural crest, a specific embryonic origin.
