    zona glomerulosa is at periphery-but I think the most outside layer is the capsule

    Zona Glomerulosa

    The concentration of sodium in the blood is affected by a hormone secreted by cells in which zone in the photomicrograph? Name it:
    The Hormone they refer is the mineralocorticoid ALDOSTERONE which is produced in the Zona Glomerulosa of the Adrenal Cortex.

    Remember: ADRENAL GLAND histology:
    1) CAPSULE: nothing

    2) CORTEX: (originate from MESODERM)
    - Zona Glomerulosa: Mineralocorticoids
    - Zona Fasciculata: Cortisol:Glucocorticoids
    - Zona Reticularis: Gonadocorticoids

    3) MEDULLA: (originate from ECTODERM)
    - Adrenal Medulla: Chromafin cells --> Epinephrin and NE
