The Adrenal Glands- structure Adrenal cortex Controlled by pituitary hormones a Adrenal Medulla Controlled by sympathetic nervous system
The Adrenal Glands - Structure
CHOH CH2OH H C=( OH Cortisol Aldosterone Testosterone Estradiol Zona glomerulosa Produces aldosterone (mineralocorticoids) Zona fasciculata Produces cortisol (glucocorticoids) Zona reticularis Produces androgens (gonadocortocoids L Adrenal cortex Derived from same embryological tissue that gave rise to gonads
Adrenal cortex Derived from same embryological tissue that gave rise to gonads (mineralocorticoids) (glucocorticoids) (gonadocortocoids)
Synthesis Cholesterol 孕烯醇酮 Pregnenolone-+ Dehydroepiandrosterone 17羟孕酮 雄烯二酮+ Progesterone -17-Hydroxyprogesterone-Androstenedione Corticosterone Cortisol Aldosterone
Synthesis 孕烯醇酮 17羟孕酮 雄烯二酮
Develops from ectoderm. the same embryological tissue that gives rise to the nervous system; 2 hormones-epinephrine and norepinephrine Stimulated directly by sympathetic division of nervous system Medulla Secretes epinephrine(adrenaline) Epinephrine and norepinephrine Adrenal medulla Capillary Preganglionic sympathetic neuron from the spinal cord CNS Adrenal medulla cells
Develops from ectoderm, the same embryological tissue that gives rise to the nervous system; 2 hormones - epinephrine and norepinephrine; Stimulated directly by sympathetic division of nervous system
