Mr 10 Divergence Betwixt Adrenal Cortex In Addition To Adrenal Medulla

Adrenal glands are paired structures located on the overstep of the kidneys.  Each adrenal gland has 2 parts: external adrenal cortex together with internal adrenal medulla. Adrenal cortex shows 3 concentric zones: zone glomerulosa, zona fasciculata, together with zona reticularis. Adrenal medulla consists of rounded groups of relatively large together with granular cells called chromaffin cells.

Adrenal  Cortex vs Adrenal  Medulla

Adrenal  Cortex
1. It is outer describe of piece of job solid part of the adrenal gland
2. It forms nigh 75% part of the gland.
3. It is enclosed past times a fibrous capsule.
4. It develops from the mesoderm.
5. It comprises 3 regions or zones a) Outer sparse zona glomerulosa b)middle thick zona fasciculata together with c) inner sparse zona reticularis.
6. It is essential for life. Its devastation causes death.
7. It is stimulated to loose its hormones past times ACTH (Addrenocorticotrophic hormone) from the anterior lobe of pituitary gland.
8. It secretes 3 groups of hormones: mineralocorticoids, glucocorticoids together with gonadocorticoids.
9. There is no cooperation betwixt adrenal cortex together with sympathetic nervous system.

Adrenal  Medulla
1. It is primal soft part of the adrenal gland
2. It forms nigh 25% part of the gland.
3. It is non enclosed past times a fibrous capsule.
4. It develops from ectoderm.
5. It is non differentiated into regions. It consists of chromaffin cells. The adrenal medulla is exactly an extension of the sympathetic nervous system.
6. It is non together with then essential for life. Its devastation does non sweat death.
7. It is stimulated to secrete its hormone past times nervus impulses reaching through sympathetic nervus fibres.
8. It secretes 2 like hormones: adrenaline together with nonadrenaline.
9. Adrenal medulla together with sympathetic nervous organisation part equally an integral ststem called sympatheticoadrenal system.
