The adrenal medulla develops from the neuroectoderm.
Norepinephrine regulates the blood pressure under normal condition.
Norepinephrine is called as emergency hormone as it is secreted during the time of emergency
The adrenal medulla consists of granular cells that are modified postganglionic cells of the sympathetic nervous system
Epinephrine or Adrenaline:
It is secreted at the time of emergency. Hence it is also called emergency hormone.
It has a greater effect on cardiac activity than norepinephrine.
It causes only weak constriction of the blood vessels of the muscles in comparison with a much stronger constriction that results from norepinephrine.
Both adrenaline and noradrenaline act on the cells of skeletal, cardiac and smooth muscles and blood vessels and fat cells.
Because of the role of their hormones, the adrenal glands are also called ‘glands of emergency’.
