These are
two endocrine glands one at the above of each kidney. This endocrine gland has
two parts i.e. outer part is “Adrenal Cortex” and inner parts is ”Adrenal
Medula”.
Adrenal
cortex secrets “Corticoids hormones “. These hormones regulates the level of sugar and mineral metabolism in body.
Adrenal Medula secretes “Epinephrine”
and “Nor-epinephrine”.
Epinephrine
or Adrenaline is called as “Emergency hormone” as it prepares body for sudden circumstances.Strong emotions such as fear or anger cause epinephrine secretion in blood stream. It increase heart beat rate, muscle strength,
blood pressure, and sugar metabolism.
Nor-epinephrine acts when body is in rest it increases heart rate and blood
pressure, triggers the release of glucose
from energy stores, increases blood flow to skeletal muscle, reduces blood flow
to the gastrointestinal system, and inhibits voiding of the bladder and
gastrointestinal motility.
