ADRENAL CORTEX AND ADRENAL MEDULLA HORMONES Slide2
Adrenal
glands are two pyramid-shaped structures that sit on top of the kidneys, one gland each kidney.Slide3
Adrenal
glands release hormones that help the body prepare for and deal with stress. Slide4
An adrenal
gland has an outer part called the adrenal cortex and inner part called the adrenal medulla
.Slide5Slide6
ADRENAL CORTEX About 80 % percent of adrenal cortex produces more than two dozen steroid hormones called corticosteroids.ALDOSTERONE
CORTISOL Slide7Slide8
AldosteronAldosteron regulates the reabsorption of sodium ions and excretion of potassium ions by kidneys.Slide9
Cortisol
Helps control rate of metabolism of carbonhydrates, fats and proteins.Helps people cope with stress.Slide10Slide11

ADRENAL MEDULLA
Adrenal medulla is a specialized part of the sympathetic nervous system. For this reason, the adrenaline and
noradrenaline
it
secretes
are
called
neurohormones
.
Adrenaline is
sometimes
known
epinephrine
.
The
words
adrenaline
and
epinephrine
are
derived
from
Latin
and
Greek
words
,
and
mean
“
near
the
kidneys
”.Slide17
Adrenal
medulla produces the “fight or flight” response to stress. This response is the feeling, you
are
excited
or
frightened
.Slide18
ADRENAL MEDULLA HORMONES
AdrenalineNoradrenalineSlide19
Adrenaline
causes the heart rate to increase, respiration rate to increase, smooth muscle in air ways to relax,muscles in the arteries to contract and glucose levels to increase.Slide20
Noradrenaline
Noradrenaline or norepinephrine is a neurotransmitter released by the nerve cells. Its chemical structure as well as function is similar to adrenaline. It increases blood pressure by constricting the blood vessels. This action normalizes heartbeat due to which breathing becomes more deep and normal. The main purpose of Noradrenaline is to normalize life threatening low blood pressure
(acute hypotension).Slide21
Noradrenaline
deficiency can lead to tiredness, fatique, lethargy and sullenness.Slide22
