Where are the glands located
Just above the kidneys
Size of adrenal glands
3cm in height and 5cm in length
What are the two parts of the adrenal glands
Adrenal cortex and the adrenal medulla
Three types of steroid hormones produced by the adrenal Cortex
Mineralocorticoids, Androgens, Glucocorticoids
What are mineralocortoids produced by and what is their function?
Hormones produced by the adrenal cortex, and they help control blood pressure by balancing salt concentrations in the blood using its component Aldosterone.
What are glucocorticoids produced by and what is their function
A hormone produced by adrenal cortex, and its release is controlled by the Hypothalamus.
Contains cortisol: involved in regulating blood pressure and metabolism
Contains corticosterone: regulates immune response and suppresses inflammatory reactions
What steroid hormone, produced by the adrenal cortex, regulates metabolism, blood pressure, and immune response whilst suppressing inflammatory reactions?
Glucocorticoids
What steroid hormone produced by the adrenal cortex maintains the balance between salt and water concentrations in the body? And what hormone group is it?
Aldosterone, a Mineralocortoid produced by the adrenal cortex
Which glucocorticoid hormone helps with regulating blood pressure and metabolism
Cortisol
Which glucocorticoid hormone regulates immune response and reduce inflammatory reactions?
Corticosterone
How are mineralocortoids mediated
Signals triggered by the kidney
Androgens are created by the adrenal cortex, what is their function?
They are converted to male and female hormones
When are hormones in the Adrenal medulla released?
When the sympathetic nervous system is stimulated - due to body stress
2 kinds of peptide hormones produced by the adrenal medulla
adrenaline and noradrenaline
Where are adrénaline and noradrenaline produced?
In the adrenal medulla
What is the effect of adrenaline on liver cells?
Rapidly increases blood glucose concentration by facilitating the conversion of glycogen to glucose
Another term for liver cells
Hepatocytes
hepatocytes
Liver cells
What does adrenaline do, and where is it produced?
Increases heart rate, dilates pupils, gets body ready for fight or flight, and is produced in the adrenal medulla
What is the function of noradrenaline
Works with adrenaline to produce fight or flight reactions, and is produced in the adrenal medulla
What group of hormones does the adrenal cortex produce
Steroids
What group of hormones does the adrenal medulla produce?
Peptide hormones
