Endocrine system Flashcards
What is the first stage in carrying out a response using hormones
Gland receives stimulates
What is the second stage in carrying out a response using hormones
Gland releases hormone
What is the third stage in carrying out a response using hormones
Hormone travels in blood stream
What is the fourth stage in carrying out a response using hormones
Hormone received by target cell response
What is the fifth stage in carrying out a response using hormones
cell stimulated to cause desired output
What is the six stage in carrying out a response using hormones
Feedback to original gland
What gland is the origin of many early endocrine outputs
Pituarity gland
What is the thyroid gland
Regulator of metabolism
What is the adrenal gland
Controls stress response
Where is the adrenal gland located
Top of kidneys
What is the role of the pancreas
Carbohydrate metabolism
What happens when glucose levels increase
Pancreas detects the increase and secrets insulin to the blood
What does insulin do when the glucose levels increases
Makes cells more permeable to glucose
What is glucose stored in the liver called
Glycogen
When is insulin secreted
When the blood glucose is increased
When is glucagon secreted
When blood glucose is decreased
What does the pancreas do when blood glucose decreases
Secretes glucagon to stimulate release of glucose from liver
What hormone do the testes secrete
Testosterone
What hormone do the ovaries produce
Oestrogen
What does Testosterone influence
Muscle growth
What does Oestrogen influence
Hip, buttock and thigh fat
How much more testosterone do males have than females
About 10 times
Where are catecholamines produced
In the inner layer of the adrenal gland (adrenal medulla)
Where are Corticosteroids produced
Outer layer of adrenal gland (adrenal cortex)
What and when is cortisol used for
Released to break down fats and carbohydrates to provide energy during stressful situations
What purpose does aldosterone serve
Helps regulate balance of minerals, sodium and potassium in blood
Where is growth hormone released from
pituitary gland
What drives bone growth during puberty
Growth hormone
What functions does growth hormone have
Protein synthesis, fat breakdown, bone growth
Where is the thyroid gland located
Upper chest
What is the thyroid responsible for
Metabolism, use of oxygen and maintenance of temperature
