The endocrine system

Question 1

Effects of the re-movement of testosterones

Answer 1

Testosterones - removed means that the voice doesn’t break

Question 2

Insulin- discovered in 1922 (100) years ago
who discovered insulin Fedrick …

Answer 2

insulin allows sugar to enter the cells
with diabetes the lack of insulin means that sugar floats around the blood not feeding the cells

Question 3

What body systems are responsible for the receiving of sensory information and coordinating body responses

Answer 3

Nervous system & Endocrine system

Question 4

What produces hormones

Answer 4

All of our organs

Question 5

what does endocrine system consist of

Answer 5

ductless glands that are largely seperated from each other anatomically but they share the same function to secrete glands

Question 6

Endocrine tissues

Answer 7

Hypothalamus
Brain
Adipose tissue
Kidneys
Liver
Stomach
small intestine
Heart
skin
Placenta

Question 8

Endocrine hormones function

Answer 8

Chemical composition and volume of internakl environment
Regulating nutrient metabolism and water and electrolyte balance
contraction of smooth cardiac muscles fibres

Question 9

Homeostatic control

Answer 9

Stimulus- first point - produces a change to the variable
then we need it to travel to the control center

Receptor - detects the change. The receptor monitors the environment and respond’s to change (stimuli)

Input- Information travels along the pathway to the control centre. The control centre determins the appropiate response deciding what action to take next

output
response

Question 22

hypothalamus and pituitary gland

Question 23

Hypothalamic-hypophyseal tract

Question 24

Endocrine glands - anterior pituitary gland

Question 25

Endocrine glands- Adrenal glands

Question 26

Age and endocrine system

Question 27

what is the role of GHRH

Answer 27

stimulates the release of a growth hormone from the arterior piturity gland
.growth hormone - stimulates the break down of fats for enegy and conversion of glycogen to glucose
(at pubity the sex steriods eg testoroston estrogen pegestrone start the process of closing down the growoing parts the lomg bones epithiceal lates- where the bones grow and extemnd they are ssnitibve tio sex cells
Anabolic - meeans that something is changing in the way it is being vbult up
catabolic- breaking things down
together they make up metabolic (metabolism

anabolic - vastly increased release of anabolic sex steroids stayt the process of closing downthe growing p[arts of the bone
the apethiceal plates slow process the growth of bones increases fior a while
growth hormones can elevate blood glucose
growtgh hormones are also anabolic (helps increase muscle mass, makes them look leaner)

metabolic
the fgrwoing parts
.adrenal glands

.adrenal cortex
produces 2 types of steroid hormones - cortisol, aldeserone
aldesterone- involved in sodium metabloism
cortisol- involved in stress control and elavating glucose
only hormone effective in bringing diwn glucose is insluin its the only hypoglycemic hormone
there are serveral hormones which can elevate it
glucagon

adrenal medulla

Question 28

Thyroid

Answer 28

Your thyroid hormone fluctuates acording to the weather when its cold you wikll produce more, it helops to jkeep you warm
thyroid olevekls reduce and metabolism slows down seasonal fluctuation
