The Endocrine System Flashcards
What does the hormone thyroxine effect
The heart rate and increases metabolic rate
How do the endocrine and ANS work in parallel
Parallel= similar/correseponds
When a stressor is perceieved the first thing that happens is the hypothalamus activates the pituitary gland which triggers activity in the sympathetic branch of the ANS
Identify and describe two glands of the endocrine system
One gland of the endocrine system is the thyroid gland. it is in charge of releasing thyroxine which affects temperature, heart rate and metabolism
Another gland is the testes which secretes testosterone.This hormone develops secondary sexual charcteristics during puberty
What is the resting state of the ANS
Parasympathetic
What is the physiologically aroused state of the ANS
Sympathetic
How does the parasympathetic nevrous system work
It works in opposition to the sympathteic
Where is the pituitary gland located and what does ut do
It is located in the brain and it is often called the master gland as it releases hormones from all over the body
What is the endocrine system
Collection of glands around the body that regulate bodily functions, growth and psychological factors
What does the hypothalamus do and what is an example of a hormone it releases
The hypothalamus links the nervous system to the endocrine system in combination with the pituitary gland
It maintains homeostasis of the body
Hormone:CRH( corticotropin releasing hormone)
What does the pancreas do and what is an example of a hormone it releases
Regulates blood sugar levels
Problems with the pancreas lead to diabetes
Hormone: insulin and glycogen
What does the adrenal gland do and what is an example of a hormone it releases
Increases heart rate, blood supply to muscles when the fight or flight mechanism is activated
Hormone: Adrenaline/cortisol
What does the Ovaries/Testosterone do and what is an example of a hormone it releases
Reproductive glands
Develops secondary sexual charcteritsics during puberty
Ovaries hormone is oestragen whilst testes is testosterone
