Biopsychology: The Endocrine system Flashcards
The endocrine system
A network of glands. Glands release hormones into the bloodstream.
The role of glands are to…..
To secrete hormones which will have an impact to a target organ
Hormones
Chemicals produced by your glands that regulate the activity of cells/organs in the body
How are hormones transferred?
Through the bloodstream`
How does the endocrine system compare to the nervous system?
Works at a slower rate which has widespread and powerful effects
What does the endocrine system maintain
A level of homeostasis
What glands are controlled by the hypothalamus?
Endocrine glands
What does the pituitary gland do?
Produces and secretes hormones that influence the release of hormones from other glands
What does the anterior pituitary gland release in response to stress, and what gland does this hormone stimulate?
releases ACTH in response to stress
ACTH stimulates the adrenal glands to produce cortisol
Where is the pituitary gland located?
Hypothalamus
What 3 hormones does the anterior pituitary gland produce?
ACTH
LH - Luteinising hormone
FSH - Follicle stimulating hormone
LH and FSH are secreted by the anterior pituitary gland, which stimulate what? (males and females)
Females: stimulate ovaries to produce oestrogen and progesterone
Males: stimulates testes to produce testosterone and sperm
What does the posterior pituitary release, and what does this stimulate?
Oxytocin
Stimulates contraction of uterus during childbirth
Where are the adrenal glands located?
on top of each kidney
What is each adrenal gland made up of?
