Structure I
Hormones are released directly into this
What is the blood stream?
This gland produces oxytocin
The human body contains this many major endocrine glands
Hormones act more ________ in comparison to nerve impulses
Slowly
A high blood glucose level triggers the pancreas to stop making this hormone
What is the hypothalamus?
The anterior lobe of the pituitary gland secretes this hormone, which largely determines an individual's height and size
What is growth hormone?
This hormone, secreted by the posterior lobe of the pituitary gland, stimulates smooth muscles to contract
What is oxytocin?
These two body organs help break down and eliminate hormones from the body
What are the liver and kidneys?
A low blood glucose level signals the pancreas to stop producing this hormone
What is insulin?
This hormone is secreted by the pineal gland in response to darkness
What is melatonin?
This endocrine gland produces epinephrine and norepinephrine
What is the adrenal gland?
What is the hypothalamus?
This type of hormone has a high lipid content and can easily diffuse through the target cell's cell membrane and enter the cytoplasm
What is a steroid hormone?
Non-steroidal hormones act through the use of these in the cytoplasm of the cell
What are second messengers?
This gland sits in front of the trachea
What is the thyroid gland?
This hormone, secreted by the adrenal gland, regulates the concentration of minerals, ions, and water in the blood and urine
What is aldosterone?
Insulin and glucagon are produced by these cells in the pancreas
What are the islets of Langerhans?
Feelings of depression or mood swings can be partially caused by this in the body
What are hormones?
This is one of the ways endocrine glands are controlled. The other way is by negative feedback mechanisms.
What are other endocrine glands?

What is calcitonin?
This hormone, secreted by the adrenal gland, helps regulate glucose metabolism during emergencies
What is cortisol?
This hormone, secreted by the anterior lobe of the pituitary gland, controls the production of thyroxine and triiodothyronine
What is TSH?
Puberty is brought on by hormones produced by the gonads when stimulated to do so by other hormones called _________ from the pituitary gland
What are gonadotropins?
This hormone, released by the thyroid, increases oxygen use, stimulates heat production in most tissues and indirectly affects growth.
What is thyroxine?
