What is the endocrine system?
A network of GLANDS secreting hormones into the bloodstream.
How does the endocrine system maintain homeostasis?
By using FEEDBACK mechanisms to regulate hormone levels.
What is the most common endocrine emergency in pre-hospital settings?
DIABETIC emergencies.
Is the nervous system an actual gland of the endocrine system?
NO
T/F
The hypothalamus produce its own regulatory hormones?
TRUE
It controls pituitary gland hormone release.
What is the function of the pineal gland?
It releases MELATONIN, which influences sleep/wake cycles.
Why is the pituitary gland referred to as the ‘master gland’?
It controls hormone release by other endocrine glands in the body.
What hormone does the thyroid gland produce?
THYROXINE hormone, which regulates metabolism.
