Glands
This gland regulates metabolism
Thyroid
This hormone lowers blood sugar
Insulin
Caused by too little or NO insulin
Diabetes mellitus
The endocrine system mainly controls this type of body response (fast or slow)
Slow response
Most hormone regulation works through this type of feedback
Negative Feedback
Secretes melatonin
Pineal Gland
This hormone is released during stress and raises the heart rate
Adrenaline/Epinephrine
This disorder involves too much thyroid hormone
Grave's disease (hyperthyroidism)
Hormones travel through this to reach target cells
Bloodstream
In negative feedback, the response does this to the original stimulus
Reduces
Referred to as the "Master Gland"
Pituitary Gland
This hormone stimulates the growth of bones and muscles
Growth Hormone (GH)
This disease is caused by too much GH in children
Gigantism
This system works closely with the endocrine system to maintain homeostasis.
Nervous system
This is an example of positive feedback in the body.
Oxytocin during childbirth
Glands that are triggered as flight or fight response
Adrenal Glands
This hormone increases blood calcium levels
Parathyroid hormone (PTH)
This disorder results from too much cortisol
Cushing's disease
Hormones bind to these on target cells.
In a thyroid feedback loop, high T3/T4 levels cause this hormone to decrease.
TSH
Secretes the hormone Prolactin
Pituitary gland
This hormone controls metabolism and is produced by the thyroid
Thyroxine
This disorder results from too little cortisol
Addison's disease
This is the body’s ability to maintain internal balance.
Homeostasis
When blood glucose levels rise, insulin is released. As glucose levels return to normal, insulin secretion decreases. This is an example of what type of feedback?
Negative Feedback
