This "Master Gland" is located at the base of the brain
Pituitary Gland
The pancrease releases this hormone to lower high blood sugar levels
insulin
This type of feedback loop orks to oppose a stiulus and maintain stability.
Negative Feedback
unlike the nervous system which uses electricity the endocrine system uses these chemical messengers
Hormone
This condition occurs when the pancreas fails to produce enough insulin or the body ignores it
diabetes
This butterfly - shapes gland is found in the neck wrapped around the trachea
Thyroid Gland
This hormone is responsible for the fight or flight response during emergency's
Epinephrine
in this rare type of loop the body moves away from equilibrium to complete a specific process such as childbirth
positive feedback
hormones travel through this system to reach distant parts of the body
circulatory
an overactive thyroid gland ( hyperthyroidism) can lead to this, a swelling in the neck
goiter
These glands sit like small hats on top pf each kidney
Adrenal Glands
This hormone signals the liver to release stored glucose when blood sugar is low.
Glucagon
during labor this hormone causes contractions which lead to more hormone release a classic positive feedback loop
oxytocin
Fill in the blank : A hormone can only affect a specific cell if that cell has the correct _____ to catch it
receptors
too much growth hormone during childhood can lead to this condition
gigantism
This brain structure acts as the bridge between the nervous and endocrine system
Hypothalamus
Produced by the pineal gland this hormone regulates sleep-wake cycles
Melatonin
this term describes the stable balanced internal environment that feedback loops work to maintain
homeostasis
these are the specific cells that a hormone is intended to influence
targeted cells
if the adrenal glands produce to much cortisol over a long period it can result in this " c- named" syndrome
Cushing's syndrome
These are the four tiny glands located on the posterior surface of the thyroid
Parathyroid Glands
The thyroid hormone requires iodine and is the main regulator of metabolism
Thyroxine or (T4)
if a gland continues to overproduce a hormone despite a " stop" signal it is considered a failure of this specific mechanism
Negative Feedback loop
this is the term for glands that secrete hormones directly into the blood rather than though a duct
endocrine
this hormone is often called the stress hormone and can suppress the immune system if levels stay high to long
cortisol
