Endocrine System Flashcards
What are the 4 purposes of the Endocrine System?
Body growth, metabolism, sexual development and homeostasis.
What is Homeostasis?
It is a process wherein body biological processes adjusted to adapt to conditions using hormones.
This gland is known as the “Master” gland. It controls the Hormone system of the body and stimulates hormone creation through the Pituitary gland.
Hypothalamus
What hormones does the Hypothalamus and Pituitary Gland produce and what are their purposes?
Growth-Releasing Hormone (GHRH) - Stimulate production of Growth Hormone (GH) by Pituitary Gland to begin body growth.
Gonadtropin-Releasing Hormone (GnRH) - Stimulate production of Lutenizing (LH) and Follicle-Stimulating Hormone (FSH) on the onset of puberty and sexual development.
Thyroxin Releasing Hormone (TRH) - Maintain Thyroid hormone.
Antidiuretic Hormone (ADH) - Reduce production of urine by the kidney to prevent dehydration.
This gland is located in the lower endocrine system and is responsible for our body’s fight or flight response hormone, a.k.a adrenaline.
Adrenal Gland
Hypothyroidism and Hyperthyroidism are conditions of what gland?
Thyroid Gland
This gland produces Thymosin to create antibodies in our immune system.
Thymus Gland
The Pineal gland and it’s hormone is responsible for?
Circadian rhythm and the timing of our sleep.
What are the 4 functions of the Thyroid gland?
Metabolism, brain growth, maintenance of bone health, and regulation of body vital organs.
What hormone does the Thyroid gland produce?
Thyroxin
What is Addison’s Disease and what are it’s symptoms?
Lack of Cortisol/Aldosterone produced from the Adrenal Gland’s Cortex.
Symptoms: Fatigue, low mood, weak muscle and weight loss.
What gland produces insulin to reduce blood glucose levels?
Pancreas
What are some symptoms of Hyperthyroidism?
Heat intolerance, short and light periods, nail thickening and flaking, increased heart rate, and a larger thyroid gland or goiter.
What do Hypothyroidism and Hyperthyroidism patients experience in common?
Fatigue, insomnia and hair loss
What type of feedback mechanism is exhibited during childbirth, when oxytocin hormones are released at a higher rate, resulting in stronger contractions?
Positive feedback
What is Cushing’s Disease and what are it’s symptoms?
Too much cortisol produced, resulting in sudden weight gain, high or low blood sugar and muscle loss.
