Endocrine System Hormones and Metabolic Syndrome Flashcards
What does hypothalamus regulate, what is it responsible for?
Regulates the Pituitary Gland
Responsible for regulation of the Autonomic Nervous System (ANS) (body temperature, appetite, sweating, thirst, sexual behavior, fear, BP, sleep)
What hormones are released from the Anterior Pituitary?
6 Hormones:
- Adrenocorticotropic Hormone (ACTH)
- Thyroid Stimulating Hormone (TSH)
- Follicle Stimulating and Luteinizing Hormone (FSH & LH)
- Growth Hormone (GH)
- Prolactin
What hormones are released from the Posterior Pituitary?
2 Hormones:
- ADH/Vasopressin
- Oxytocin
What does ACTH stimulate?
Adrenal Cortex
What does TSH stimulate?
Thyroid Gland
What does FSH and LH stimulate?
Ovaries and Testes
What does GH stimulate?
Bones and Tissues
What does Prolactin Stimulate?
Milk Production in Breasts
What is the function ADH/Vasopressin?
Regulates water and mineral balance; water retention
What is the function of Oxytocin?
- Stimulate uterine contractions during birth
- Ejection of Milk
Production of Milk (Prolactin)
What does the Adrenal Cortex Secrete?
Cortisol
Aldosterone
What does the Thyroid Gland Secrete?
Triiodothyronine (T3)
Thyroxine (T4)
What do the Ovaries and Testes secrete?
Estrogen, Progesterone and Testosterone (testes)
What is the function of GH?
Growth and Metabolism
Function of the Thyroid Gland?
Production of Hormones that control metabolism of cells
Function of the Parathyroid Gland?
Regulation of Calcium and Phosphate Metabolism
Function of the Adrenal Gland?
Aldosterone:
- Regulation of Water and Sodium balance
Cortisol:
- Stress response
What is Metabolic Syndrome?
Consists of Signs and Symptoms that are risk factors for type 2 diabetes, cardiovascular disease and stroke.
What makes a diagnosis of metabolic syndrome? General Categories?
Having 3 or more risk factors for metabolic syndrome.
General Categories:
- Waist Circumference
- Triglycerides Level
- HDLs
- BP
- Fasting Blood Glucose
Value for Metabolic Syndrome: Waist Circumference
Waist Circumference > 40 in Men (> 102 cm)
Waist Circumference > 35 in Women (>88 cm)
Value for Metabolic Syndrome: Triglycerides
150 mg/dL or higher
Value for Metabolic Syndrome: HDLs
< 40 mg/dL in Men
< 50 mg/dL in Women
Value for Metabolic Syndrome: Blood Pressure
SBP = 130 mmHg and/or DBP = 85 mmHg
Value for Metabolic Syndrome: Fasting BG
Fasting BG > 100 mg/dL
(< 100 is normal, > 100 - 125 is already the prediabetes range)
