Sample Questions from the Nutrition and Chronic Disease- Test 2 Flashcards

Question: Normal Anatomy and Physiology of the Endocrine System • Endocrine Function – Thyroid Gland

Choices:

• Located in neck • Controls metabolic rate • 2 iodine-containing hormones – Thyroxine – T4, less active form, produced in thyroid gland – Triiodothyronine – T3- more active (T4->?T3 is an enzymatic reaction taken place in anterior pituitary, liver and kidney; deiodinase is a selenium-containing enzyme).

Question: Other Endocrine Disorders • Pituitary Disorders – Pituitary Tumors

Choices:

– Cushing’s Syndrome: hypercortisolism. Increased endogenous production from adrenal glands or use of synthetic steroids.

Question: Disorder • Hypothyroidism – Definition

Choices:

• Decreased production and secretion of thyroid hormones and most common pathologic hormone deficiency • Cretinism – congenital; dwarfism and metal retardation in children • Adult: goiter Iodine deficiency

Question: Normal Anatomy and Physiology of the Endocrine System • Endocrine Function – Pituitary Gland

Choices:

• Base of the brain • Anterior and posterior pituitary – Six hormones from anterior pituitary control the secretion of other hormones – Vasopressin and oxytocin: synthesized from hypothalamus. Stored at and secreted from posterior pituitary – Hormones are NOT secreted all the time

Question: Normal Anatomy and Physiology of the Endocrine System • Classification of Hormones – Format

Choices:

• Protein/peptides (major form) • Amines (rare, derivatives of tyrosine) • Steroids (sex hormones, derived from cholesterol)

Question: Disorder • Hypothyroidism – Pathophysiology

Choices:

• Reduced production of T4/increased TSH • Hyperplasia and hypertrophy of gland (stimulated by TSH)

Question: Normal Anatomy and Physiology of the Endocrine System • Classification of Hormones – Functions of major hormones

Choices:

• Reproduction and sexual differentiation (from sex organs) • Growth and development (e.g. from pituitary) • Energy homeostasis (e.g. pancreas) • Regulation of metabolism (e.g. thyroid hormone)

Question: Disorder • Hypothyroidism – Clinical manifestations

Choices:

• Subtle or no symptoms • Reduction in metabolic activity

Question: Other Endocrine Disorders – Epidemiology and Etiology

Choices:

• Relatively rare in children • Graves’ disease- most common cause

Question: Other Endocrine Disorders • Hyperthyroidism – Definition

Choices:

• Excessive secretion of thyroid hormones

Question: Parts of Thyroid gland

Choices:

Right lobe, Trachea, Isthmus, and Left Lobe.
