Test: Human Physiology: Endocrine System - Question 1

Which hormone does the hypothalamus produce that inhibits the release of growth hormone from the pituitary gland?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 1
Somatostatin is produced by the hypothalamus and it inhibits the release of growth hormone from the pituitary gland.
Test: Human Physiology: Endocrine System - Question 2

The pituitary hormone that stimulates the thyroid gland to produce thyroid hormones is known as:

Detailed Solution for Test: Human Physiology: Endocrine System - Question 2
Thyroid-stimulating hormone (TSH) specifically stimulates the thyroid gland to produce thyroid hormones.
Test: Human Physiology: Endocrine System - Question 3

What is the primary function of prolactin secreted by the anterior pituitary gland?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 3
Prolactin primarily regulates the growth and development of mammary glands and milk production in females.
Test: Human Physiology: Endocrine System - Question 4
Which hormone secreted by the pineal gland helps regulate sleep-wake cycles?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 4
Melatonin is secreted by the pineal gland and is crucial in regulating sleep-wake cycles and other circadian rhythms.
Test: Human Physiology: Endocrine System - Question 5
Identify the hormone responsible for increasing the blood calcium levels by promoting bone resorption.
Detailed Solution for Test: Human Physiology: Endocrine System - Question 5
Parathyroid hormone (PTH) increases blood calcium levels by promoting the resorption of bone.
Test: Human Physiology: Endocrine System - Question 6
Which gland secretes hormones involved in the 'fight or flight' response?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 6
The adrenal medulla secretes catecholamines like adrenaline and noradrenaline, which are crucial for the 'fight or flight' response.
Test: Human Physiology: Endocrine System - Question 7
Estrogens are synthesized and secreted by which of the following structures in females?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 7
Estrogens are primarily synthesized and secreted by the growing ovarian follicles in females.
Test: Human Physiology: Endocrine System - Question 8
Which hormone secreted by the pancreas lowers blood glucose levels?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 8
Insulin, secreted by the β-cells of the pancreatic islets, primarily acts to lower blood glucose levels.
Test: Human Physiology: Endocrine System - Question 9
What is the role of atrial natriuretic factor (ANF) secreted by the heart?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 9
ANF, secreted by the atrial walls of the heart, acts to decrease blood pressure by dilating blood vessels and promoting sodium and water excretion.
Test: Human Physiology: Endocrine System - Question 10
Which of the following hormones is a peptide hormone that stimulates red blood cell production?
Detailed Solution for Test: Human Physiology: Endocrine System - Question 10
Erythropoietin, primarily produced by the kidneys, stimulates the production of red blood cells.
Test: Human Physiology: Endocrine System - Question 11

Which of the following hormones is secreted by endocrine cells in the gastrointestinal tract?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 11

Gastrin is a hormone that stimulates the secretion of gastric acid and is produced by G cells in the stomach lining.

Test: Human Physiology: Endocrine System - Question 12

What is the primary function of secretin?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 12

Secretin is released in response to acidic chyme entering the small intestine and promotes the secretion of bicarbonate to neutralize stomach acid.

Test: Human Physiology: Endocrine System - Question 13

What is the primary function of the testis?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 13

The primary function of the testis is to produce androgens, which are essential for male reproductive functions.

Test: Human Physiology: Endocrine System - Question 14

Which of the following statements is true regarding hormone receptors?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 14

Hormone receptors are specific to the hormones they bind, allowing for precise regulation of physiological processes.

Test: Human Physiology: Endocrine System - Question 15

What type of hormone typically interacts with intracellular receptors?

Detailed Solution for Test: Human Physiology: Endocrine System - Question 15

Steroid hormones can pass through the cell membrane and bind to intracellular receptors, influencing gene expression.
