Not a category of water-soluble hormones:
Steroid
Protein
Peptides
What does the endocrine system do?
Senses the hormone levels in the blood
Controls all other endocrine glands
The primary role of the parathyroid gland is:
To maintain metabolic homeostasis
To regulate serum calcium levels
The release of insulin from the pancreas is triggered by a rise in blood glucose levels. This hormone-production pathway is triggered by:
Hormonal stimuli
Humoral stimuli
Neural stimuli
Negative stimuli
The hormone concentration in the blood is influenced by:
Production of receptor antagonist
Indirect growth-promoting effects
Nutritional signals to the endocrine gland
Positive and negative feedback loops
What types of cells can be found in the parathyroid gland?
Alpha and beta cells
Chiefcells and oxyphil
Parafollicular and follicle cells
Pituicytes and basophil cells
Which type of epithelium is found in thyroid follicles?
Squamous
Cuboidal
Transitional
Columnar
Which of the following hormones is not produced by the anterior pituitary?
Oxytocin
Growth hormone
Prolactin
Thyroid-stimulating hormone
During development phase of endocrine system, the pituitary gland, adrenal medulla, and pineal gland are developed from
Ectoderm
Endoderm
Mesoderm
The class of adrenal gland hormones that provides resistance to stress, produces anti-inflammatory effects, and promotes normal metabolism to ensure adequate quantities of ATP is
Catecholamine
Androgens
Glucocorticoids
Mineralocorticoids
The condition of Cushing’s syndrome is characterized by breakdown of muscle proteins and redistribution of body fat. What may produce this condition?
Hyposecretion of cortisol by the adrenal cortex
Hypersecretion of cortisol by the adrenal cortex
Hyposecretion of glucocorticoids and aldosterone
Hypersecretion of human growth hormone during childhood
Melatonin is secreted by
Pineal gland
Skin
Pituitary gland
Thyroid
Pinealocytes cells occurs in
Pituitary body
Pineal gland
Adrenal gland

Retention of sodium in body depends up on hormone from
Adrenal cortex
Adrenal medulla
Parathyroid
Thyroid
Which of the following does the adrenal cortex produce?
Noradrenaline
Aldosterone
Cortisol
Adrenal
Which of the following are Sertoli cells responsible for producing?
Testosterone
Estrogen
Gonadotropin releasing hormone (GnRH)
Androgen binding globulin (ABG)
Growth factors are local hormones that stimulate cell growth and division
TRUE
FALSE
If the effect of 2 or more hormones acting together is greater than the sum of each acting alone, then the 2 hormones are said to have a permissive effect.
TRUE
FALSE
In the direct gene activation method of hormone action, the hormone enters the target cell and binds to an intracellular receptor. The activated receptor- hormone complex then alters gene expression to produce the protein that cause the physiological responses that are characteristic of the hormone.
TRUE
FALSE
Productive stress is term as distress
TRUE
FALSE
