HSS 3305 MODULE 10 PRACTICE EXAM
QUESTIONS WITH VERIFIED ANSWERS
What is pituitary apoplexy?
Sudden-onset bleeding or infarction of the pituitary gland or tumor, manifesting as severe
headache and may include diplopia, vision loss, or hypopituitarism.
What are the symptoms of pituitary apoplexy?
Symptoms include sudden headache, vision loss, ptosis, nonreactive pupil, and paralysis of eye
movement.
What is the primary treatment for pituitary apoplexy?
Emergency endoscopic endonasal resection of the macroadenoma and administration of
intravenous hydrocortisone.
What is the role of the hypothalamus in the endocrine system?
The hypothalamus controls the secretion of anterior lobe hormones and links the nervous and
endocrine systems.
What are the major endocrine organs?
Pancreas, adrenal gland, thyroid gland, pineal gland, and gonads (ovaries and testes).
How are hormones classified chemically?
Hormones are classified into steroid hormones and nonsteroidal hormones (amine, peptide, and
protein hormones).
What are steroid hormones derived from?
Steroid hormones are lipids derived from cholesterol.
What is an example of an amine hormone?
Epinephrine or norepinephrine.
What are peptide hormones made of?
Peptide hormones are made of a few amino acids.
What is the function of oxytocin?
Oxytocin stimulates contractions during birth and plays a role in social bonding.
What triggers hormone secretion?
Hormone secretion can be triggered by humoral, neural, or hormonal stimuli.
, What is humoral stimulus in hormone secretion?
Hormone release caused by changing ion or nutrient levels in the blood.
What is neural stimulus in hormone secretion?
Hormone release caused by neural input.
What is hormonal stimulus in hormone secretion?
Hormone release caused by another hormone (a tropic hormone).
What is the function of insulin?
Insulin regulates blood sugar levels by facilitating glucose uptake in cells.
What hormone does the adrenal medulla secrete?
Epinephrine, which is involved in the fight or flight response.
What hormones are secreted by the anterior pituitary gland?
FSH, LH, Prolactin, Growth hormone (GH), ACTH, and TSH.
What is the function of thyroxin?
Thyroxin regulates metabolic rate.
What are the functions of cortisol?
Cortisol helps manage stress and regulates metabolism.
What hormones do the ovaries produce?
Estrogen and progesterone.
What is the role of the pineal gland?
The pineal gland secretes melatonin, which regulates the biological clock.
What is the function of the thyroid gland?
The thyroid gland regulates metabolic rate through the secretion of thyroxin.
What is the function of testosterone?
Testosterone is responsible for male characteristics and reproductive functions.
What is the significance of visual deficits in pituitary apoplexy?
Visual deficits indicate the need for surgical decompression.
What is the outcome of treatment for pituitary apoplexy?
With treatment, visual acuity can return to baseline, and symptoms may resolve.
