HERLIHY ENDOCRINE SYSTEM STUDY GUIDE
2026 COMPLETE TEST QUESTIONS AND
ANSWERS
◉ Negative feedback
Biorhythms
CNS. Answer: Mechanisms to control secretion of hormones
◉ Negative feedback control. Answer: As the gland secretes its
hormone to the target tissue, the target tissue will produce a
chemical, as the chemical concentration in the blood rises, the gland
will notice that rise and reduce its secretion of the hormone and
then the process will start over again
◉ Positive feedback control. Answer: the change produced by the
hormone causes more hormone to be released, often designed for a
rapid response
◉ Biorhythms. Answer: rhythmic alteration in a hormone's rate of
secretion, can be disturbed by travel, alterations in sleeps patterns
◉ circadian rhythm. Answer: A pattern that repeats every 24-hours,
ex cortisol secretion and female reproductive hormones
, ◉ Chronopharmacology. Answer: study of the effects of biorhythms
on drug effects
◉ Control by CNS. Answer: Activation of hypothalamus and
stimulation of the sympathetic nervous system
◉ Pituitary gland. Answer: Pea-sized gland inferior to the
hypothalamus, two main parts (anterior/posterior)
◉ Hypothalamus. Answer: Secretion of anterior pituitary gland is
controlled by:
◉ releasing and release-inhibiting hormones. Answer: how the
hypothalamus regulates secretion of anterior pituitary hormones
◉ Hypothalamic-hypophyseal portal system. Answer: Network of
capillaries that connects hypothalamus to anterior pituitary
◉ Hormones of the anterior pituitary. Answer: - Prolactin
- Adrenocorticotropic hormone (ACTH)
- Gonadotropins (FSH, LH)
- Thyroid-stimulating hormone (TSH)
