Q1: The pituitary gland has _________ lobes which secrete ___________ hormones.
A: The pituitary gland has two individual lobes, which secrete different hormones
Q2: Considered the master gland, the ____________ gland receives its primary direction from the
__________.
A: Considered the master gland, the pituitary gland receives its primary direction from the hypothalamus.
Q3: Hormone regulating medications work with the __________ gland to maintain homeostasis.
A: Hormone regulating medications work with the pituitary gland to maintain homeostasis. The mechanism of action
varies depending on the hormonal regulation drug, either augmenting or antagonizing the effects of pituitary
hormones to maintain homeostasis within the body.
Q4: Hormonal Regulation Drugs
A: Overview -The pituitary gland receives direction from the hypothalamus, forming the neuroendocrine system, which
maintains hormonal stability in response to stimuli both internal and external. Pituitary Gland Function -The pituitary
gland secretes hormones that have highly specialized functions related to their target cells or organs. -The gland has
two distinct lobes, each secreting its own set of hormones. Anterior Pituitary Hormones -Adrenocorticotropic
Hormone (ACTH) Targets the adrenal cortex. → -Growth Hormone (GH) Targets bone/muscle. →
-Thyroid-Stimulating Hormone (TSH) Targets the thyroid. → -Prolactin Targets the breast. → -Follicle-Stimulating
Hormone (FSH) Targets the ovary. → Posterior Pituitary Hormones -Antidiuretic Hormone (ADH) Targets the
kidneys. → -Oxytocin Targets the breast. →
Q5: As one-half of the neuroendocrine system, the hypothalamus controls which endocrine gland?
Parathyroid Pituitary Pancreas Adrenal
A: Pituitary Together, the hypothalamus and pituitary gland serve as the primary link between the nervous system
(hypothalamus) and the endocrine (pituitary gland) system. The pancreas, adrenal, and parathyroid glands are
directly influenced by the pituitary gland, not the hypothalamus.
, Q6: Hormone Regulation and Balance:
A: Overview -The body’s hormones are constantly influenced by internal and external factors, which can sometimes
cause disruptions in normal hormone production and secretion. -This disruption leads to miscommunication between
the hormone and its target cell or organ, triggering a chain reaction aimed at restoring physiologic homeostasis
(balance). Negative Feedback Loop -An internal or external factor causes Gland 1 to produce Hormone A in an effort
to return to homeostasis. -Hormone A stimulates Gland 2 to produce Hormone B. -As Hormone B levels increase,
Gland 1 reduces production of Hormone A. -Gland 2 then reduces production of Hormone B. -When Hormone B
levels drop, Gland 1 begins producing more Hormone A to increase Hormone B levels again.
Q7: Normal Thyroid Function (Euthyroid)
A: Overview -The negative feedback loop is central to maintaining hormonal regulation and balance. -Using a color
wheel as an illustration (see image), each hormone influences and is influenced by others, creating a balance similar
to how colors blend to create harmony. Key Hormones in Thyroid Function (see image) -Thyroid Gland (T3 and T4)
Red → ---Produces triiodothyronine (T3) and thyroxine (T4), which regulate metabolism. -Anterior Pituitary Gland
(TSH) Blue → ---Produces thyroid-stimulating hormone (TSH), which stimulates the thyroid to produce T3 and T4.
-Hypothalamus (TRH) Yellow → ---Produces thyrotropin-releasing hormone (TRH), which prompts the anterior
pituitary to release TSH. Thyroid Function and Balance -The interplay of T3, T4, TSH, and TRH maintains a balanced
thyroid function, known as euthyroid.
