precise well set out researched answers !!!
What are the primary features that characterize hormones? - ANSWER💫✔️--Control via the
hypothalamic-pituitary axis, feedback loops, patterns of secretion/metabolism/elimination, receptor
binding, and action on target organs and glands.
How does the hypothalamic-pituitary axis regulate hormone levels? - ANSWER💫✔️--Stimuli reach the
hypothalamus, which triggers the anterior pituitary to release hormones (TRH, CRH, GNRH, GHRH); the
pituitary then responds by producing hormones like ADH and oxytocin.
What is the role of the autonomic nervous system in the stress response? - ANSWER💫✔️--It increases
heart rate, blood pressure, respiratory rate, pupil dilation, and sweating, while shunting blood to vital
organs and decreasing gastric function.
What is the function of the cerebral cortex during the stress response? - ANSWER💫✔️--It regulates
cognitive activities such as intense focus, planning, attention, and persistence.
,What is the function of the limbic system during the stress response? - ANSWER💫✔️--It regulates
emotions like fear, anxiety, anger, and excitement, and stimulates the reticular activating system.
What is the function of the thalamus during the stress response? - ANSWER💫✔️--It intensifies sensory
input related to the stressor, such as vision, hearing, and smell.
What is the function of the reticular activating system during the stress response? - ANSWER💫✔️--It
increases alertness and muscle tension and contributes to the stimulation of the autonomic nervous
system.
What are the primary mechanisms of impairment in hormonal and metabolic regulation? -
ANSWER💫✔️--Damage to the hypothalamic-pituitary axis, damage to endocrine glands, damage to cell
receptors, and damage to feedback mechanisms.
What is the most common etiology of Syndrome of Inappropriate Antidiuretic Hormone (SIADH)? -
ANSWER💫✔️--A tumor elsewhere in the body secreting ectopic ADH.
What is the pathophysiology of SIADH? - ANSWER💫✔️--Excessive production and release of ADH despite
serum osmolarity and blood volume changes, promoting water retention by increasing nephron
permeability.
What are the clinical manifestations of severe SIADH? - ANSWER💫✔️--Psychosis, gait disturbances,
seizures, and coma.
What are the primary causes of Diabetes Insipidus? - ANSWER💫✔️--Impaired hypothalamic
osmoreceptors, chronic renal insufficiency, lithium toxicity, hypercalcemia, or hypokalemia.
What is the pathophysiology of Diabetes Insipidus? - ANSWER💫✔️--Insufficient ADH
production/secretion or inadequate kidney response to ADH, leading to an inability to concentrate or
retain water.
What are the clinical manifestations of Diabetes Insipidus? - ANSWER💫✔️--Polyuria, polydipsia, and
dehydration, which can lead to shock and death if untreated.
, What is the pathophysiology of Graves' disease? - ANSWER💫✔️--IgG antibodies bind to TSH receptors
on thyrocytes, causing excess stimulation of the thyroid gland.
List three common clinical manifestations of hyperthyroidism. - ANSWER💫✔️--Weight loss, heat
intolerance, and tachycardia.
What are the common causes of hypothyroidism? - ANSWER💫✔️--Congenital or acquired factors
including lack of thyroid gland development, deficient synthesis of TH, destruction of the thyroid gland,
or impaired secretion of TSH or TRH.
List three common clinical manifestations of hypothyroidism. - ANSWER💫✔️--Fatigue, weight gain, and
cold intolerance.
What are the primary etiologies of Cushing Syndrome? - ANSWER💫✔️--Long-term corticosteroid
medication, pituitary tumors (excess ACTH), adrenal tumors (excess cortisol), or ectopic production of
ACTH/CRH.
What is the pathophysiology of Cushing Syndrome? - ANSWER💫✔️--Prolonged exposure to elevated
levels of endogenous or exogenous glucocorticoids leading to suppression or overstimulation of cortisol.
What are the clinical manifestations of Cushing Syndrome? - ANSWER💫✔️--Metabolic alterations,
excessive circulating glucose, glucose intolerance, suppressed immune/inflammatory responses, and
behavioral changes.
What is the etiology of Addison Disease? - ANSWER💫✔️--Insufficient production of cortisol and
aldosterone.
What is the pathophysiology of Addison Disease? - ANSWER💫✔️--Autoimmune destruction of the
adrenal cortex layers, resulting in a failure to produce glucocorticoids, mineralocorticoids, or androgens.
What are the clinical manifestations of Addison Disease? - ANSWER💫✔️--Hyperpigmentation,
hypotension, shock, and death.
