GUARANTEED.
What are the three mechanisms of endocrine dysfunction? Answer: Hypofunction,
hyperfunction, and hormone resistance.
What is hypofunction in the context of endocrine disorders? Answer: Hypofunction occurs when
an endocrine gland is underactive, possibly due to gland absence, impaired development, or
damage.
What can cause hyperfunction of an endocrine gland? Answer: Hyperfunction can result from
excessive stimulation, hyperplasia, or ectopic hormone production by tumors.
What is hormone resistance? Answer: Hormone resistance occurs when target cells fail to
respond to hormones due to receptor defects or absence.
What is an example of a primary endocrine disorder? Answer: Addison disease, where
autoimmune damage to the adrenal cortex leads to underproduction of adrenal hormones.
How do secondary endocrine disorders differ from primary disorders? Answer: Secondary
disorders involve normal target glands that do not produce adequate hormones due to lack of
stimulation from the hypothalamus or pituitary gland.
What is the role of the pituitary gland? Answer: The pituitary gland regulates various endocrine
functions by secreting hormones that control other glands.
What hormones are produced by the anterior pituitary? Answer: ACTH, TSH, GH, FSH, LH,
and prolactin.

,What does ACTH regulate? Answer: ACTH controls the release of cortisol from the adrenal
gland.
What is the primary function of TSH? Answer: TSH stimulates the secretion of thyroid
hormones from the thyroid gland.
What are the clinical features of hypopituitarism? Answer: Hypopituitarism can lead to
deficiencies in multiple hormones, affecting growth, metabolism, and reproductive functions.
What is acromegaly? Answer: Acromegaly is a condition caused by excess growth hormone,
leading to enlarged body parts.
What is the significance of glucagon in blood glucose regulation? Answer: Glucagon raises
blood glucose levels by promoting glycogen breakdown in the liver.
What is the dawn phenomenon? Answer: The dawn phenomenon is an increase in blood glucose
levels in the early morning due to hormonal changes.
What are the common acute complications of diabetes? Answer: Common acute complications
include hypoglycemia and diabetic ketoacidosis.
What is the Somogyi effect? Answer: The Somogyi effect is a rebound hyperglycemia following
hypoglycemia, often due to excessive insulin.
What are the chronic complications of diabetes? Answer: Chronic complications include
microvascular effects (like retinopathy and nephropathy) and macrovascular effects (like
cardiovascular disease).
What is metabolic syndrome? Answer: Metabolic syndrome is a cluster of conditions that
increase the risk of heart disease, stroke, and diabetes.
What is the role of insulin in metabolism? Answer: Insulin facilitates the uptake of glucose, fats,
and proteins, regulating energy metabolism.

, How is diabetes mellitus classified? Answer: Diabetes mellitus is classified into prediabetes,
type 1, type 2, gestational diabetes, and diabetes due to other causes.
What is the primary function of adrenal cortical hormones? Answer: Adrenal cortical hormones
regulate metabolism, immune response, and stress response.
What is congenital adrenal hyperplasia? Answer: Congenital adrenal hyperplasia is a disorder
where the adrenal gland cannot produce cortisol due to enzyme defects.
What is the infundibulum? Answer: The infundibulum is the stalk that connects the pituitary
gland to the hypothalamus.
What hormones are secreted by the posterior pituitary? Answer: The posterior pituitary secretes
antidiuretic hormone (ADH) and oxytocin.
What is the relationship between the hypothalamus and the pituitary gland? Answer: The
hypothalamus regulates the pituitary gland, which in turn controls other endocrine glands.
What is Laron syndrome? Answer: Laron syndrome is a rare dwarfism caused by a mutation in
the growth hormone receptor, leading to hormone resistance.
What hormones are produced by the anterior lobe of the pituitary gland? Answer: ACTH, TSH,
GH, LH, FSH, and prolactin.
What does ACTH control? Answer: The release of cortisol from the adrenal gland.
What is the function of TSH? Answer: It controls the secretion of thyroid hormone from the
thyroid gland.
What role does LH play in the body? Answer: It regulates sex hormones in the ovaries and
testes.
What is the function of FSH? Answer: It regulates fertility in the ovaries and testes.
