Hormones

Question 1

Principle Hormones of the Hypothalamus

Answer 1

Corticotropin-releasing hormone (CRH)
Thyrotropin-releasing hormone (TRH)
Gonadotropin-releasing hormone (GRH)
Growth hormone-releasing hormone (GHRH)
Growth hormone-inhibiting hormone (somatostatin GHIH)
Prolactin-inhibiting hormone (PIH)
Melanocyte-inhibiting hormone (MIH)

Question 2

Principle Hormones of the Anterior Pituitary

Answer 2

Thyroid-stimulating hormone (TSH, thyrotropin) [synthesis/release of thyroid hormone]
Adrenocorticotropic hormone (ACTH, corticotropin) [synthesis/release of corticosteriods and adrenocortical growth]
Lutenizing hormone (LH, Leydig cell-stimulating hormone [LCSH]) [ovulation/progesterone secretion, testosterone secretion]
Follicle-stimulating hormone (FSH) [estrogen secretion/follicle maturation, spermatogenesis]
Prolactin (PRL) [breast milk production]
Growth hormone (GH) [bone/soft tissue growth]
Melanocyte-stimulating hormone (MSH) [pigmentation]

Question 3

Principle Hormones of the Anterior Pituitary

Answer 3

Vasopressin (antidiuretic hormone, ADH) [promotes water reabsorption in kidney]
Oxytocin [stimulates uterine contractions and ejection of breast milk]

Question 4

Principle Hormones of the Adrenal Cortex

Answer 4

[Adrenal steroids/corticosteriods]
Glucocorticoids (cortisol)
Mineralocorticoids (aldosterone)

Question 5

Principle Hormones of the Adrenal Medulla

Answer 5

Norepinephrine [acts mainly on alpha-adrenergic receptors]
Vasoconstriction
Increased GI sphincter tone
Increased bladder sphincter contractions
Increased sweating
Increase liver gluconeogenesis and glycogenolysis
Decrease pancreatic glucagon and insulin release
Dilation of pupils
Epinephrine [acts mainly on beta-andrenergic receptors]
Increased heart rate and contractility
Vasodilation
Decreased GI motility
Increased renin release
Bronchiole relaxation/dilation
Relaxation of detrusor muscle in bladder
Increased lipolysis
Increased pancreatic glucagon and insulin release
