A&P II - UTA BIOL 2458 - EXAM 1 QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2026
Endocrine System Mode... - Answers Blood borne and its messengers are hormones
Endocrine System... - Answers Slow compared to the nervous system
Anterior Pituitary... - Answers Hormone release stimulated by releasing and inhibiting hormones from
the hypothalamus. Regulated by negative feedback. Hypothalamic hormones made by neurosecretory
cells transported by hypophyseal portal system.
Hormones of the Anterior Pituitary... - Answers HGH,
Prolactin,
Luteninzing,
Follicle Stimulating Hormone,
Melanocyte Stimulating Hormone,
Thyroid Stimulating Hormone,
ACTH
HGH or Human Growth Hormone... - Answers Stimulates secretion of insulin-like growth factors (IGFs)
that promote growth, and protein synthesis
TSH or Thyroid Stimulating Hormone... - Answers Stimulates synthesis and secretion of thyroid
hormones by thyroid
FSH or Follicle Stimulating Hormone... - Answers Ovaries initiate development of oocytes; testes
stimulate testosterone production
Luteinzing Hormone... - Answers Ovaries stimulate ovulation; testes stimulate testosterone
production
Prolactin PRL... - Answers Promotes milk secretion by mammary glands
ACTH or Adrenocorticotropic Hormone... - Answers Stimulates glucocorticoid secretion by adrenal
cortex
MSH or Melanocyte Stimulating Hormone... - Answers Uncertain complete role probably regulates
skin pigmentations
Posterior Pituitary... - Answers Does not synthesize hormones. Stores and releases hormones made by
the hypothalamus
Oxytocin... - Answers During and after delivery of baby affects uterus and breasts. Enhances smooth
muscle contraction in wall of uterus. Stimulates milk ejection from mammary glands.
ADH... - Answers Decreases urine production by causing the kidneys to return more water to the
blood. Decreases water lost through sweating and constriction of arterioles which increases blood
pressure.
Thyroid Glands... - Answers Produces Thyroxins and Calcitonin.
Throxin T3 and T4... - Answers Both increase BMR, stimulate protein synthesis, increase use of glucose
and fatty acids for ATP production.
Calcitonin... - Answers Produced by C cells in the thyroid they decrease blood calcium level.
Parathyroid Hormone... - Answers Secreated by parathyroid glands its a major regulator of calcium,
magnesium and phosphate ions in the blood. Increases number and activity of osteoclasts thereby
elevates bone resorption.
Adrenal Medulla... - Answers Releases epinephrine and norephinephrine. Increases sympathetic
responses.
Adrenal Cortex... - Answers 3 mineralcorticoids: Aldosterone, Androgens and Glucocorticoids.
Aldonsterone... - Answers Retains sodium in exchange for potassium.
Androgens... - Answers Masculinizing effects.
Gucocortcoids... - Answers Affect glucose homeostasis using hormones using cortisol.
Ovaries... - Answers Produce estrogen and progesterone.
Testes... - Answers Produces testosterone which regulates sperm production and secondary male
characteristics.
Pineal Gland... - Answers Releases melatonin which regulates sleep.
Thymus... - Answers Its hormones help T cells mature. In children trains cells to attack, as you get
older it becomes less and less useful (involution).
Water Soluable... - Answers Binding of hormone to its receptor activates G protein which activates a
secondary messenger.
Lipid Soluable... - Answers Into the cell and cal alter DNA quickly.
