BIOL 2402 Lecture Exam 1 Questions | 2026/2027 | Answers
Correct | With Complete Solutions
Growth hormone (GH)
Structure that Releases it: Anterior Pituitary
Function: stimulates release of IGFs from the liver, which
synergistically acts on all body tissues to stimulate growth
Stimuli type: Hormonal
Luteinizing hormone (LH)
Structure that Releases it: Anterior Pituitary
Function: act on gonads to stimulate development of gametes
and release hormones
Stimuli type: Hormonal
Oxytocin
Structure that Releases it: Posterior Pituitary
Function: in both delivery of a baby and ejection of milk in
females
Stimuli type: Nervous System
Prolactin (PRL)
Structure that Releases it: Anterior Pituitary
Function: acts on mammary glands to influence gland growth
and stimulate milk production
Stimuli type: Hormonal
Thyroid hormone (TH)
,Structure that Releases it: Thyroid gland
Function: increase metabolism and cause a release of nutrients
into the blood
Stimuli Type: Hormonal
Graves' disease
An autoimmune disorder involving the formation of
autoantibodies that mimic TSH hormone, which causes an
overproduction of TH
Aldosterone
Structure that releases it: Zona Glomerulosa (Adrenal Gland)
Function: regulates the ratio of NA+ and K+ in our blood and
body fluids by altering the amounts excreted by the kidney into
the urine
Stimuli Type: Humoral
Epinephrine
Structure that releases it: Adrenal Medulla (Adrenal Gland)
Function: help prolong the fight-or-flight response
Stimuli Type: Nervous
Glucocorticoids
Structure that releases it: Zona Fasciculata (Adrenal Gland)
Function: regulate glucose levels
Stimuli Type:Humoral
Cushing syndrome
, Caused by a chronic exposure of the body's tissues to excessive
levels/adrenal gland overproduction of glucocorticoid hormones,
characterized by body obesity, in the face and back.
Glucagon
Structure that releases it: Pancreatic Islets (Alpha Cells)
Function: increase glucose, glycerol, and fatty acids in the blood
Stimuli Type: Humoral
Insulin
Structure that releases it: Pancreatic Islets (Beta Cells)
Function: decrease glucose levels
Stimuli Type: Humoral
Diabetes Type 1
Insulin-dependent, absent or diminished production and release
of insulin by the beta cells of the pancreatic islets, often
triggered by a viral infection leading to an autoimmune
condition in which pancreatic islets are destroyed.
Melatonin
Structure that releases it: Pineal Gland
Function: regulates circadian rhythm
Stimuli Type: Nervous
Parathyroid hormone (PTH)
Structure that releases it: Parathyroid (Chief Cells)
Function: increase blood calcium levels
Stimuli Type: Humoral
Physical Characteristics of Blood
