By which receptor model would aldosterone likely affect its targets? | Mobile/intracellular receptor model |
Name the hormones described: Increased blood sugar by gluconeogenesis | Glucagon, Cortisol |
Name the hormones described: Low levels in infancy result in mental retardation | T3 (Thyroxine), T4 (Triiodothyronine) thyroid hormones |
Name the hormones described: Increases blood calcium | Parathyroid hormone |
Name the hormones described: Stimulates contraction of uterine smooth muscle | Oxytocin |
Name the hormones described: Decrease blood potassium | Aldosterone |
Name the hormones described: Decrease the sensitivity of targets to catecholamines | Thyroxine (T4) |
Secreted by neuron of the hypothalamus (Name the hormones described A-F below. Choose your answers from the list provided.) | A. |
Stimulates cells of the kidney to reabsorb water (Name the hormones described A-F below. Choose your answers from the list provided.) | Anti-diuretic Hormone |
Under tonic inhibition (Name the hormones described A-F below. Choose your answers from the list provided.) | Prolactin |
Stimulates emptying of the mammary gland (Name the hormones described A-F below. Choose your answers from the list provided.) | Oxytocin |
Affects mitosis of the epiphyseal disc. (Name the hormones described A-F below. Choose your answers from the list provided.) | Luteinizing Hormone |

Which portion of the pituitary differentiates from Rathke’s pouch? | Adenohypophysis |
What is the function of the hypothalamic-hypophyseal portal system? | Ensures that concentration of RF or RIF is HIGH enough to stimulate target cells |
A steroid hormone is likely to affect its target via the _______ receptor model. | Mobile/intracellular |
Rathke’s pouch gives rise to all components of the ________ | Adenohypophysis |
The nerve cell bodies of cells secreting oxytocin are located _______ | Hypothalamus |
Name the hormones described below: stimulate contraction of myoepithelial cells in the lacating mammary gland | Oxytocin |
Name the hormones described below: increase blood sugar | Glucagon, Cortisol, Epinephrine |
Name the hormones described below: secreted in response to an increase in blood osmolarity | Antidiuretic Hormone |
Name the hormones described below: low levels result in growth and mental retardation | T3 and T4 Thyroid Hormones |
Name the hormones described below: low levels result in diabetes insipidis | ADH |
Name the hormones described below: inhibit secretion of insulin, glucagons, growth hormone | Somatostatin |
Why is a low level of aldosterone dangerous? | Aldosterone helps regulate sodium and potassium levels in the body. This helps control blood pressure and the balance of fluids and electrolytes in the blood. |
Antidiuretic hormone and oxytocin are secreted from neurons whose nerve cell bodies are located in _________. | Hypothalamus |
In normal physiology, antidiuretic hormone is secreted in response to A. ___________ and cause the kidney to B. ___________ | A. Increase in blood osmolarity sensed by neurons of brain, LOW blood volume sensed by stretch receptors in right atrium and baroreceptors in aorta, pulmonary and carotid aa. B. Reabsorbs H2O |
In females, it appears that __________ (hormone) is important in the stress reaction. | Oxytocin |
In which receptor model does the hormone have a direct effect on the target's DNA? | Mobile receptor/Intracellular receptors |
Which one of the following is NOT likely with decreased insulin levels? ketosis, acidosis, tachypnea, starvation of the CNS, glucosuria, all are likely? | starvation of the CNS |
