Which hormones have a general role in body metabolism, including maintaining blood pressure, regulating tissue growth, developing skeletal and nervous systems during childhood, and maturation and reproductive capabilities?
Calcitonin
Growth Hormone
T3 and T4
ADH
Progesterone
The posterior pituitary is also known as neurohypophysis because it stores hormones secreted by hypothalamus neurons.
True
False
Cretinism, a specific type of dwarfism, is caused by hyposecretion?
T3 and T4
Progesterone
LH
Growth Hormones
Under secretion of ADH can cause diabetes I.
True
False
___________ is responsible for milk production, while _____________ is responsible for milk projection (letdown).
PTH; Calcitonin
Prolactin; Oxytocin
Prolactin; LH
Insulin; Glucagon
ADH; Oxytocin
What is not a function of the parathyroid hormone (PTH)?
Its production is stimulated by a decrease in blood calcium levels
Increase formation of vitamin D
Increases Ca2+ reabsorption by the kidneys
Decrease osteoclasts activity
Inhibits osteoblasts
If you have a decrease in blood volume or blood pressure, your body will likely start the release of ADH and __________________.
Melatonin
Prolactin
Aldosterone
Growth Hormone
Oxytocin
This hormone is related to pregnancy as it targets the mother's uterus, by enhancing contraction of smooth muscle cells in uterine wall and dilation of the cervix (positive feedback) and milk ejection (let-down), in response to sucking by infant.
Melatonin
Oxytocin
ADH
PTH
Insulin
Above is a list of functions of the Endocrine System. Which hormone is the major responsible for #3?
Melatonin
T3
ADH
Calcitonin
Insulin
In children, hyper secretion of growth hormone can cause excessive growth, mainly caused by continuous hyperglycemia. This condition is known as Giantism.
True
False
Parathyroid hormone increases blood calcium levels when they drop too low. Conversely, (a) , which is released from the thyroid gland, decreases blood calcium levels when they become too high. These two mechanisms constantly maintain blood calcium concentration at homeostasis, and these two hormones are antagonistic hormones regarding their effects on blood calcium levels.
Diabetes Insipidus is caused by undersecretion of (a) , or due to the inability of the kidney to respond to it.
Secretion of ______ and ______ hormones prepares the body for physical activity (fight/flight) by:
Insulin and T3
Melatonin and Epinephrine
LH and Progesterone
Epinephrine and Noepinephrine
No hormone is produced during fight or flight situations
Adipose Tissue produces leptin, which increases and decreases in response to the amount of present body fat. When secreted, it influences energy intake and expenditure by binding to brain neurons causing a decrease in apetite.
True
False
Atria of the heart produces atrial-natriuretic peptide (ANP) hormone when blood pressure is low by targeting the kidneys to increase Na+ reabsorption; so, it will promote an increase in blood pressure and blood volume.
True
False
The zona glomerulosa of the adrenal gland produces a hormone that is responsible for the control ion balance in the body. This hormone is:
Aldosterone
ADH
Cortisol
PTH
Select the correct statement regarding the glucocorticoids.
Cortisol provokes gluconeogenesis
Excessive levels of glucocorticoids increase cartilage and bone formation
Cortisol decreases blood sugar levels
Cortisol provokes lipogenesis
What option is not correct about androgens?
Androgens contribute to sex drive in females
Androgens contribute to the production of milk during pregnancy
Androgens contribute to the onset of puberty
Androgens contribute to the appearance of secondary sex characteristics
Hormones released by the adrenal cortex are responsible for the fight or flight responses.
True
False
The hormone produced by the Pineal Gland, helps regulate sleep-wake cycle.
Growth Hormone
Testosterone
Melatonin
T3
Which fact about the pancreas is NOT true?
99% of the pancreatic cells produce enzymes and 1% produce hormones
It has both Endocrine and Exocrine functions
Is located posterior to the stomach
Alpha cells of the pancreas produces insulin
The two hormones that control glucose levels in the blood are:
Melatonin and Insulin
T3 an Aldosterone
Insulin and Glucagon
ADH and cortisol

What this video and answer the question
In type I diabetes we have no insulin. So, the person who has type I diabetes has no insulin production. And because of that, the person is not able to store sugar and glycogen, making glucose to be all over the place in our body (remember, insulin binds to receptors in the cell membrane, which allow glucose to enter the cell), which will cause eye nerve an kidney disease very common complications.
In type II diabetes, insulin is produced, but the insulin (a) are broken. So even if we do produce insulin, and it goes where it is supposed to go in our body, the cells will not be able to take in glucose.
Caused by hypersecretion of cortiso;
High blood glucose levels, lipid deposits on the face and neck, moon-shaped face, hump on back of neck, rapid weight gain, hair loss;
May lead to Type II Diabetes;
Causes: pituitary tumor that secretes cortisol or ACTH;
Name the disease.
(a)
