When a hormone is present in excessive levels, the number of target-cell receptors may decrease. This is called:
-
Circulating hormone
-
Down regulation
-
Up regulation
-
Receptor recognition
-
Paracrine
Correct Answer
A. Down regulationExplanation
When a hormone is present in excessive levels, the number of target-cell receptors may decrease. This is known as down regulation. In this process, the target cells reduce the number of receptors on their surface in response to the high concentration of the hormone. This down regulation helps to prevent overstimulation of the target cells and maintains homeostasis in the body.Rate this question:

Which of the following is a major eicosanoid?
-
Prostaglandins
-
Leukotrienes
-
Glycoproteins
-
Both a and b
-
All of the above
Correct Answer
A. Both a and bExplanation
Both prostaglandins and leukotrienes are major eicosanoids. Eicosanoids are signaling molecules that are derived from arachidonic acid, a fatty acid found in cell membranes. Prostaglandins and leukotrienes play important roles in inflammation, immune response, and various physiological processes. Prostaglandins are involved in regulating blood flow, hormone regulation, and inflammation, while leukotrienes are involved in allergic and inflammatory reactions. Therefore, the correct answer is "Both a and b."Rate this question:

Which of the following is not a way hormone secretion is regulated.
-
Signals from the nervous system
-
Chemical changes in the blood
-
Signals from the peripheral nervous system
-
The action of other hormones
-
Both a and b
Correct Answer
A. Signals from the peripheral nervous systemExplanation
Hormone secretion is regulated by various factors, including signals from the nervous system and chemical changes in the blood. The peripheral nervous system is not directly involved in regulating hormone secretion. Instead, it is the central nervous system that plays a role in regulating hormone release. Therefore, signals from the peripheral nervous system are not a way hormone secretion is regulated.Rate this question:

Which of the following anterior pituitary hormones stimulates Cortisol production?
-
Adrenocorticotropic hormone
-
Insulin like growth factors
-
Luteinizing hormone
-
Prolactin
-
Melanocyte stimulating hormone
Correct Answer
A. Adrenocorticotropic hormoneExplanation
Adrenocorticotropic hormone (ACTH) is secreted by the anterior pituitary gland and stimulates the production of cortisol by the adrenal cortex. Cortisol is a steroid hormone that plays a crucial role in regulating metabolism, immune response, and stress response. ACTH binds to receptors on the adrenal cortex, triggering the release of cortisol. Therefore, ACTH is the hormone responsible for stimulating cortisol production.Rate this question:

Which of the following anterior pituitary hormones stimulates sex cell production?
-
Luteinizing hormone
-
Corticotropin
-
Melanocyte stimulating hormone
-
Growth hormone
-
TSH
Correct Answer
A. Luteinizing hormoneExplanation
Luteinizing hormone is the correct answer because it stimulates the production of sex cells, specifically in males, it stimulates the production of testosterone in the testes, and in females, it stimulates ovulation and the production of progesterone and estrogen in the ovaries. Corticotropin, melanocyte stimulating hormone, growth hormone, and TSH do not directly stimulate sex cell production.Rate this question:

How many hormones do the five types of anterior pituitary cells secrete?
-
7
-
10
-
12
-
Unlimited
-
5
Correct Answer
A. 7Explanation
The five types of anterior pituitary cells secrete a total of 7 hormones. This suggests that each type of cell is responsible for secreting at least one hormone, with some cells potentially secreting more than one. The answer of 7 indicates that there are a limited number of hormones secreted by these cells, rather than an unlimited amount.Rate this question:

Which hormones does the posterior pituitary release?
-
Melatonin stimulating hormone and Oxytocin
-
Oxytocin and Antidiuretic hormone
-
Follicle stimulating hormone and Thyroid stimulating hormone
-
Prolactin and ACTH
-
Prolactin and Human Growth hormone
Correct Answer
A. Oxytocin and Antidiuretic hormoneExplanation
The posterior pituitary gland releases two hormones: oxytocin and antidiuretic hormone (ADH). Oxytocin is responsible for stimulating contractions during childbirth and promoting bonding and social behavior. ADH, also known as vasopressin, helps regulate water balance in the body by reducing urine production and increasing water reabsorption in the kidneys.Rate this question:

Which of the following hormones opposes the action of parathyroid hormone?
-
Thyroid stimulating hormone
-
Testosterone
-
Insulin
-
Calcitonin
-
Calcitriol
Correct Answer
A. CalcitoninExplanation
Calcitonin is the hormone that opposes the action of parathyroid hormone. Parathyroid hormone is responsible for increasing calcium levels in the blood, while calcitonin decreases calcium levels. Therefore, calcitonin works in opposition to parathyroid hormone by inhibiting the release of calcium from bones and promoting calcium excretion by the kidneys.Rate this question:

Which of the following is not part of the process used to synthesize and secrete T3 and T4?
-
Iodide trapping
-
Oxidation of iodide
-
Coupling of T1 and T2
-
Hydrolysis of calcium
-
Iodination of tyrosine
Correct Answer
A. Hydrolysis of calciumExplanation
Hydrolysis of calcium is not part of the process used to synthesize and secrete T3 and T4. The synthesis of T3 and T4 involves several steps, including iodide trapping, oxidation of iodide, coupling of T1 and T2, and iodination of tyrosine. Calcium hydrolysis, on the other hand, refers to the breakdown of calcium compounds into calcium ions and hydroxide ions, which is not directly involved in the synthesis and secretion of thyroid hormones.Rate this question:
