Question 1

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates cortisol secretion by the adrenal cortex

Accepted Answer

ACTH (adrenocorticotropic hormone) is responsible for stimulating cortisol secretion by the adrenal cortex.

Question 2

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all).
-connected to the hypothalamus by a vascular link

Accepted Answer

The answer of Indicate which of the features apply to...

Question 3

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all).
-synthesizes the hormones it secretes

Accepted Answer

The anterior pituitary synthesizes and secretes its hormones, while the posterior pituitary stores and releases hormones synthesized by the hypothalamus. Therefore, option A does not apply to the posterior pituitary, and option C is incorrect because the posterior pituitary does not synthesize hormones, it only stores and releases them.

Question 4

Match the description with the types of bone cells by using the answer code.
-stimulated by growth hormone

Accepted Answer

Osteoblasts are bone cells that are stimulated by growth hormone to produce new bone tissue.

Question 5

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all).
-may be directly inhibited by negative feedback from its target organ

Accepted Answer

The anterior pituitary is directly inhibited by negative feedback from its target organ. The posterior pituitary is not directly controlled by negative feedback.

Question 6

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates testosterone secretion

Accepted Answer

GnRH (Gonadotropin-releasing hormone) stimulates the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) by the anterior pituitary gland. LH stimulates testosterone secretion in males.

Answer: A
 Vasopressin (also known as antidiuretic hormone or ADH) causes water retention in the kidneys, and can also stimulate the release of ACTH (adrenocorticotropic hormone) from the pituitary gland.

Neither oxytocin, TSH, nor growth hormone stimulate testosterone secretion.

Question 7

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-responsible for ovulation

Accepted Answer

The hormone responsible for ovulation is luteinizing hormone (LH), which is not listed as an option.

Question 8

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all). -enhances H₂O retention by the kidneys

Accepted Answer

Vasopressin, also known as antidiuretic hormone (ADH), enhances water retention by the kidneys. H₂O, or water, is retained by the kidneys due to the action of vasopressin.

Question 9

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-exerts a pressor effect on arterioles

Accepted Answer

Vasopressin, also known as antidiuretic hormone, exerts a pressor effect on arterioles by causing their constriction.

Question 10

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all).
-releases primarily tropic hormones into the blood

Accepted Answer

The anterior pituitary gland releases primarily tropic hormones into the blood, which regulate the activity of other endocrine glands. The posterior pituitary gland releases oxytocin and antidiuretic hormone into the bloodstream, which are not necessarily tropic hormones. Therefore, only option B applies to the anterior pituitary gland.

Question 11

Indicate which of the features apply to the posterior and anterior pituitary by using the answer code (options may be used more than once or not at all).
-releases vasopressin and oxytocin into the blood

Accepted Answer

The secretion of vasopressin and oxytocin is regulated by the hypothalamus and they are stored and released from the posterior pituitary. Therefore, this feature applies only to the posterior pituitary. The anterior pituitary releases hormones such as growth hormone and follicle-stimulating hormone.

Question 12

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates uterine contractions

Accepted Answer

Oxytocin is responsible for stimulating uterine contractions during labor and delivery.

Question 13

Match the description with the types of bone cells by using the answer code.
-bone cells that are entombed in bone

Accepted Answer

Osteocytes are the bone cells that are entombed in bone.

Question 14

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-regulates overall body growth

Accepted Answer

Growth hormone is responsible for regulating overall body growth.

Question 15

Match the description with the types of bone cells by using the answer code.
-bone cells that form bone

Accepted Answer

Osteoblasts are responsible for bone formation and depositing osteoid, which eventually becomes mineralized to form bone tissue.

Answer: A
 Osteocytes are the mature bone cells that maintain the bone tissue by recycling and recycling calcium and phosphate ions and providing support to the bone structure.

Answer: C
 Osteoclasts are large cells that dissolve the bone tissue by secreting enzymes and acids to break down the mineralized matrix. They are important in bone resorption and remodeling.

Question 16

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates secretion of thyroid hormone

Accepted Answer

TSH (thyroid stimulating hormone) is specifically responsible for stimulating the thyroid gland to secrete thyroid hormone.

Question 17

Match the description with the types of bone cells by using the answer code.
-bone cells that dissolve bone

Accepted Answer

Osteoclasts are the cells responsible for breaking down bone tissue by dissolving it.

Question 18

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates growth of ovarian follicles and development of eggs

Accepted Answer

GnRH (gonadotropin-releasing hormone) stimulates growth of ovarian follicles and development of eggs.

Note: None of the other hormones listed have a direct role in ovarian follicle or egg development.

Question 19

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates both estrogen and progesterone secretion

Accepted Answer

None of the options listed are responsible for stimulating both estrogen and progesterone secretion. The hormone responsible for this action is luteinizing hormone (LH), which was not listed as an option.

Question 20

Indicate which hormone is responsible for each action by using the answer code (options may be used more than once or not at all).
-stimulates somatomedin secretion by the liver

Accepted Answer

Somatomedin is also known as insulin-like growth factor (IGF-1), which is produced by the liver in response to stimulation by growth hormone. Therefore, the hormone responsible for stimulating somatomedin secretion by the liver is growth hormone (option E).
