Teratoma in the pituitary gland is a very rare tumor that occurs in children and young adults. Usual symptoms of teratoma are diabetes insipidus, neurological issues, and a reduction in pituitary hormones. Which of the following correctly describes the symptoms of a 10 years old girl with a teratoma tumor in the pituitary gland. Select one: A. Increased levels of ADH and stimulation of the development of secondary sexual characteristics. B. Increased levels of FSH and inhibition of the development of secondary sexual characteristics. C. Decreased levels of ADH and inhibition of the development of secondary sexual characteristics. D. Decreased level of FSH and stimulation of the development of secondary sexual characteristics.

Identify two factors that could influence the nutrients that can pass from the mother to the fetus, and identify the group of hormones that alter cell membrane receptors and explain how this alternation can affect cell function.
The pituitary gland starts sending out hormones into the blood stream to initiate puberty, as is seen in the image. Which of the following statements best describes what the image is showing about how those hormones are received by the organs associated with puberty? The hormones circulate all over the body and act upon every cell. The hormones are dispersed to a specific area of the body and bind to target cells there. The hormones are dispersed and received only by cells in range of the signal before they degrade. The hormones circulate all over the body and bind to specific receptors that only target cells possess.
Figure 16.14 Goiter, a disease caused by iodine deficiency, results in the inability of the thyroid gland to form T3 and T4 . The body typically attempts to compensate by producing greater amounts of TSH. Which of the following symptoms would you expect goiter to cause? a. Hypothyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. b. Hyperthyroidism, resulting in weight loss, profuse sweating and increased heart rate. C. Hyperthyroidism, resulting in weight gain, cold sensitivity, and reduced mental activity. d. Hypothyroidism, resulting in weight loss, profuse sweating and increased heart rate.

Asian Americans d. Hispanic Americans
Which of the following hormones is not matched correctly to its effect on the mother?a. peptide hormones—increased resistance to insulinb. progesterone—reduced chances of the mother having an immunereaction to the fetusc. estrogen—increased uterine blood flowd. progesterone—relaxation of smooth muscle and decrease inblood pressuree. All of these are matched correctly
A woman is in labor. The size of the fetus combined with the contractions of the uterine muscular layer stretches the uterine wall, stimulating stretch receptors in the cervix. Signals from these receptors are conducted through nerves to the hypothalamus/posterior pituitary. The hypothalamus/posterior pituitary releases oxytocin. The oxytocin travels through the blood and stimulates the smooth muscle layer of the uterus. Oxytocin has two effects on the uterine smooth muscle: It directly stimulates the smooth muscle to contract more frequently and more It causes the uterine wall to release prostaglandins, which increase the frequency and force of These effects push the fetus more forcefully into the cervix, stimulating the stretch receptors further. The receptors send additional impulses to the hypothalamus/posterior pituitary. The increased activation of the hypothalamus/posterior pituitary stimulates release of additional oxytocin, which further stimulates the uterus. This cycle of…

1. The pituitary gland is made of three lobes. The anterior lobe in larvae and young adults secretes the growth-stimulating hormones which in turn regulate growth and affects the function of the thyroid gland. In adults, it secretes the gonad stimulating hormone that is responsible for the release of ova and sperm from the ovary and testes, respectively. The intermediate lobe produces intermedin or the melanocyte-stimulating hormone, which regulates the behavior of the chromatophores in the skin. The posterior lobe secretes vasopressin or the antidiuretic hormone, which regulates water intake by the skin. 2. The pineal gland, located between the optic lobes and the anterior olfactory lobes, produces melatonin, a hormone that controls the Circadian rhythms and reproductive cycles. 3. The endocrine glands located outside the brain include the thyroid gland, pancreas, adrenal gland, and the gonads (testes and ovaries). The thyroid gland, located behind the hyoid cartilage, produces the…
The hypothalamus regulates many different of metabolic, developmental, and autonomic nervous system functions. For example, the hypothalamus produces ____ during puberty. FSH (follicle-stimulating hormone) and LH (luteinizing hormone) estrogen and testosterone GnRH (gonadotropin-releasing hormone)
