Which of the following is not involved in the regulation of the reproductive system? adrenal gland hypothalamus anterior pituitary testes/ovaries nervous system

How many iodine atoms are in thyroxine? one two three four five

How are the posterior pituitary and anterior pituitary similar? Both are controlled by the hypothalamus. Both produce three or more hormones. Both are connected to the hypothalamus via a portal system. Both produce releasing and inhibiting hormones. Both produce hormones that control other glands.

Which of the following statements is not true concerning the hypothalamus? The hypothalamus acts as the link between the nervous and endocrine systems. The hypothalamus regulates the internal environment of the body. The hypothalamus communicates with the somatic nervous system. The hypothalamus controls the glandular secretions of the pituitary gland. The hypothalamus produces antidiuretic hormone and oxytocin.

Which of the following is a feature of an endocrine gland? secretes a hormone directly into the bloodstream secretes a hormone into a gland or duct the product of these glands is carried into the lumen of an organ characterized by the salivary glands they do not respond to a negative feedback system

Which of the following organs also produce hormones as a secondary function of the organ? heart testes ovaries adrenal cortex thyroid

Which of the following does not act to increase the amount of calcium in the blood? bones calcitonin kidneys intestines parathyroid hormone

How are the nervous system and the endocrine system alike? They both utilize axons and synapses. They both regulate the activities of other systems. They both utilize glands. They both respond very rapidly to stimuli. They both have an very prolonged response to stimuli.

A person with congenital hypothroidism will exhibit what symptoms? myxedema exopthalmic goiter simple goiter short and stocky, possible mental retardation tetany

Which organ does not produce steroid hormones? pineal gland adrenal cortex ovaries testes

Which of the following hormones is not produced by the anterior pituitary? prolactin growth hormone thyroid stimulating hormone adrenocorticotropic hormone oxytocin

Which of the following is not an endocrine gland? duodenum pituitary adrenal pineal thymus

Which pancreatic hormone will be secreted when blood glucose levels are high? insulin glucagon cortisol thyroxine antidiuretic hormone

Which of the following is not a symptom of Addison disease? low blood pressure bronzing of the skin mild infections can lead to death loss of sodium and water increased blood sugar levels

Which of the following statements is not true about growth hormone? Growth hormone is produced by the posterior pituitary. The quantity of growth hormone is greatest during childhood and adolescence. Too little growth hormone results in dwarfism. Too much growth hormone results in giantism. Growth hormone can be administered as a medical treatment for stature problems.

Which of the following is a result of mineralocorticoid release? Glucose is not broken down. The immune cells are suppressed. Inflammation is reduced. Proteins and fat are broken down. Blood volume and pressure increase.

Jamie suffers from heartburn. Sometimes this can be treated with mineralocorticoids. prostaglandins. aldosterone. thymosin. luteinizing hormone.

Damage or a tumor to which organ would lead to a disruption of the nervous and endocrine system? hypothalamus pituitary lymph nodes frontal lobe of the brain pineal gland

Which of the following hormones is mismatched with its producing gland? ovaries--follicle-stimulating hormone ovaries--estrogen thymus gland--thymosins pineal gland--melatonin testes--androgens

Which system does the hypothalamus belong to? the nervous system the endocrine system both the nervous and the endocrine systems reproductive system cardiovascular system

Which of the following is an exocrine gland? parathyroids salivary glands thymus testes adrenal gland

Where are the adrenal glands located? in the brain in the neck on top of the kidneys near the ovaries/testes near the small intestine

The secretion of which hormones qualifies the pancreas as an endocrine gland? insulin and glucagon insulin and digestive juices digestive juices and glucagon mineralocorticoids and insulin estradiol and digestive juices

When insulin is secreted, what happens? Tissue stores of glucose are depleted. Adipose tissue breaks down fat. The liver breaks down glycogen. The blood glucose level rises. Glucose is taken up by the cells.

CH. 17 The development of a hard chancre (an ulcerated sore with hard edges) is indication of what type of STD? hepatitis papillomavirus syphilis yeast infection gonorrhea

Following ovulation, the follicle becomes the corpus luteum and produces sex hormones. disappears immediately. becomes a vesicular or Graafian follicle. becomes a secondary follicle containing a secondary oocyte. becomes a polar body

What does being overweight have to do with infertility in women? Leptin levels are higher which impacts GnRH and FSH. The oviducts are blocked. Uterine tissue is located outside of the uterus causing pain and structural abnormalities. Follicles are larger than normal and many mature at one time. The uterus is displaced and the zygote has difficulty implanting.

Which of the following statements is not true concerning the hormonal control over the male reproductive system? The hypothalamus secretes a hormone called gonadotropin-releasing hormone. Follicle-stimulating hormone and luteinizing hormone are present in both males and females. These hormones are involved in a negative feedback relationship. Luteinizing hormone controls the production of sperm in the seminiferous tubules. The interstitial cells produce testosterone

Which of the following hepatitis viruses is normally transmitted through contaminated drinking water? Which of the following hepatitis viruses is normally transmitted through contaminated drinking water? A B C D G

What causes genital warts? bacteria virus fungi parasite molds

Which layer of the endometrium is the functional layer and what does it do? the innermost layer, basal layer of reproducing cells the innermost layer, grows in thickness to accommodate the pregnancy the outermost layer, basal layer of reproducing cells the outermost layer, grows in thickness to accommodate the pregnancy the middle layer is shed frequently to maintain a healthy lining for implantation

Which of the following is not part of the male reproductive system? testes bladder epididymides prostate gland urethra

Which of the following statements is not true concerning the estrogen spike at the end of the follicular phase? It has a positive feedback effect on the hypothalamus. It has a positive feedback effect on the pituitary gland. Gonadotrophic releasing hormone from the hypothalamus decreases. It is followed by a surge of LH. It is followed by ovulation.
