Two hypothalamic hormones control growth hormone synthesis and secretion in the anterior pituitary gland. Growth hormone–releasing hormone (GHRH) and: a. IGF-I. b. thyroid hormone. c. leptin. d. somatostatin. e. thyroid-stimulating hormone. ANS: D Somatostatin, or growth hormone–inhibiting hormone (GHIBH), inhibits the secretion of both GHRH and thyroid-stimulating hormone (TSH). TOP: Discipline: Physiology MSC: Organ System: Endocrine 2. Which hormone is known as the “hunger hormone”? a. Leptin b. IGF-I c. Ghrelin d. Somatostatin e. TSH ANS: C Ghrelin, a peptide, known as the “hunger hormone,” helps control growth hormone release and influences food intake and obesity development.

After 50 years of age, stature: a. becomes fixed. b. begins a barely perceptible secondary increase. c. increases at a rate of 0.5 cm/year. d. declines. e. declines and then begins a barely perceptible increase. ANS: D As an individual reaches 50 years of age, the intervertebral disk begins to thin and becomes more compressed, which leads to a decline in stature. TOP: Discipline: Physiology MSC: Organ System: Musculoskeletal 4. By 10 to 12 years of age, lymphatic tissues are about _____ adult size. a. 25% of b. 50% of c. the same as d. twice the NURSINGTB.COM Seidel's Guide to Physical Examination 9th Edition Ball Test Bank Downloaded by SMARTDOVE SMARTDOVE () lOMoARcPSD| NU RS IN GT B.CO M e. five times the ANS: D Lymphatic tissues are small compared to the total body size, but they are almost fully developed at birth. They grow fast and are about twice the adult size by 10 to 12 years of age. TOP: Discipline: Physiology MSC: Organ System: Hematopoietic/Lymphoid 5. Which organ(s) complete(s) physical development more quickly than any other body part? a. Brain b. Kidneys c. Heart d. Lungs e. Lymphoid tissue ANS: A Along with the skull, eyes, and ears, the brain completes development more quickly than any other part of the body; its most rapid growth occurs from conception to age 2 years. TOP: Discipline: Physiology MSC: Organ System: Nervous 6. During adolescence, the head size normally increases as a result of: a. sinus development. b. brain mass increase. c. evolution of lymphatic tissue. d. hypertrophy of glial cells. e. hypertrophy of myelin. ANS: A As the facial sinuses grow, the head size enlarges its surface area to accommodate this growth. TOP: Discipline: Physiology MSC: Organ System: General 7. Fifty percent of an individual’s ideal weight is gained during: a. pregnancy. b. preschool years. c. adolescence. d. early adulthood. e. older adulthood. ANS: C During adolescence, the trunk and legs grow the most, causing organs and the skeletal mass to double in size. During pregnancy, weight gain is accounted for by the growing fetus and pregnancy organs (placenta and uterus). In the preschool years, weight is gained at a steady rate, with fat tissue increasing slowly until about 7 years of age. In early adulthood, there is a reduction in size and weight. A decrease in weight for height and body mass index has been found with increasing age between 70 and 89 years of age. TOP: Discipline: Physiology MSC: Organ System: General 8. Sexual maturation begins earlier in girls with a higher: a. upper-to-lower segment ratio. NURSINGTB.COM Seidel's Guide to Physical Examination 9th E
