BIOL 1300 Exam 6
| Question | Answer |
|---|---|
| The vitreous and aqueous humors are found in the | the eye |
| The primary cation in the interstitial fluid is | sodium |
| The concentration of electrolytes in body fluids is regulated by the actions of | hypothalamus, buffers, calcitonin |
| The most important osmoreceptors are located in the | hypothalamus |
| The activity of the thrist center will be increased if | blood osmolarity is increased |
| The most abundant anion in plasma membranes is | phosphate |
| Blood calcium levels are increased by | parathyroid hormone |
| A decrease in the rate and depth of breathing could theoretically alleviate | metabolic alkalosis |
| Symptoms of high plasma pH may include | muscle twitches |
| Addison disease is a disorder of the | adrenal cortex |
| The largest volume of water is excreted by the | urinary system |
| The term retroperitoneal means | behind the peritoneum |
| The outer portion of the kidney is called the | renal cortex |
| Which of the following best represents the path of a blood cell as it passes through the kidney? | glomerus, afferent arteriole, pertibular capillaries, renal vein |
| Which of the following structures is found in the renal medulla? | pertibular capillaries |
| The part of the nephron that drains in the nephron loop is the | proximal convoluted tubule |
| The juxtaglomerular apparatus consists of cells in the | distal convoluted tubule; afferent arteriole |
| An active process that moves substances from the blood into the nephron is | tubular secretion |
| Substances are reabsorbed from the distal convoluted tubule into the | peritubular capillaries |
| Antidiuretic hormone increases | water reabsorption in the collecting duct |
| Micturition is an action of the | urinary system |
| Based on your knowledge of word parts, nephrectomy is most likely the removal of the | kidney |
| Inflammation of the renal pelvis and kidney results in | pyelonephritis |
| The interstitial cells of the testes produce | testosterone |
| The ligaments holding the ovary in place include the | broad ligaments |
| The glans penis is formed by the | corpus spongiosum |
| The coiled tube on the testes that stores spermatozoa is the | epididymis |
| Name of a gland(s) that is found in women? | greater vestibular glands |
| The head of the spermatozoon contains large amounts of | DNA |
| An acrosome would be found in a | spermatozoon |
| The uterine proliferative phase occurs during | follicular phase |
| High levels of progesterone result in | decreased levels of leutinizing hormones |
| Increased activity of the interstitial cells results in | decreased leutinizing hormone secretion |
| Based on your knowledge of word parts, mastitis is | inflammation of the breast |
| Cryptorchidism is | a testes that remains in the abdomen |
| The normal chromosome number of the zygote is | 46 |
| The hormone produced by embryonic cells that maintains the corpus luteum is | (HCG) human coriotic gonadotropin |
| The umbilical cord contains | two arteries and one vein |
| An important factor in the initiation of labor is | increase n maternal prostaglandins |
| Labor can be artificially initiated by the administration of | oxytocin |
| Labor has officially begun when | regular uterine contractions begin |
| Parturition is officially complete when | bleeding is controlled |
| Pregnancy hormones that prepare the breast for lactation include | prolactin, progesterone, human coriotid mammosomatotropin |
| Colostrum is secreted by the | mammary glands |
| An example of a malignant tumor of placental tissue | choriocarcinoma |
| The units of hereditary are called | genes |
| Chromosomes contain | genes, DNA, alleles |
| A recessive gene | only alters the phenotype in homozygous individuals |
| An individual that is heterozygous for a completely dominant trait | will show the dominant phenotype |
| An example of genotype is | heterozygous alleles |
| Eye color is determined by three pairs of genes. Its mode of inheritance is best described as | multi-factorial |
| The ability of a particular gene to determine phenotype can be altered by | other genes, gender, environmental factors |
| What is true of multifactorial traits? | they're detremined by one or more gene pair |
| A chemical that causes a chromosome to break is called a(n) | mutagen |
| Duchenne muscular dystrophy results from a defect in the dystrophin gene and is detectable at birth. This disorder is best described as | congenital, hereditary, genetic |
