CHAP. 27
| Question | Answer |
|---|---|
| THE FERILIZED OVUM | ZYGOTE |
| CELLS THAT SECRETE hCG | TROPHOBLASTS |
| A ZYGOTE-MAKING EVENT | FERTILIZATION |
| THE SITE WHERE BABY BREATHES, EATS, AND EXCRETES | PLACENTA |
| BABY'S LIFELINE; CONTAINS THE UMBILICAL BLOOD VESSELS | UMBILICAL CORD |
| BABY'S NAME AT AGE 3 TO 8 WEEKS AFTER CONCEPTION | EMBRYO |
| PROCESS WHEREBY THE BLASTOCYST BABY-TO-BE BURROWS INTO THE ENDOMETRIUM | IMPLANTATION |
| THE BIRTH PROCESS | PARTURITION |
| ENDODERM, MESODERM, AND ECTODERM | PRIMARY GERM LAYERS |
| BABY'S NAME FROM 9 WEEKS TO BIRTH | FETUS |
| HORMONE THAT STIMULATES THE MAMMARY GLANDS TO MAKE MILK | PROLACTIN |
| POSTERIOR PITUITARY HORMONE INVOLVED IN THE MILK LET-DOWN REFLEX | OXYTOCIN |
| HORMONE THAT SUSTAINS THE CORPUS LUTEUM | hCG |
| HORMONE THAT STIMULATES THE CONTRACTION OF THE MYOMETRIUM | OXYTOCIN |
| SECTETION OF THIS HORMONE CONTINUES AT A HIGH LEVEL FOR ABOUT 2 MONTHS, THEN STEADILY DECLINES AS THE PLACENTA TAKES OVER | hCG |
| HORMONE THAT STIMULATES Na= REABSORPTION AND EXPANDS BLOOD VOLUME DURING PREGNANCY | ALDOSTERONE |
| SEGMENTS OF A DNA STRAND THAT CARRY THE CODE FOR A SPECIFIC TRAIT SUCH AS EYE COLOR | GENES |
| TWENTY-TWO PAIRS (NUMBERED 1-22) OF CHROMOSOMES | AUTOSOMES |
| X AND Y CHROMOSOMES | SEX CHROMOSOMES |
| ANY TRAIT THAT IS CARRIED ON AN X OR Y CHROMOSOME | SEX-LINKED TRAIT |
| A CHANGE IN THE GENETIC CODE THAT MAY EXPRESS ITSELF AS A CHANGE IN A PARTICULAR TRAIT | MUTATION |
| A UTERINE EVENT ACHIEVED BY THE BLASTOCYST | IMPLANTATION |
| WHAT DOES HUMAN CHORIONIC GONADOTROPIN (hCG) MAINTAIN? | CORPUS LUTEUM |
| WHAT DOES TROPHOBLASTIC CELLS ASSIST WITH? | IMPLANTATION |
| REFERS TO THE ADORABLE PREEMBRYONIC CLUSTER OF CELLS | MORULA |
| THE SITE AT WHICH BABY-TO-BE BREATHES, VERY VASCULAR, AND REPLACES THE GLANDULAR SECRETION OF THE CORPUS LUTEUM? | THE PLACENTA |
| PLACE WHERE FERILIZATION OCCURS | FALLOPIAN TUBE |
| CLASSIFICATION OF FSH AND LH | GONADOTROPINS |
| MINERALOCORTICOID THAT EXPAND MATERNAL BLOOD VOLUME | ALDOSTERONE |
| TIGHTLY COILED STRANDS OF DNA; THE HUMAN NUMBERIS 46 | CHROMOSOMES |
| THE ARRANGEMENT OF CHROMOSOMES BY SIZE AND SHAPE; GENETIC ART | KARYOTYPE |
| THE FAILURE OF CHROMOSOMES TO SEPARATE DURING MEIOSIS, THEREBY CAUSING THE OVA OR SPERM TO HAVE TOO MANY CHROMOSOMES | NONDISJUNCTION |
| NUCLEOTIDE THAT CARRIES THE GENETIC CODE IN ITS BASE-SEQUENCING | DNA |
| A SPONTANEOUS CHANGE IN THE GENETIC CODE; EFFECTS MAY BE MINIMAL OR LIFE-THREATENING | MUTATION |
| WHAT HAPPENS FIRST? | ZYGOTE |
| A CREAM CHEESE LIKE SUBSTNCE THAT COVERS THE FETUS, PROTECTS THE SKIN OF THE FETUS FROM THE AMNIOTIC FLUID, AND IS SECTETED BY BABY'S SEBACEOUS GLANDS | VERNIX CASEOSA |
| REFERS TO MILK PRODUCTION BY THE MAMMARY GLANDS | LACTATION |
| THE NAME OF THE FINE DOWNY HAIR THAT COVERS THE FETUS | LANUGO |
| THIS YELLOWISH WATERY FLUID IS SECTETED B THE MAMMARY GLANDS IMMEDIATELY AFTER DELIVERY; BABY FEEDS ON THIS UNTIL THE MOTHER'S MILK COMES IN | COLOSTRUM |
| THIS HORMONE IS SECRETED BY THE TROPHOBLASTIC CELLS DURING IMPLANTATION AND HELPS TO PRESERVE THE CORPUS LUTEUM | hCG |
| IN ADDITION TO ACTING AN AN EXCHANGE SITE BETWEEN THE MOTHER AND FETUS, THE PLACENTA ALSO SECRETES | ESTROGEN AND PROGESTERONE |
| OCCURS WITHIN THE UTERUS | IMPLANTATION |
| A FERILIZED OVUM IS CALLED | A ZYGOTE |
| ANOTHER NAME FOR A TUBAL PREGNANCY IS CALLED? | ECTOPIC |
| REFERS TO THE SHAPING OF CELL CLUSTERS | MORPHOGENESIS |
| LITERALLY MEANS "SWIFT BIRTH" AND CAUSES MYOMETRIAL CONTRACTIONS | OXYTOCIN |
| IMPLANTS IN THE UTERUS | BLASTOCYST |
| A MOTHER-TO-BE INFECTED WIT THE RUBELLA VIRUS GIVES BIRTH TO A CHILD WITH MULITPLE BIRTH DEFECTS. A DESCRIPTIVE WORD FOR THE DEFECTS IS... | CONGENITAL |
| ASSOCIATED WITH ORGANOGENESIS IS IN WHICH PERIOD? | EMBRYONIC PERIOD |
| A CHILD WITH AN X AND Y CHROMOSOME IS | MALE |
