EMBRYOLOGY Flashcards
WHAT ARE THE 6 CHALLENGES OF EMBRYONIC DEVELOPMENT
CRANIOCAUDAL AXIS
ANT POST AXIS
MED LAT AXIS
LIMB CREATION
SYM IN ASYM OUT
ORGANOGENESIS
WHAT DOES GAMETOGENESIS MEAN
THE DEVELOPMEN AND PRODUCTION OF THE MALE AND FEMALE GERM CELL
WHAT IS OVULATION
THE DEVELOPMENT AND RELEASE OF AN OVUM
WHAT IS FERTILISATION
THE JOINING OF TWO GAMETES
WHAT IS EMBRYOLOGY
TH STUDY OF ORIGIN, GROWTH, DEVELOPMENT AND FUNCTION OF AN ORGANISM
WHAT ARE THE THREE PERIODS OF DEVELOPMENT
PREEMBRYONIC, EMBRYONIC, FETAL
WHAT IS THE PRE-EMBRYONIC PHASE
THE PERIOD BETWEEN FERTILISATION AND IMPLANTATION
WHAT IS THE EMBRYONIC PHASE
IMPLANTATION TO WEEK 8`
WHAT IS THE FETAL PHASE
WEEK 9 TO BIRTH
WHAT IS INVOLVED IN FERTILISATION
FUSION OF SPERM AND OVUM TO MAKE A ZYGOTE
WHAT IS THE TIMELINE OF FERTILISATION
WITHIN 24 HOURS OF OVULATION
WHAT IS CLEAVAGE
A SERIES OF RAPID CELL DIVISIONS THAT FORM THE MORULA
WHAT IS THE TIMELINE FO A BLASTOCYST
4-5 DAYS
WHAT IS A BLASTOCYST
THE MORULA DEVELOPS A FLUID FILLED CAVITY TURNING IT INTO A HOLLOW BALL
WHAT IS THE TIMELINE OF IMPLANTATION
DAY 7
WHAT IS IMPLANTATION
THE BLASTOCYST SECRETES STUCKY PROTEINS AND ATTACHES ITSELF TO THE UTERINE WALL
WHAT IS THE TIMELINE OF THE BILAMINAR EMBRYO
DAY 14/ WEEK 2
WHAT IS THE BILAMINAR EMBRYO
THE BASTOCYST SPLITS INTO TWO LAYERS THE EPI AND HYPO BLAST
WHAT DOES THE EPIBLAST BECOME
TEH EMBRYEO
WHAT DOES THE HYPOBLAST BECOME
SUPPORTING TISSUES (PLACENTA)
WHAT IS THE TIMELINE OF GASTRULATION
DAY 15 WEEK 3
WHAT IS GASTRULATION
THE BILAMINAR EMBRYO IS TRANSFORMED INTO A TRILAMINAR EMBRYO
WHAT IS THE TIMELINE OF EMBRYONIC FOLDING
START OF WEEK 4
WHAT IS EMBRYONIC FOLDING
THE TRILAMINAR DISC FOLDS CYLINDRICALLY AND THEN INTO A CRESCENT SHAPE
WHAT ARE THE THREE LAYERS OF THE TRILAMINAR DISC
ECTODERM , MESODERM, AND ENDODERM
WHAT DOES THE ECTODERM BECOME
CNS, EPIDERMIS HAIR SKIN AND NAILS
WHAT DOES THE MESODERM BECOME
BODY TISSUES - MUSCLES, BONE AND CT , BLOODVESSELS AND DERMIS
WHAT DOES THE ENDODERM BECOME
EIPTHELIAL LINING OF GI TRACT, RESPIRATORY AND URINARY SYSTEMS
WHAT IS THE TIMELINE OF NEURALATION
3-4 WEEKS
WHAT IS NEURALATION
FORMATION OF THE PRIMITIVE NERVOUS SYSTEM - THE NEURAL TUBE AND CREST WHICH TURNS INTO THE SPINAL CORD AND BRAIN
WHAT ARE SOMITES
CELLS FORMED IN THE MESODERM THAT FORM DERTOMES, MYOTOMES, AND SCLERTOMES
