Can you name the Embryology Unit Key Words? by RzWelshy

Lecture 1
Penetration of the egg by more than one sperm
Membrane forming around the egg cell membrane
Thick layer to protect the egg cell
Specialised vesicles in the plasma membrane
A small organelle in sperm containing enzymes
Process of sperm releasing the enzymes
Part of sperm that penetrates the egg
Approximate time for plasma membrane to depolarise, preventing other fertilisation
Water entering the peri-vetelline space creates this membrane
Time until transcription/translation occur post fertilisation
Time until first cell division, post fertilisation
Fertilised egg divides into nucleated (x) without changing size
Name for embryo at 32 cell stage
Hollow cell ball structure
The hollow center of the ball
Cleaved nuclei held in the same cytoplasm (only in insects)
Pole of the egg where the yolk gathers
Pole of the egg where the embryo is
Developmental stage where body plan is determined
Movement of cells from the outside to the interior of the hollow ball
Two layered, hollow embryo
Hollow space in this embryo
Point of internal movement [point of (Answer 20)]
Thin embryo of birds
Hollow ball of about 100 cells (in mammals)
The embryos contribution to the placenta
Organisms where the (answer 23) forms the mouth
Organisms where the (answer 23) forms the anus

Lecture 2
Process of layers forming rudimentary organs
Formation of the central nervous system
Flexible rod down the length of the organism, found in all chordates (first feature to form)
Forms the nervous system (second feature to form)
Formed by the closing of the Neural groove
Blocks of the mesoderm form into (x)
Amniote embryos are surrounded by these during development
Membrane formed by fusion of chorion and allantois
Formed from part of the chorion, provides nutrients to some mammal embryos
Formed from the allantois, provides gas exchange for fetal blood
Actin filaments and microtubules inside cells
Process responsible for elongating tissues
A mixture of secreted glycoproteins outside the plasma membrane
Map of which part of the embryo develops into what
Totipotent cells found in embryos

Lecture 3
A substance that determines the fate of the cells that inherit it
The influence of the environment around the cell for development
The end result of cytoplasmic determinants
Pattern of cleavage in insects
Cytoplasmic determinants present in an unfertilised egg
Example of (answer 48) found in Drosophila, controls head formation
A gene that binds to DNA and affects transcription of other genes
Genes that only affect every other segment
Genes that specify anterior and posterior organisation
Genes that control placement of body parts
A DNA binding region which controls the transcription of other genes
