Embryology Part 1 Flashcards
Which vital property of a cell is directly associated with actin filaments?
Contractility
Which cells have an abundance in actin filaments?
Muscle cells
What is the biological science branch that focuses on the study of the individual in the prenatal stage?
Embryology
What begins with gametogenesis and ends at birth?
Embryology
What are male cells called?
Spermatozoa
What are female cells called?
Oocytes
What is the result of oocyte + spermatozoa?
Zygote
Where is spermatozoids deposited in the female?
Vagina or uterus
What protects seminal secretions?
pH
What is the loss of surface cholesterol and glycoproteins?
Spermatozoa capacitation
During capacitation, what does the acrosome membrane fuse with?
Spermatozoon
What is made of golgi’s apparatus and enzymes?
Acrosome
What part of the oocyte do spermatozoon break through?
Corona radiata
What part of the oocyte do spermatozoon penetrate?
Zona pellucida
Where is the genomic material from spermatozoon released into in the oocyte?
Cytosol
Which meiosis, 1 or 2, does oocyte complete?
Meiosis 2
Fusion of pronuclei=
Zygote
Which process beings via mitosis?
Growth
In bird, does the female or male determine the sex of the offspring?
Female
During which phase does:
Zygote divides into blastomeres
Blasteromeres form a sphere- morula
Morula differentiates into- trophoblast and embryoblast
Morula migrates to uterine body- blastocyst
Blastocyst= END
Segmentation/Cleavage
During which phase does this happen:
Embryoblasts goes from a collection of cells to 3 tissue types- ectoderm, endoderm, mesoderm
Gastrulation
Which -derm, of gastrulation has the following:
Primitive node and groove
Notochord = END
Ectoderm
