Q

What are the steps of fertilization?

A

Fusion of the spermatozoon

spermatozoon binds to glycoprotein on zona pellucida surrounding oocyte

spermatozoon releases enzymes to degrade the zona

spermatozoon and oocyte plasma membranes fuse

oocyte cancels membrane pot with Ca

male and female haploid pronuclei make contact and lose their nuclear membranes

off to mitosis

Q

What are the two forms of mesoderm?

A

mesenchyme

epitheliod

17
Q

What are mesenchyme cells?

A

bunches of stellate cells - motile - not good for communicating

18
Q

What are epithelioid cells?

A

mesoderm cells that are oraganized - they touch each other so they are good for communication

19
Q

What does the neural crest become?

A

pigment cells of skin

peripheral nervous system

adrenal medulla

mesenchyme - which then becomes meninges, bones, fascia, and teeth

20
Q

What does paraxial mesoderm become?

A

somites

21
Q

What are the 3 regions of somites?

A

schlerotome

dermatome

myotome

22
Q

What does the schlerotome give rise to ?

A

vertebrae, ribs, endochondral bones

23
Q

What does dermatome give rise to?

A

dermis of skin

24
Q

What does myotome give rise to?

A

skeletal muscles

25
Q

How do you get from a flat embryo to a cynlindrical tube?

A

1) Head process formation
2) Tail Formation
3) Lateral Body Folds

26
Q

what do the lateral body folds give rise to?

A

embryonic coelom

somatopleure

splanchnopleure
