3.4 - Lab - BM Embryology Flashcards
1
Q
Mesenchyme
A
embryonic connective tissue
2
Q
Amniotic sac
A
outer space surrounding embryo
3
Q
neural tube
A
forms future ventricular system of the brain + spinal cord
4
Q
Basement membrane in embryo
A
sub-microscopic structure which separates he sheet of differentiated epithelial cells lining the space from the underlying, undifferentiated connective tissue
5
Q
integument
A
the future skin
6
Q
external membrane
A
the limiting structure around peripheral nerves that is identical in structure to the basement membrane (but is not basal to anything)
7
Q
endothelium of embryo
A
- always squamous shape
- vascular epithelium
- endothelial layer (between lumen and basement membrane) is always one cell thick
8
Q
pericardial sac of embryo
A
- space containing the heart and truncus arteriosus
- epithelium lining it is a simple squamous epithelium
