Integrating Cells Into Tissues Flashcards
1
Q
Why do cells require energy?
A
- separation of DNA
- replication of DNA
- production of RNA & proteins
- signal propagation
2
Q
Plasma Membrane
A
- selective movement
- dynamic structure – communication
- hydrophobic barrier
3
Q
What surrounds a zygote? What follows a zygote?
A
- zona pellucida
- morula
4
Q
Components of the cell during development and their locations?
A
- embryo-blasts (packed near top)
- blastocyst cavity (space within cell)
- trophoblasts (line the inside of cell)
5
Q
Components of the cell post-implantation and their locations?
A
- amniotic cavity (top of cell)
- epiblasts – embryo (packed near top)
- hypoblasts (line epiblasts)
- primitive streak (cleft for cells to move in + caudal end)
6
Q
What are the 3 germ layers and where are they found?
A
Ectoderm - nervous system
Mesoderm - muscle, circulatory system
Endoderm - digestive tract, liver, respiratory tract
7
Q
What are the 4 Tissue Types?
A
Nervous Tissue
Musular Tissue (skeletal, smooth, cardiac)
Epithelial Tissue
Connective Tissue (adipose - energy + protect / collagen - bone + cartilage)
