lecture 1 Flashcards
proliferation
getting larger; cell division
course objectives
cell proliferation, specialization, interaction, movement
cell proliferation
going from small to large
cell specialization
embryonic primordial cells that are multipotent
what is multipotent
can have one of many diff fates
cell interaction
how cells interact w/ each other and exert forces on each other to make dramatic changes in shape
cell movement
cells aren’t static; they move from point A to point B
sebaceous glands
cells that secrete oil
where does the oil travel
up the hair
what is morphogenesis
tissue shaping
proliferation
fertilized egg to blastula
gastrulation
blastula to gastrula
what happens as it goes from blastula to gastrula
tissue shaping
step one of epithelial cells
theres a sheet of epithelial cells; invagination caused by organized tightening along adhesion belts in selected regions
what is second step
epithelial tube pinches off from overlying sheet of cellsw
