What is ampulla of fallopian tube?
This is the site of fertilization in the uterus
|
What are osmotic and hydrostatic driving forces ?
These are the two major driving forces for water.
|
DF = (-83) - (-83) = 0
no net movement.
What is the DF of a cell if Vm is -83mV and the ion in question is potassium?
DF = Vm -Eion |
What is neoplasm?
This is used t describe "new growth" or an abnormal mass of cells
|
What is atrophy?
This describes a decrease in the size of cells
|
|
What is syncytiotrophoblast?
This outer layer of cells derives from the trophoblast and secretes HCG and erodes the lining of the uterine wall to allow burrowing of the blastocyst.
|
What is Osmolarity?
This the total of all concentrations in solution
|
DF = (-50) - (-83) = +33
outward movement = efflux .
What is the DF of a cell if Vm is -50mV and the ion in question is potassium?
DF = Vm -Eion |
What is metastasis?
The spread of tumor cells throughout the body.
|
What is metaplasia?
This describes a complete change in cell differentiation
|
|
What is epiblast?
The endoderm, mesoderm and ectoderm all derive from this layer
|
What is tonicity ?
the concentration of only osmotically active particles
|
DF = (-95) - (-83) = -12
inward movement = influx.
What is the DF of a cell if Vm is -95mV and the ion in question is potassium?
DF = Vm -Eion |
What is necrosis?
Cell swelling, loss of plasma membrane integrity, release of cell contents , surrounding tissue damage and inflammation is described by this word
|
What are cloudy swelling, hydrophobic degeneration and fatty change?
These three phases occur in cells as the early response to injury
|
|
What is corona radiata?
This is the area on the oocyte that first comes into contact with the sperm during capacitation?
|
What are glucose, urea, and glycerol (GUG)?
These solutes are classified as penetrating and can enter the cell without moving wate.
|
DF = (-50) - (+60) = -110
inward movement = influx
What is the DF of a cell if Vm is -50mV and the ion in question is sodium?
DF = Vm -Eion |
What is apoptosis?
This process can be done in two pathways.
|
What is carcinoma in situ?
Epithelial tissue that shows features of carcinoma without a breach of basement membrane and show increased mitotic activity
|
|
What is ectoderm?
Neural Crest Cells derive from this layer
|
What is Hyperosmotic?
how do you classify a solution that has greater osmotic pressure than the cell.
|
DF = (-50) - (-66) = +16
inward movement = influx
What is the DF of a cell if Vm is -50mV and the ion in question is chloride?
DF = Vm -Eion |
What is Bax?
This pro-apoptotic protein makes the mitochondria more permeable and causes cytochrome C to be released
|
What is dysplasia
Failure of differentiation and maturation, large nuclei with dark staining chromatin and increased risk of neoplasia can be used to describe this word
