CELL NUCLEUS Flashcards
Occupies the center of the cell and the largest structure
- contains genetic information
- dna replication and rna transcription and processing
Cell nucleus
The removal of cell nucleus leads to cell death, true or false
True
It contains dna and nuclear transm responsible for nuclear basophilia
Chromatin
Small area with in the nucleus that contains dna rna
Nucleolus
Surrounds the cell nucleus separating it from the cytoplasm
Nuclear envelope or membrane
Nuclear contents like the chromatin and nucleolus
Nucleoplasm
What do you call to liver cells
Hepatocytes
It is the salary renewal that sells that no longer divide
Static
Static sample
Cns, skeletal and cardiac muscles
Says that divide episodically and slowly to maintain normal tissue or organ structure
Stable
Stable samples
Fibroblast
connective tissue
red blood cells
Example of slowly renewing cells
Smooth muscle cell hollow organs fiber blast
epithelial cells GIT
Example of rapidly rewing cells
Blood cells
epithelial cells of skin
epithel cells of git
Represents a self regulated sequence of events that control cell growth and cell division
Cell cycle
Equal partitioning of replicated chromosomes and their genes into two identical groups
Mitosis
Four phases of mitosis
Prophase
metaphase
anaphase
telophase
Increase in the number of cells in a organ or tissue
Hyperplasia
Accidental cell death
pathologic process
Irreversible
rapid cell swelling
Necrosis
Program cell death
Apoptosis
Functions of apoptosis
Deny fragmentation
decrease of cell volume
