Histology Flashcards
The study of microanatomy of cells, tissues and organs
Histology
Units of measurements in microscopy
Angstrom
Micrometer
Micron
The father of Microscopic Anatomy and Histology
Marcello Malphigi
He discovered the microscope
Leeuwen Hoek
It is the basic structural unit of life
Cell
Differences between prokaryotic and Eukaryotic
Prokaryotic- no true nucleus, found in bacteria, cell membrane not defined, Binary fission and contains one copy of each gene- Haploid
Eukaryotic- True nucleus, found in Animal, Plant, Fungi, and unicellular organisms, defined cell membrane, undergoes Meiosis and Mitosis
First growth phase of the cell
G1 Phase
Dna synthesis where TWO sister chromatids are produced
S- phase
Second growth phase of the cell
G2 Phase
preparation or resting phase for MITOSIS
Interphase
Majority of life cells are in what phase?
Interphase
Phase where in chromosome condense and become visible “PAIR UP”
Prophase
Phase where mitotic spindle apparatus forms at the opposite poles of the cell.
Prophase
Mitotic spindle is made up of?
MICROTUBULE
Chromosome checkpoint
Metaphase
Phase where chromosome align at the equatrial plate and held in place by microtubules.
Metaphase
Phase where sister chromatids and centromere separate and move toward the oppsite poles
Anaphase
phase when daughter chromosomes arrive at the poles and microtubules disappear.
Telophase
Phase where the last stage of Mitosis when there is Cleavage furrow
Cytokinesis
Chromosome with shorter arm
P- arm
Chromosome with longer arm
Q-arm
Pat of a cell that is made up of semi-permeable phospholipid bilayer
Cell membrane
Cell membrane is also known as
Plasma membrane / Cytoplasmic membrane
The major constituents of cell membrane
Lipid and Proteins
The major Non-Phospholipid constituent of cell membrane
Cholesterol
The fluid found inside the cell where organelles are suspended
Cytoplasm
These are tiny cellular structures that perform specific functions within a cell and are embedded within the cytoplasm
Organelle
A double membrane organelle containing the genetic information carried by DNA
Nucleus
Contains RNA for ribosomal synthesis (rRNA)
Nucleolus
a double membrane orhganelle that is the powerhouse of the cell
Mitochondira
ATP production in mitochondira is?
KREBS CYCLE
ATP becomes ADP via?
Oxidative phosphorylation
It is the lipid that participates in mitchondira electron transport.
Ubiquinone
Organelle that contain ribosome for protein synthesis
Rough (granular) endoplasmic reticulum
Rough ER is most abundant in what organ?
Thyroid gland
Organelle that has no ribosome but for lipid and glycogen synthesis also for DRUG DETOXIFICATION
Smooth ER
