2. Cellular Division Flashcards
Phase when cells stop dividing
Examples
G0 phase
Cardiac cells and neurons
3 phases of interphase
G1
S
G2
Phase: chromosome duplication
Synthesis phase
Division of SOMATIC cells
Mitosis
Division of SEX cells
Meiosis
Chromatin condenses
Prophase
Align at the equator
Metaphase
Chromosomes split
Anaphase
Chromatid goes back to chromatin
Cleavage furrow forms
Telophase
Steps 1-4 or PMAT is also called
Karyokinesis (nucleus/to split)
Part of mitosis where cytokinesis happens
Telophase
Cytoplasm divides into two
Cytokinesis
What 2 things happen in Meiosis 1 prophase 1
Synapsis
Recombination
Phenomenon wherein HOMOLOGOUS chr PAIR during meiosis
Synapsis
Sharing of DNA of 2 homo chromo aka CROSSING OVER or CHIASTMATA FORMATION
Recombination
End product of meiosis 1
Sperm - 2 diploid
Egg - 1 diploid & 1 polar body
End product of meiosis 2
Sperm- 4 haploid
Egg - 1 haploid & 3 polar bodies
Only blood supply of heart
L and R coronary artery
Decreased blood supply
Ischemia
Loss of blood supply due to obstruction
Infarction
Common cause of infarction
Obstruction of smaller vessels
Other term for myocardial infarction
Heart attack
Common cause of death of MI
Arrthymia or irreg heartbeat
Most common organ assoc with infarction
Heart
Brain infarction
Cerebrovascular accident or stroke
Least involved organ in infarction
Liver
Most common artery involved in stroke
Lenticulostriate artery (branch of middle cerebral artery)
Initial response of heart to hemorrhage
Tachycardia : Inc in fxn to help brain
Total body fluid volume
60% of weight
2 types of blood fluid volume and %
Intracellular fluid - 40%
Extracellular - 20%
Blood volume = _% of body weight
8%
If blood volume (8%) not maintained it will result to loss of blood flow or ____
Hypovolemic shock or hemorrhagic shock
Longest phase of cell division
Interphase
Male with bar body
Klinefelter Syndrome
44XX
Features:
Klinefelter
Glynecomastia
Micropenis
Taurodontism = Bull’s teeth
Bull’s eye lesion (2 disease)
- Erythema Multiforme
2. Lyme’s Disease
Loss of blood flow
=TACHYCARDIA
Hemorrhagic shock
Obstruction in coronary artery
MI
