nervous system contains 2 ? |
Pheripheral nervous system (pns) central nervous system(cns) |
|
cns |
brain and spinal cord |
|
pns |
cranial and spinal nerves that extend beyond cns
|
|
autonomic |
(PNS)
|
|
sensory-somatic nervous sytem |
(PNS)
|
|
gangila |
collections of nerve cell bodies |
|
dendrites |
they receive stimuli from internal & external environment and bring back to nerouons for interpetation |
|
phagocytosis |
engulfing of pathogens by white blood cells |
|
perforins |
natural killer cells produce this -pore forming proteins that target virus and cancer cells -causes cells to lyse |
|
interferons |
body's response to viral infection -prevent cells from replication after 7-10 days -activate nk cells |
|
chemotaxis |
leukocytes respond to damaged body tissue -cytokines-chemical messengers that are released by damaged cells play a roll |
|
diapedesis |
process of WBC squeezing through capillaries slits in response to cytokines (followed by cellular adhesion molecules guiding white blood cells to site of damage) |
|
active immunity |
-vaccine -after vaccine body stimulates actual infection by pathogen stimulating body to produce antibodies for future protection |
|
passive immunity |
body does not make own antibodies -receives them directly (nursing) |
|
cell medicated immunity |
t cells (lymphocyte that triggers the action of other lymphocytes) are primarily responsible for recognizing nonself cells |
|
natural selection |
some individuals of a species are better able to survive in their enviornment and able to reproduce others |
|
alleles |
every gene exists in different forms |
|
adaption |
mutations in alleles allowing better survival (natural selection produces it) adaption is end result |
|
microtubules |
cellular tracks that, during mitosis, form the miotic spindle. spindle helps organize and segregate the chromosomes during cell division. |
|
centrosomes |
microtubules-organizing centers that help to form and organize the mitotic spindle during mitosis |
|
cell differention |
produces more specilized cell can happen as adult or embryo ex:stem cell |
|
cell replication |
g1 s g2 |
|
g1 |
|
|
s (synthesis) |
|
|
g2 |
continued protein synthesis and cell growth preparation for cell division |
|

|
|
telophase 1 |
|
|
haploid |
single set of chromosomes |
|
diploid |
cells that contain two sets of chromosomes |
|
prophase 2 |
|
|
metaphase 2 |
sister chromtaids align at new metaphase plate
|
|
anaphase 2 |
sister chromatids separate again |
|
telophase 2 |
4 haploid cells result after cytokinesis |
|
sister chromatids |
two identical copies if dna |
|
meoisis and mitosis occur? |
|
|
photosynethis |
carbon dioxide + water + sunlight= Glucose + Oxygen (atp) atp is fuel for cell from co2 and water |
|
cellular respiration |
glucose+oxygen=carbon dioxide+water+energy
|
|
dna repair process |
|
|
germ cells |
reproductive cells that pass genetic info on to offspring |
|

ROYGBIV |
|
METRIC SYSTEM TO MEASURE WORK |
joules or calories (smaller) kilojoules or kilocalories (1000) |
|
KE |
energy of motion KE=1/2mv(squared) |
|
PE |
stored energy PE=mgh |
|
catalysts |
control rate of chemical reaction, or reactions in which atoms react to come stable
|
|
reaction rates |
depend on frequency of contact of reactants with the catalysts (may be artificially accomplished by increasing substrate (molecular surface acted upon by enzyme) |
|
catalysts 4 step process |
(C)catalyst (Z)product (x&y) reactants catalysts present with product to repeat |
|

up an down same number of valence electrons (outer shell electrons |
|
periodic table-row/ period |
left to right same number of shells |
|
ionization energy |
energy required to completley remove an electron from gaseous atom or ion increase moving left to right increase moving bottom to top |
|
atomic radius |
decreases left to right decreases bottom to top |
|
electronegativity |
measure of atoms attraction on electrons in a chemical bond greater electronegativity, greater attraction for bonding elements that have low ionizaton have low electronegativity electronegativity decreases as atomic number increases |
|
chemical bonding |
chemical merging of atoms due to their electron arrangment, determined by location on a given row bonding rules:transition between metals and non metals is also given to exist from L to R within each row. |
