Behavioral Neuroscience Cps (1,2,3,4) Flashcards
What do neurons do?
detect changes and communicate those changes to other cells, & command the bodys response
What do Glia do?
insulate, support, and nourish neurons
What does the Nissle Stain show?
nuclei and surrounding
What does the gogli stain show? and how does it work?
cell body and neurites, using silver chromate
What kind of stains did golgi and Cajal use?
Gogli stain
what theory did golgi beleive?
network theory (reticulum) : neurties are fused together, individual cellas are not uniquely different.
What theory did Cajal beleive in?
Neuron Doctrine (cell theory): cells are not continuos and they communicate by contact not continuity.
Which theory is correct and who held this beleif?
Neuron Doctrine (Cell theory), Cajal
Cytosol
Watery like substance inside the cell with ions.
Cytoplasm
Nucleus
contains chromosomes, dna, then genes.
Genes
Segments used to create products for the cell
Protiens
proteins are created when mRNA goes through a ribosome or a rough er
mRNA
RNA is the Reverse copy or DNA, RNA then gets processed and cut down into a mRNA transcript
the process of Gene transcription
When we have to ship information about how to make a protein outside the cell nuclease, we send a photocopy of the gene.
the process of translation
Translation happens after we’ve made mRNA, we slap ribosomes onto mRNA and this creates proteins. JOB WELL DONE
Knockout Mice
One gene has been deleted or “knocked out”
Transgenic mice
Genes have been introduced and over expressed
what can knockout mice and transgenic mice be used to study?
ways to change organisms by design with gene mutations or insertions
Rough Endoplasmic Reticulum
inside the cell, conducts proteins sythesis on rybosones
RIbosomes
main runction is protein snythesis
Mitocondrion
Power house of the cell, takes provic acid and Creates ATP
the membrane and its function
- encloses cells, prevents various substances in the extracelluar fluid from entering cell
- filled with proteins
the axon
coomunicates
axon hillock
closest part of axon to cell
axon branches
axon terminal
where the axon ends (button) where communication happens from one cell to another
synapse
the coming together of two cells.
when a cell is providing innervation, what is it doing?
Space between pre- and post-synpatic components is called
cynaptic cleft
transfer of information is called
action potential
what are synaptic vesicles and nuerotransmitters
synaptic vesicles are filled with neurotransmitters, they fuse with pre-synaptic membranes
neurotransmitter
neurotransmitters release a chemical signaled from synaptic vesicles
what does the word dendrite come from
dendron greek for (tree)
dendrite
the listeners part of neurites
?whats a dendritic tree?
the dendrites of a single neuron
what is the similarity between dendrites and antennae?
recepters(define) how are they related to neurotransmitters?
dendritic spines (what do they look like? try to use your own words
unipolar (define and draw example; label why its unipolar)
bipolar (define and draw example; label why its bipolar)
multipolar (define and draw example; label why its multipolar)
most neurons are…
stellate cells are … shaped (draw example)
pyramid cells are .. shaped (draw example)
what is meant by (spiny/aspinous)
Primary sensory neurons (define)
motor neurons (define)
interneurons (define)
most neurons are…
astrocytes (what is their role)
mylinating glia
what are different types of mylinating glia (define, and differences)
