BSC 343 Exam 1 Questions And Answers
neurons -
correct answer ✅functional cells of the nervous system
glial cells -
correct answer ✅support cells (more numerous)
dendrite -
correct answer ✅input/translation
cell body -
correct answer ✅integration, nucleus (transcription), translation
(ribosomes), axon hillock (connects to axon)
axon -
correct answer ✅conduction, initial segment
axon hillock -
correct answer ✅Cone shaped region of an axon where it joins the
cell body.
axon initial segment -
correct answer ✅the segment of the axon where action potentials
are generated - located immediately adjacent to the axon hillock
,BSC 343 Exam 1 Questions And Answers
astrocytes -
correct answer ✅elaborate processes; participate in
uptake/metabolism of neurotransmitter
oligodendrocytes -
correct answer ✅restricted to CNS; support/insulation of axon
schwann cells -
correct answer ✅restricted to peripheral axon; produce myelin
sheath
microglia cells -
correct answer ✅immune cell; removes cellular debris
stem cells -
correct answer ✅proliferate and make other differentiated cell
types
glial stem cells -
correct answer ✅become differentiated glia and neurons
, BSC 343 Exam 1 Questions And Answers
oligodendrocyte precursors -
correct answer ✅scattered through white matter (myelin); become
oligodendroglial cells/astrocytes
measurement of electrical activity -
correct answer ✅measuring membrane potentials and smaller
graded potentials
microscopic measurement -
correct answer ✅fluorescent microscope with use of calcium
voltage sensitive dye
knock-ins/knock-outs -
correct answer ✅introduce gene in embryonic stem cells
Cre/lox system -
correct answer ✅introduce Cre recombinase + loxP binding sites;
expression of recombinase excises gene of interest surrounded by
loxP binding sites
CRISPR -
correct answer ✅RNA guide sequence (gRNA) binds endonuclease
(Cas9) + cuts DNA. repair disables genes or inserts new gene
