MIDTERM 1- VERSION B i i i
1. Know icomponents iof ithe ilipid ibi-layer
o The ibasic istructural iframework iof ithe iplasma imembrane iis ithe ilipid ibilayer, itwo
iback-to-back i layers i made iup iof ithree itypes iof i lipid i molecules—phospholipids,
icholesterol, iand iglycolipids
o The ibilayer iarrangement ioccurs ibecause ithe ilipids iare iamphipathic imolecules, iwhich
imeans ithat ithey i have iboth ipolar iand i nonpolar iparts.
2. Bonds ibetween iwater imolecules- iwhat itype iof ibond iis iit?
o Polar icovalent/hydrogen ibond
3. Facilitated idiffusion iand iwhat irole idoes icarrier iprotein iplay
o Carrier iproteins itransport isubstances iacross imembranes iby ichanging ishape
4. Know iTranscytosis
o Active iprocess iof imoving isubstances iacross ia icell iusing ivesicles, imost ioften iacross
iendothelial icells i lining i blood ivessels
5. Is ia isynovial imembrane iconsidered ian iepithelial imembrane?
o No, iit iis inot
6. Know iwhat irole itriglycerides iand icholesterol iplays iin ibody
o Triglycerides: iprotection, iinsulation, ienergy istorage
o Cholesterol: iin ibile isalts, ivit iD iand isteroid ihormones, iimportant ifor isteroid isynthesis
7. Know ilocation iof ithe iNail iBed i(hyponychium)
8. Which ilayer iof ithe iepithelium iis inot ipresent iin iThick iskin?
o Lucidum iis inot iin ithin iskin
o Thick idoes inot ihave ithin icorneum
9. Properties iof iEnzymes

, 10. What iis inot ia icommon icharacteristic iof iepithelium?
o Epithelium iare icharacterized iby ithe iarrangement iof icells iin ilayers iand itheir ishapes
o Characteristics: icellularity, ipolarity, iattachment, ivascularity iand iregeneration
11. Choose iexample iof ia ipositive ifeedback isystem
o Birth, iovulation, iblood iclotting, idigestion
12. Wound ihealing- idoes iit iresult iin iFibrosis?
o Fibrosis iis ithe iformation iof iscar itissue iat ian iinjury ibut iimpairs ioriginal ifunction
13. What ilines ithe iMedullary iCavity?
o endosteum
14. What iorganelle imetabolizes iETOH iin ithe iliver?
o Smooth iER
15. Know iwhich iepithelium ilines ithe iheart, ilymph ivessels iand iarteries
o Simple isquamous iepithelium, iendothelium
16. Understand iMitosis iand ithe iphase iwhere ichromosomes iare ivisible iunder imicroscope
o prophase
17. Review iepithelial itissues
o 2 itypes
▪ Covering& ilining iepithelium ifor ithe iouter icover iof iskin, isome iorgans iand ithe
iinner i lining iof ivessels, iducts iand icavities
▪ Glandular iepithelium imakes iup ithe isecreting iportion iof iglands
18. Location iof iForamen iMagnum iand iwhich ibone iof ithe iskull iit iis ilocated iin
o The iforamen imagnum iis ithe iinferior ipart iof ithe ioccipital ibone
