Question o1
Which olayer oof othe oskin ois ocomposed oof odense oirregular oconnective otissue oand
contains ocollagen oand oelastic ofibers?
o
A) oEpidermis
B) oDermis
C) oHypodermis
D) oStratum obasale
Correct oAnswer: oB) oDermis
Rationale: oThe odermis ois othe odeeper olayer oof othe oskin, ocomposed oof odense oirregular
connective otissue ocontaining ocollagen o(strength) oand oelastic o(flexibility) ofibers. oIt
o
also ocontains oblood ovessels, onerves, oglands, oand ohair ofollicles o.
o
Question o2
Which oof othe ofollowing ois oa ofunction oof othe ostratum ogranulosum?
A) oCell odivision
B) oKeratin oproduction oand owaterproofing
C) oMelanin osynthesis
D) oSensation
Correct oAnswer: oB) oKeratin oproduction oand owaterproofing
Rationale: oThe ostratum ogranulosum ocontains ogranules oof okeratohyalin oand olamellar
bodies. oKeratohyalin ohelps oform okeratin, oand olamellar obodies orelease olipids othat
o
waterproof othe oskin. oThis olayer ois owhere okeratinization obegins o.

, Question o3
What ois othe oprimary ofunction oof othe oarrector opili omuscle?
A) oTo oproduce osebum
B) oTo ocause ogoosebumps o(piloerection)
C) oTo oregulate obody otemperature othrough osweating
D) oTo oanchor othe ohair ofollicle oto othe odermis
Correct oAnswer: oB) oTo ocause ogoosebumps o(piloerection)
Rationale: oThe oarrector opili ois oa osmall osmooth omuscle oattached oto oeach ohair ofollicle.
When oit ocontracts, oit opulls othe ohair oupright, ocreating ogoosebumps. oIn oanimals, othis
o
helps otrap oair ofor oinsulation; oin ohumans, oit ois oa ovestigial oreflex o.

o
A) oEccrine oglands oare ofound oonly oin othe oaxillae oand ogroin; oapocrine oglands oare
found oall oover othe obody
o
B) oApocrine oglands oproduce oa owatery osecretion ofor othermoregulation; oeccrine
glands oproduce oa othick osecretion othat odevelops oodor
o
C) oEccrine oglands oare oinvolved oin othermoregulation; oapocrine oglands obecome oactive
at opuberty oand oproduce oodor owhen obroken odown oby obacteria
o
D) oApocrine oglands oare omerocrine; oeccrine oglands oare oholocrine
Correct oAnswer: oC) oEccrine oglands oare oinvolved oin othermoregulation; oapocrine
