What |are |the |4 |types |of |tissues? |- |correct |answer |-epithelial, |connective, |muscle, |nervous
What |are |the |five |layers |of |the |epidermis? |(from |superficial |to |deep) |- |correct |answer |-stratum |
basale, |stratum |spinosum, |stratum |granulosum, |stratum |lucidum, |stratum |corneum
Where |in |the |5 |layers |of |the |epidermis |do |you |release |the |most |keratin? |- |correct |answer |-Stratum
|corneum
What |are |the |3 |layers |of |the |skin? |- |correct |answer |-epidermis, |dermis, |hypodermis
Among |the |three |layers |of |skin, |which |layer |acts |as |a |barrier |and |provides |protection |against |
bacteria? |- |correct |answer |-The |dermis |contains |phagocytes, |which |are |cells |that |consume |
potentially |harmful |toxins |and |impurities, |including |bacteria.
what |is |the |function |of |the |hypodermis? |- |correct |answer |-The |hypodermis |insulates |your |body, |
protects |your |body |from |harm, |stores |energy |and |connects |your |skin |to |your |muscles |and |bones.
The |hypodermis |is |the |innermost |layer |of |skin.
What |is |the |function |of |the |dermis? |- |correct |answer |-The |dermis |supports |and |protects |the |skin |
and |deeper |layers, |assist |in |thermoregulation, |and |aids |in |sensation. |
The |dermis |is |the |middle |region.
The |dermis |is |a |fibrous |structure |composed |of |collagen, |elastic |tissue, |and |other |extracellular |
components |that |includes |vasculature, |nerve |endings, |hair |follicles, |and |glands
What |is |the |function |of |the |epidermis? |- |correct |answer |-The |epidermis |is |composed |of |keratinized |
stratified |squamous |epithelium, |consisting |of |4 |distinct |cell |types. |The |cell |types |include |
, keratinocytes, |melanocytes, |merkel |cells, |and |langerhans |cells. |The |outer |portion |of |the |skin |is |
exposed |to |the |external |environment |and |functions |in |protection.
The |epidermis |is |the |outermost |layer |of |skin.
What |are |epidermal |ridges? |- |correct |answer |-fingerprints
what |type |of |epithelial |tissue |do |you |find |in |the |epidermis? |- |correct |answer |-Stratified |squamous |
epithelium
which |protein |reduces |water |loss |in |skin?(prevents |dehydration) |- |correct |answer |-keratin
how |many |layers |of |the |epidermis |would |be |affected |if |the |entire |sole |of |your |foot |is |penetrated? |-
|correct |answer |-All |five |layers.
what |are |the |names |of |the |accessory |structures? |- |correct |answer |-hair, |nails, |sweat |glands, |and |
sebaceous |glands.
What |does |is |mean |when |something |is |vascular |or |avascular? |- |correct |answer |-vascular- |has |blood |
vessels
avascular- |no |blood |vessels
out |of |the |3 |layers |of |skin, |which |are |vascular |and |avascular? |- |correct |answer |-Dermis- |vascular
epidermis-avascular
hypodermis-vascular
which |layer |of |skin |have |larger |blood |vessels? |- |correct |answer |-dermis
where |do |you |find |blood |vessels |in |the |layers |of |skin? |- |correct |answer |-dermis
