Stratum basale - Germinatinne layer
Stratum spinosum - Prikle – cell layer
Stratum
granulosum - Granular layer
Stratum lucidum - lucid layer
Stratum corneum - Horny layer

Слайд 5Epidermis
1.Stratum basale (germinative layer)
Keratinoblastis (1 layer, like a polisade).
Melanoblastis (their ratio
is 1:11 to keratinoblastis).
young cells, are devided by mitosis, and form all the structures of epidermis.
Melanin is formed in the melanoblastis and protects the skin from ultraviolet rays.

2. Stratum spinosum (pricle-cell layer)
Dendritic epidermocytis (5-7 layers)
Langhan’s cells
Hrenstayin’s cells
3. Stratum
granulosum (granular layer)
1-2 layers of elongated cells. There are keratohyalinis granuls in the protoplasm of these cells.

Слайд 7Epidermis
4. Stratum lucidum (lucid layer)
These cells contain eleidin. Str. lucidum
contains glycogens, lipoids, fatty acids.
5. Stratum corneum (horny layer)
It is composed of fine, anuclear keratinised elongated cells containing keratin.

Слайд 8Dermis
(the true skin)
Structural amorphous interstitial substance:
collagenous fibres
elastics fibres

Epithelial appendages of the skin
Слайд 11Protective (barrier) functions of the skin
Protects the organism from the
damaging effect of sun rays
Physiology desquamation
Protect the underlying tissue from drying
Homogeneous tightness of substanal protects from mechanical effects (blows, friction, compression)

Слайд 12Protective (barrier) functions of the skin
An acid (pH5.0-6,0) water-lipid mantle
which attenuatus or neutralizis the damaging effect of chemical substances.
Bactericidal properties of sweat (lisocini) and sebum (squaleni)
Immynological function. Skin associated limphoid tissue. Salt
Resistance to electric current
