Week 4 - Skin Care 1 - Assignment - Skin Anatomy Part 1
Langerhans cells are:
star shaped immune cells in the epidermis
What epidermal layer or stratum is continually being shed and replaced
corneum
The epidermis of the skin, hair, nails are all made of a protein called keratin. tf
t
The body is cooled by evaporation through the sebaceous glands. tf
f
This substance is found between the cells in the epidermis:
intercellular cement
When the skin is injured Macrophage cells produce histamine which brings blood (and white blood cells) to the injured area.
tf
f
The normal or natural process by which cells are sloughed off the stratum corneum is known as
desquamation
What epidermal layer or stratum is partially dead and helps to produce the "mortar" that holds the cells of the epidermis together
granulosum
Cells in the stratum spinosum develop prickly spines called desmosomes that attach cells together and assist in the development of the skin's barrier function.tf
t
The ability of the skin to protect against invasion by offending or injurious substances as well as the ability to keep moisture in is known as the "barrier function" of the skin. tf
t
In the stratum granulosum, lipids are produced that will become part of the ground substance.tf
f
The average of the body's internal thermostat is set at 89.6 degrees F. tf
f
By providing a barrier against micro-organisms and irritating chemicals skin is performing which of its functions
protection

protection
Melanocytes are:
pigment cells
What epidermal layer or stratum is totally dead, dried out, scaly and can be seen as it flakes off:
corneum
Although it slows with age, skin's average rate of cell turnover in those in their twenties is approximately:
28-30 days
Over half of the body`s primary immune cells are found in the epidermis including Mast cells, Langerhans cells, Macrophages, Basal cells and Desmosomes.tf
f
The skin regulates body temperature in hot weather by
causing the dilation of blood vessels
corneocytes are
flattened cells at the skin's surface
Melanocytes are the pigment which protects us from UV rays.tf
f
Desquamation is the term for the normal process in which cells move to the surface of the epidermis and are naturally shed.tf
f
Melanocytes are found in which stratum
germanitivum
Cells of the skin replicate themselves through a process of cell division known as mitosis tf
t
Cells of the skin replicate themselves through a process of cell division known as mitosis tf
t
Exfoliation is the forced removal of dead cells from the stratum corneum and it helps to speed up the skins' natural rate of cell turnover and the production of intercellular cement by sending a message from the stratum germinativum to the stratum corneum. tf
f
What epidermal layer or stratum is a row of cells that are totally living:
germanitivum
What epidermal layer or stratum manufactures cells for the rest of the epidermis
germanitivum
The stratum corneum is also known as the horny layer. tf
t
What area of the body would the stratum lucidum be found
palms and soles
Mast cells and Langerhans cells are part of the skin's immune system.tf
t
In what layer or stratum of the skin does cell division occur continuously:
germanitivum
The lack of water between the cells of the epidermis leads to TEWL. tf
t
Esthetics is defined as a branch of anatomical science that deals with the beauty and the appearance of the skin. tf
