Ch. 2 Anatomy and Physiology (set 2) Flashcards
organelle
micro-organs responsible for functions within the cells
desmosomes
small hairlike structures in the spiny layer of the epidermis
lamellar granules
control lipids that produce natural moisturizing factor
keratinization
progressive maturization of the keratin cell in the movement through the stratum corneum
lipids
fat or fatlike substances that are descriptive not chemical
cholesterol
precursor to most steroid hormones; a single molecule is called alcohol
fatty acids
One of many molecules that are long chains of lipid-carboxylic acid found in fats and oils.
ceramides
class of lipids that do not contain glycerol
reticula
netlike formation or structure; a network
elastin
Connective tissue proteins
The dermis is made of how many layers? called what?
2
papillary
reticular
What does “gags” stand for?
glycosaminoglycan
the most abundant one is:
hyaluronic acid
When we tattoo what what layer does the pigment go into to?
the outermost layer of the DERMIS
called the PAPILLARY
dermal-epidermal junction
superficial side of the dermis connected to the epidermis
papillae
projections of any kind; in the skin, papillae hold the dermis and the epidermis together
glycosaminoglycans
GAGS hyaluronic acid
most prominent in the dermis
bind water
soothing and softening the surface below
reticular dermis
sublayer of the dermis that connects the dermis to the epidermis and is home to the skin’s appendages
(nails, hair, glands)
Which layer is a cushion?
Hypodermis
Subcutaneous tissue
Where are “rete peds” and what do they do?
within the reticular dermis
hold the epidermis and the dermis together
“LIKE GLUE BETWEEN DERMIS AND EPIDERMIS”
What does the reticular dermis house?
appendages of the skin
nerves
blood vessel and is loaded with collagen, blood vessels and nerve endings
skin turgor
flexibility of the skin
adipose cells
fat cells
