integumentary system Flashcards
type of tissue for epidermis
stratified squamous epithelium
type of tissue for papillary layer of dermis
loose connective tissue
type of tissue for reticular layer of dermis
dense irregular connective tissue
type of tissue for hypodermis
primarily adipose tissue
two main layers of the skin and underlying tissue
epidermis
dermis
the five layers of the epidermis
stratum corneum stratum lucidium stratum granulosum stratum spinosum stratum basale
layer of translucent cells, absent in thin skin
lucidum
strays containing all dead cells
corneum
vascular layer
dermis
hypodermis
actively motor ic epidermal region, the deepest, epidermal layer
basale
cells are flat, dead “bags” of keratin
corneum
site of elastic and collagen fibers
dermis
hypodermis
general site of melanin formation
epidermis
major skin area where derivatives reside
dermis
largely adipose tissue; anchors the skin to underlying tissues
hypodermis
epidermal later where most melanocytes are found
basale
produces keratohyalin granules
granulosum
accounts for the bulk of epidermal thickness
corneum
when tanned, becomes leather; provides mechanical strength to skin
dermis
most responsible for the skin color of dark skinned people
melanin
provides an orange cast to the skin
carotene
provides a natural sunscreen
melanin
most responsible for the skin color of caucasians
hemoglobin
phagocytized by keratinocytes
melanin
found within red blood cells in the blood vessels
hemoglobin
a bluish cast of the skin resulting from inadequate oxygenation of the blood
cyanosis
observation of this condition might lead to tests for anemia or low blood pressure
pallor
accumulation of bile pigments in the blood; may indicate liver disease
jaundice
clotted mass of blood that may signify bleeders disease
hematoma
a common result of inflammation, allergy, and fever
erythema
