Integumentary System Flashcards
the most superficial layer of skin
epidermis
a layer of dense connective tissue
dermis
prevents water loss and resists abrasion
epidermis
The epidermis, known as the cutaneous
membrane, is a ______________.
keratinized stratified squamous epithelium
most superficial
stratum of the epidermis, consists of dead
squamous cells filled with keratin
stratum corneum
Excessive sloughing of stratum corneum cells
from the surface of the scalp is called
dandruff
In skin subjected to friction, the number of
layers in the stratum corneum greatly increases,
producing a thickened area called a
callus
Over a bony prominence, the stratum corneum
can thicken to form a cone-shaped structure
called a
corn
dermis is composed of ____________ containing fibroblasts, adipocytes, and macrophages
dense collagenous connective tissue
tension lines, in the skin, are more resistant to stretch
cleavage lines
the group of pigments primarily responsible for skin, hair, and eye color.
melanin
a yellow pigment found in plants such
as squash and carrots
carotene
Although many genes are responsible for skin
color, a single mutation can prevent the
production of melanin and cause ____________.
albinism
A decrease in the blood O2 content produces a
bluish color of the skin, called _____________
cyanosis
invagination of epidermis
hair follicle
