INTEGUMENTARY SYSTEM Flashcards
The integumentary system contains the __that detect arriving stimuli from the external
environment.
sensory organs
the integumentary system has two layers, separated by a
__: the __, the surface layer; and below it is the __.
basement membrane
epidermis
dermis
The invagination of the
epidermis forms __, both __ and
__.
skin glands
exocrine glands
endocrine glands
Interaction between two layers (of skin) stimulates the formation of __ such as teeth, feathers, hair, and scales of several varieties
specialized structures
The integument is considered to be one of the largest organs of the body making up some __ of the human body weight

layers of the integumentary system of amphibians (frog)
epidermis
dermis
(2) layers of the integumentary system of frogs
stratum germinativum
stratum corneum
layer of the integumentary system of frogs (epidermis)
innermost layer
stratum germinativum
layer of the integumentary system of frogs (epidermis)
outermost layer
stratum corneum
layer of the integumentary system of frogs
outermost layer
epidermis
layer of the integumentary system of frogs
deep layer
dermis
(3) layer of the dermis of frogs
stratum spongiosum
stratum compactum
subcutaneous layer
layer of the dermis of frogs
lies immediately below the stratum germinativum. There are various specialized structures associated with this layer
stratum spongiosum
layer of the dermis of frogs
thickest layer, made up of connective tissue fibers which are arranged horizontally
stratum compactum
layer of the dermis of frogs
the deep extension of the dermis, usually containing adipose tissue
subcutaneous layer
(3) specialized structures asociated with the stratum spongiosum of frogs
melanophores
mucous glands
poison glands
specialized structure asociated with the stratum spongiosum of frogs
lines the stratum spongiosum, a specific type of __ (pigment cell) that produces a brown or black pigment
melanophores
chromatophore
specialized structure asociated with the stratum spongiosum of frogs
secretes slimy secretion
mucous gland
specialized structure asociated with the stratum spongiosum of frogs
secrete toxic substances. Only present in poisonous amphibians
poison glands
(3) structures in mucous glands of frogs
mouth
neck
body/fundus
structure in mucous glands of frogs
open onto the surface
mouth
structure in mucous glands of frogs
a duct leading to the mouth
from the body or fundus
beck
the outermost layer of the skin,
differentiated into 5 layers of the integumentary system of mammals (humans)
epidermis
integ. of humans
innermost, thicker layer of the skin, differentiated into 3 layers
dermis
(5) layerof the epidermis of humans
stratum basale/germinativum
stratum spinosum
stratum granulosum
stratum lucidum
stratum corneum
layer of the epidermis of humans
innermost layer, where cells are produced continually and migrate toward the surface
stratum basale/germinativum
layer of the epidermis of humans
immediately superficial to
stratum basale.
stratum spinosum
layer of the epidermis of humans
a granular layer peripheral to the stratum spinosum
stratum granulosum
layer of the epidermis of humans
third layer, lies just above the stratum granulosum. This layer occurs in thick skin, also immediately deep to the stratum
corneum.
stratum lucidum
layer of the epidermis of humans
the outer layer of cells with
cornified cytoplasm.
stratum corneum
layer of epidermis in humans that is absent in thin skin
stratum lucidum
(6) epidermal derivatives
sebaceous glands
sweat glands
arrector pili muscle
hair shaft
hair follicle
hair bulb/papilla
epidermal derivative
arise from the walls of the hair follicle
sebaceous glands
epidermal derivative
coiled tube, numerously
distributed within the dermal layer
sweat glands
epidermal derivative
tiny dandles of smooth muscle associated with hair follicles
arrector pili muscle
epidermal derivative
exposed part of the hair
hair shaft
epidermal derivative
the pit in the skin from which
each hair springs
hair follicle
epidermal derivative
situated at the bottom of the hair follicle.
hair bulb/papilla
(3) layers of the dermis of humans
papillary layer
reticular layer
subcutaneous layer
layer of the dermis of humans
contains many small finger-like
projections called __, marking the upper region of the dermis projecting into the epidermis
papillary layer
papillae
layer of the dermis of humans
region below the papillary layer
reticular layer
layer of the dermis of humans
the deep extension of the
dermis, usually including adipose tissue
subcutaneous layer
