Integumentary, Muscular and Skeletal Flashcards
Outer covering othe body
Integument
Structure derived from the skin
Hair
Setae
Scales
Feahers
Horns
Have only delicate cell or plasma membrane for covering
Unicellular eukaryotes
Single-celled freshwater animal that developed a protectiv pellicle
Paramecium
The principle single-layered covering in most invertebrates skin
Epidermis
A noncellular _____ is added over the epidermis by some invertebrates
Cuticle
Phylum platyhelminthes has this that is resistant to immune responses of host and to digestion by host enzymes
Synctial tegument
This epidermis is delicate and soft and contain mucuos gland , where some secretes calcium carbonate
Molluscs epidermis
It has an integument consisting from surafce in ward of cuticle, simple epidermis, layers of connective tissue, layers of reflectig cells, and thicker layers of connective tissue
Cephalopod molluscs
Have the most complex of invertebrate integuments
Arthropods
In arthropod, thi is a single-layered that secretes a complex cuticle of two zones
Hypodermis
In arthropods, this is the thicker zone composed of protein and chitin
Procuticle
In arthropods, this is the outer zone of cuticle lying on external surface abov procuticle. It is nonchitinous
Epicuticle
Thi is the process undergone when cuticle is stiffened, and ther is the deposition of calcium carbonate in the outer layers of procuticl
Calcification
It is the process where insects hardening occurs due to protein molecules bonded together with stabilizing cross-linkages within an between adjacent lamellae
Sclerotization
During sclerotization, there is the formation of highly resistant and insoluble protein called
Sclerotin
What type of layer does the Epidermis of verterate have?
Stratified Squamous Epithelium
This is the true skin and it has a mesodermal origin
Dermis
Fibrou proteins that accumulate the interior o the cell
Keratin
The process where keratin accumulate the interior o the cell
Keratinization
When keratin replaces all metabolically acive cutoplasm the cell becomes?
Cornified
What does cornified cells forms
Stratum corneum
The dermal layers becomes especially thick in areas exposed to persitent pressure or wear which eventually becomes______
Callus
Connective tissu of dermis
Dense-connective tissue layer
