You are watching: Which of the following is a dry membrane exposed to the air?


Which that the adhering to statements is INCORRECT?>Simple columnar epithelia are linked with absorption and also secretion.>Stratified squamous epithelia are found in locations subjected come wear and also tear.>Simple cuboidal epithelia are found in locations that stretch.>Simple squamous epithelia are linked with filtration and exchange.
>Simple cuboidal epithelia are discovered in areas that stretch. Stratified squamous epithelium (like you would uncover in the skin) is adjusted for protection, no absorption indigenous the external environment.
Which tissues have little to no practical regenerative capacity?>cardiac muscle and also nervous tissue in the brain and spinal cord>epithelial tissue, bones, and also areolar connective tissue>nervous tissue and also smooth muscle>cardiac and smooth muscle
>Cardiac muscle and also nervous tissue in the mind and spinal cord.Cardiac muscle and also the nervous tissue in the mind and spinal cord have virtually no sensible regenerative capacity, and also they are regularly replaced through scar tissue.
>False. Smooth muscle cells perform not contain striations. Back they execute contain myofilaments, their setup is not continuous enough to create the striations watched in skeletal or cardiac muscle cells.
Which building is most regular in the majority of connective tissues? > large amounts of ground problem > huge number the connective fibers > greater amount of extracellular matrix contrasted to cellular content > avasculartiy
What carry out the glands displayed in A and also B both have in common?>Both are unicellular. >Both are exocrine glands. >Both room endocrine glands. >Both room sebaceous glands.
Why room adipose tissue, blood, and bone all thought about to it is in connective tissues?>They have the same species of cells.>They all have collagen and also elastic yarn in their extracellular matrix.>They have actually a typical origin: mesenchyme.>They attach to every other.
>They have a usual origin: mesenchyme. Every are component of the mesoderm.Adipose tissue, bone, and also blood (like every connective tissues) are acquired from mesenchyme, an embryonic tissue. Additionally common to all connective tissues is the presence of cells and an extracellular procession that is composed of yarn bathed in floor substance.
Under a microscope you watch a tissue that shows up to have long yarn that show up striated. The nuclei are driven off to the side of the fibers. The tissue looks really vascular. What kind of tissue room you observing?>dense irregular connective tissue>dense constant connective tissue>skeletal muscle tissue>osseous tissue
Skeletal Muscle Tissue. The striations are proof of the myofilaments within the muscle fibers. The position of the nuclei and vascularity are additionally signs that muscle tissue.
You observe a tissue under a microscope. There shows up to it is in a lumen top top one next of the tissue. Lining this lumen, the cell seem to have actually long, fingerlike projections. Beneath the projections, the cell seem to have actually the form of shoeboxes and are packed tightly together. What kind of tissue space you feather at? >stratified squamous epithelia >simple columnar epithelia >simple cuboidal epithelia >transitional epithelia
>Simple columnar epithelia. The shoebox to represent the columnar shape. Additionally, the fingerlike projections are most likely to be microvilli.
Which that the complying with statements is true? >Dense connective tissue consists of a good deal the collagen. >Loose connective tissue consists of cartilage. >Dense connective tissue includes a huge amount the reticular fibers. >All subclasses of loosened connective tissue perform not contain collagen fibers.
>Dense connective tissue has a an excellent deal of collagen. Correct, the prominent facet of dense connective tissue space the fibers. Dense constant connective organization primarily has actually parallel collagen fibers and a couple of elastic fibers. Thick irregular connective tissue primarily has actually irregularly arranged collagen fibers and also some elastic fibers. Elastic connective tissue includes a high ratio of elastic fibers.
What distinguishes the gland in A native the gland in B?>the use of a duct >the use of epithelial cell to produce assets >the method of secretion >the direct secretion of assets into the blood
>The an approach of secretion. The gland in A is secreting in a merocrine manner, if B is secreting in a holocrine manner.
Pseudostratified epithelia are well adapted to the cradle system since the cilia boost the surface ar area because that absorption.>True>False
>False. Pseudostratified epithelia are discovered in the respiratory linings. Cilia are used for movement, not raising surface area.
Which is the most atypical connective tissue because it does not act together a binding or packaging material under normal conditions or provide structural support? >cartilage >osseous > areolar connective organization >blood
>Blood. Blood, the fluid connective organization (CT) within blood vessels, is the many atypical CT. It does not act together a binding or packing material; the does not provide structural support. The is classified together a CT only due to the fact that it creates from mesenchyme and also consists of cell (blood cells) surrounded by an extracellular liquid matrix (blood plasma).
Which that the following substances would certainly NOT be found in significant amounts in the extracellular matrix of the shown areolar connective tissue?>elastin >proteoglycan >collagen >keratin
>Keratin. Keratin is a protein frequently found in epithelial tissues, notably the cornified great of the epidermis. Keratin would as such not be uncovered in significant quantities in the ECM the connective tissues.
You watch a uniform tissue under a microscope. There is no lumen. The product looks densely packed, but you do not observe numerous nuclei. It appears that there room strands the fibers running in parallel directions. What kind of tissue room you feather at? >epithelial tissue >nervous organization >muscle organization >connective tissue
>Connective tissue. Friend are probably looking at dense consistent connective tissue. Connective tissue has a short cell count compared to the extracellular matrix.
>Absorption. Absorption, the activity of substances into the body, is a role of epithelial tissue. Duties of connective tissue incorporate binding and support, protection, insulation, and also transportation of substances, via blood, within the body.
Cutaneous membrane describes that of the skin. Mucous membranes room specifically connected in the respiratory tract cavity. Serous membranes include the respiratory/abdominal cavities.
All epithelia have two surfaces, an apical surface and also a basal surface, that differ in both structure and also function. This property is called polarity.>True>False
>True. All epithelia exhibition polarity, i m sorry is defined by the presence of one apical, or free, surface and a basal, or attached, surface ar that differ in both structure and function.
Which of the complying with is a dry membrane exposed come the air?>cutaneous membrane>synovial membrane>mucous membrane>serous membrane
>cutaneous membrane. The cutaneous membrane is your skin, an body organ consisting that a keratinized stratified squamous epithelium (epidermis) steady attached to a special layer that connective tissue (dermis). Unlike various other epithelial membranes, the cutaneous membrane is exposed to the air and also is a dried membrane.
Injured cartilage might heal more quickly if a treatment were found that would __________.>prevent chondrocytes native dividing and also thereby to reduce the family member amount of procession that is present in the cartilage>stimulate blood vessels to build within cartilage>stimulate calcification the cartilage>All that the noted responses space correct.
>Stimulate blood vessels to develop within the cartilage. Cartilage is usually avascular, so nutrients forced for healing should diffuse from far-off blood vessels, i m sorry delays the heal process.
How room endocrine and also exocrine glands different from every other?>Exocrine glands are just unicellular in structure.>Exocrine glands secrete hormones.>Exocrine glands have details target organs for their secretions.>Endocrine glands have actually no ducts.
>Endocrine glands have actually no ducts. Endocrine glands secrete substances (hormones) right into blood without the use of ducts, conversely, exocrine glands usage ducts come secrete substances into the outside environment.
Which the the following statements is INCORRECT?>Mucous membranes line exits and also entrances to the body.>The cutaneous membrane is a dried membrane exposed come air.>Serous membranes line human body cavities and also organs.>The cutaneous membrane is make of a simple columnar epithelium
>The cutaneous membrane is make of straightforward columnar epithelium. The cutaneous membrane, a "dry" membrane exposed to air, consists of a keratinized, stratified squamous epithelium dubbed the epidermis, and an basic layer that connective tissue called the dermis.
Which event must precede all others during tissue repair?>Clotting wake up in the damaged area.>Inflammation occurs near the influenced cells.>Epithelia reproduce and migrate to the damaged area.>Fibroblasts develop collagen that strengthens the area surrounding the tissue damage.
>Inflammation occurs near the impacted cells. Inflammation is the an initial part the the organization repair. The inflammation events set the stage for the organization repair process.
Connective tissues are made of various combinations of floor substance and fibers. Together you compare slides that connective tissues, which would most likely be the strongest type of connective tissue based upon the composition of floor substance and also fibers?>connective tissues high in collagen fibers>connective organization high in elastic fibers>connective organization high in reticular fibers>connective organization high in ground substance
>Connective organization high in collagen fibers. Collagen is the toughest the the fibers. If you saw collagen in high amounts, the would show strength in the connective tissue.
