Which that the adhering to epithelial tissue varieties is NOT appropriately matched to its function?>simple squamous epithelium; filtration>simple cuboidal epithelium; secretion>simple columnar epithelium through microvilli; absorption>stratified squamous epithelium; absorption
>Stratified squamous epithelium; absorption. Stratified squamous epithelium (like friend would find in the skin) is adjusted for protection, not absorption from the external environment.

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

Which the the adhering to statements is INCORRECT?>Simple columnar epithelia are connected with absorption and also secretion.>Stratified squamous epithelia are uncovered in areas subjected come wear and tear.>Simple cuboidal epithelia are found in areas that stretch.>Simple squamous epithelia are linked with filtration and exchange.
>Simple cuboidal epithelia are discovered in areas that stretch. Stratified squamous epithelium (like girlfriend would find in the skin) is adjusted for protection, not absorption native the exterior environment.
Which organization have little to no sensible 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 smooth muscle>cardiac and also smooth muscle
>Cardiac muscle and nervous tissue in the brain and spinal cord.Cardiac muscle and the nervous tissue in the mind and spinal cord have actually virtually no sensible regenerative capacity, and they are on regular basis replaced by scar tissue.
>False. Smooth muscle cells perform not save on computer striations. Return they carry out contain myofilaments, their setup is not regular enough to generate the striations seen in skeletal or cardiac muscle cells.
Which home is most regular in the majority of connective tissues? > big amounts that ground problem > big number that connective fibers > higher amount that extracellular matrix compared to cellular content > avasculartiy
What perform the glands presented in A and B both have in common?>Both room unicellular. >Both space exocrine glands. >Both space endocrine glands. >Both room sebaceous glands.
Why space adipose tissue, blood, and also bone all taken into consideration to be connective tissues?>They have the same types of cells.>They all have collagen and also elastic yarn in your extracellular matrix.>They have actually a typical origin: mesenchyme.>They attach to every other.
>They have actually a common origin: mesenchyme. Every are part of the mesoderm.Adipose tissue, bone, and blood (like all connective tissues) are derived from mesenchyme, one embryonic tissue. Also common to every connective tissues is the presence of cells and an extracellular matrix that is composed of fibers bathed in soil substance.
Under a microscope you watch a tissue that appears to have long yarn that show up striated. The nuclei are pushed off come the next of the fibers. The organization looks an extremely vascular. What kind of tissue room you observing?>dense rarely often rare connective tissue>dense continuous connective tissue>skeletal muscle tissue>osseous tissue
Skeletal Muscle Tissue. The striations are evidence of the myofilaments within the muscle fibers. The place of the nuclei and vascularity are also signs the muscle tissue.
You watch a tissue under a microscope. There appears to be a lumen ~ above one side of the tissue. Lining this lumen, the cells seem to have actually long, fingerlike projections. In ~ the projections, the cell seem to have actually the form of shoeboxes and are pack tightly together. What type of tissue space you feather at? >stratified squamous epithelia >simple columnar epithelia >simple cuboidal epithelia >transitional epithelia
>Simple columnar epithelia. The shoebox represents the columnar shape. Additionally, the fingerlike projections are most likely to be microvilli.
Which the the adhering to statements is true? >Dense connective tissue contains a an excellent deal of collagen. >Loose connective tissue consists of cartilage. >Dense connective tissue includes a huge amount of reticular fibers. >All subclasses of loose connective tissue do not save on computer collagen fibers.
>Dense connective tissue contains a an excellent deal that collagen. Correct, the prominent element of thick connective tissue are the fibers. Dense consistent connective organization primarily has actually parallel collagen fibers and also a couple of elastic fibers. Thick irregular connective organization primarily has actually irregularly i ordered it collagen fibers and some elastic fibers. Elastic connective tissue contains a high proportion of elastic fibers.
What distinguish the gland in A indigenous the gland in B?>the usage of a duct >the use of epithelial cell to produce commodities >the an approach of cheap >the straight secretion of commodities into the blood
>The technique of secretion. The gland in A is secreting in a merocrine manner, when B is secreting in a holocrine manner.
Pseudostratified epithelia space well adapted to the cradle system due to the fact that the cilia boost the surface area because that absorption.>True>False
>False. Pseudostratified epithelia are uncovered in the respiratory linings. Cilia are supplied for movement, not boosting surface area.
Which is the many atypical connective tissue because it does no act as a binding or packaging material under normal conditions or carry out structural support? >cartilage >osseous > areolar connective tissue >blood
>Blood. Blood, the liquid connective tissue (CT) in ~ blood vessels, is the many atypical CT. The does not act together a binding or packing material; it does not administer structural support. That is classified together a CT only since it develops from mesenchyme and also consists of cell (blood cells) surrounding by one extracellular fluid matrix (blood plasma).
Which that the following substances would NOT be found in far-ranging amounts in the extracellular matrix of the portrayed areolar connective tissue?>elastin >proteoglycan >collagen >keratin
>Keratin. Keratin is a protein frequently found in epithelial tissues, notably the cornified class of the epidermis. Keratin would thus not be discovered in far-reaching quantities in the ECM that connective tissues.
You watch a uniform organization under a microscope. There is no lumen. The material looks densely packed, however you carry out not observe numerous nuclei. It shows up that there room strands that fibers running in parallel directions. What type of tissue are you spring at? >epithelial tissue >nervous organization >muscle organization >connective tissue
>Connective tissue. You are probably looking in ~ dense consistent connective tissue. Connective tissue has a low cell count compared to the extracellular matrix.
>Absorption. Absorption, the activity of substances right into the body, is a duty of epithelial tissue. Roles of connective tissue encompass binding and also support, protection, insulation, and also transportation of substances, via blood, within the body.
Cutaneous membrane refers to that that the skin. Mucous membranes are specifically connected in the respiratory cavity. Serous membranes incorporate the respiratory/abdominal cavities.
All epithelia have actually two surfaces, an apical surface and also a basal surface, the differ in both structure and also function. This residential or commercial property is referred to as polarity.>True>False
>True. Every epithelia exhibit polarity, i beg your pardon is characterized by the existence of an apical, or free, surface and also a basal, or attached, surface that differ in both structure and function.
Which that 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 come a thick layer that connective organization (dermis). Unlike various other epithelial membranes, the cutaneous membrane is exposed to the air and is a dried membrane.
Injured cartilage can heal much more quickly if a treatment were found that would certainly __________.>prevent chondrocytes from dividing and also thereby reduce the loved one amount of matrix that is existing in the cartilage>stimulate blood vessels to develop within cartilage>stimulate calcification that cartilage>All that the detailed responses room correct.
>Stimulate blood vessels to build within the cartilage. Cartilage is normally avascular, for this reason nutrients compelled for healing should diffuse from far-off blood vessels, i m sorry delays the heal process.
How are endocrine and exocrine glands various from each other?>Exocrine glands are just unicellular in structure.>Exocrine glands secrete hormones.>Exocrine glands have certain target organs for their secretions.>Endocrine glands have no ducts.
>Endocrine glands have actually no ducts. Endocrine glands secrete building material (hormones) into blood there is no the usage of ducts, vice versa, exocrine glands use ducts come secrete substances into the outside environment.
Which of the adhering to statements is INCORRECT?>Mucous membranes line exits and entrances to the body.>The cutaneous membrane is a dry membrane exposed come air.>Serous membranes line body cavities and also organs.>The cutaneous membrane is made of a basic columnar epithelium
>The cutaneous membrane is made of straightforward columnar epithelium. The cutaneous membrane, a \"dry\" membrane exposed to air, consists of a keratinized, stratified squamous epithelium dubbed the epidermis, and also an underlying layer that connective tissue called the dermis.
Which event must precede every others throughout tissue repair?>Clotting wake up in the damaged area.>Inflammation occurs close to the influenced cells.>Epithelia reproduce and also migrate come the damaged area.>Fibroblasts produce collagen that strengthens the area neighboring the tissue damage.
>Inflammation occurs near the affected cells. Inflammation is the an initial part of the organization repair. The inflammatory events collection the phase for the organization repair process.
Connective tissues are made of various combinations of soil substance and also fibers. Together you compare slides the connective tissues, which would certainly most most likely be the strongest kind of connective tissue based on the composition of floor substance and also fibers?>connective tissues high in collagen fibers>connective tissue high in elastic fibers>connective organization high in reticular fibers>connective tissue high in soil substance
>Connective organization high in collagen fibers. Collagen is the toughest that the fibers. If you experienced collagen in high amounts, that would show strength in the connective tissue.

After a heart attack, fibrosis occurs at the website of cardiac muscle cell death. This reduces the efficiency of the heart\"s pumping task because __________.>the undamaged cardiac muscle cells come to be fatigued indigenous the power expended during the healing process>fibrous connective organization is i can not qualify of contracting>fibrosis produces new cardiac muscle cells that room not as solid as the maturation ones that died>the initial fatality of part cardiac muscle cell triggers a chain reaction in which progressively an ext and more neighboring healthy cells die
>Fibrous connective organization is i can not qualify of contracting. Cardiac muscle includes sarcomeres, which enable for the tissue to contract once electrically stimulated. Fibrous connective tissue lacks these one-of-a-kind contractile units.
