>Stratified squamous epithelium; absorption. Stratified squamous epithelium (like you would discover in the skin) is adjusted for protection, no absorption native the exterior environment.
You are watching: Which tissues have little to no functional regenerative capacity
Which that the complying with statements is INCORRECT?>Simple columnar epithelia are associated with absorption and also secretion.>Stratified squamous epithelia are found in areas subjected to wear and also tear.>Simple cuboidal epithelia are uncovered in locations that stretch.>Simple squamous epithelia are linked with filtration and exchange.
>Simple cuboidal epithelia are discovered in locations that stretch. Stratified squamous epithelium (like girlfriend would uncover in the skin) is adapted for protection, no absorption indigenous the exterior environment.
Which organization have tiny to no useful regenerative capacity?>cardiac muscle and nervous organization in the brain and spinal cord>epithelial tissue, bones, and areolar connective tissue>nervous tissue and also smooth muscle>cardiac and also smooth muscle
>Cardiac muscle and nervous tissue in the mind and spinal cord.Cardiac muscle and also the nervous organization in the brain and spinal cord have actually virtually no practical regenerative capacity, and they are routinely replaced by scar tissue.
>False. Smooth muscle cells execute not save striations. Although they carry out contain myofilaments, their setup is not regular enough to generate the striations watched in skeletal or cardiac muscle cells.
Which residential property is most continuous in the bulk of connective tissues? > huge amounts of ground substance > big number of connective fibers > better amount of extracellular matrix contrasted to cellular contents > avasculartiy
What do the glands presented in A and B both have actually in common?>Both space unicellular. >Both space 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 varieties of cells.>They all have collagen and elastic yarn in their extracellular matrix.>They have actually a common origin: mesenchyme.>They affix to every other.
>They have a common origin: mesenchyme. All are part of the mesoderm.Adipose tissue, bone, and also blood (like all connective tissues) are acquired from mesenchyme, an embryonic tissue. Additionally common to all connective organization is the existence of cells and an extracellular matrix that consists of yarn bathed in floor substance.
Under a microscope you observe a organization that appears to have long yarn that show up striated. The nuclei are moved off to the side of the fibers. The tissue looks really vascular. What kind of tissue are you observing?>dense rarely often, rarely connective tissue>dense constant connective tissue>skeletal muscle tissue>osseous tissue
Skeletal Muscle Tissue. The striations are proof of the myofilaments inside the muscle fibers. The place of the nuclei and vascularity are likewise signs the muscle tissue.
You watch a organization under a microscope. There appears to it is in a lumen ~ above one side of the tissue. Lining this lumen, the cells seem to have long, fingerlike projections. Beneath the projections, the cell seem to have the form of shoeboxes and are pack tightly together. What kind of tissue are you spring 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 it is in microvilli.
Which of the adhering to statements is true? >Dense connective tissue consists of a good deal that collagen. >Loose connective tissue has cartilage. >Dense connective tissue has a large amount that reticular fibers. >All subclasses of loosened connective tissue perform not contain collagen fibers.
>Dense connective tissue contains a an excellent deal the collagen. Correct, the prominent element of thick connective tissue room the fibers. Dense continuous connective tissue primarily has actually parallel collagen fibers and a couple of elastic fibers. Dense irregular connective tissue primarily has irregularly i ordered it collagen fibers and also some elastic fibers. Elastic connective tissue has a high relationship of elastic fibers.
What distinguish the gland in A native the gland in B?>the use of a duct >the use of epithelial cell to produce products >the an approach of secretion >the straight secretion of assets 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 room well adapted to the digestive system because the cilia boost the surface ar area because that absorption.>True>False
>False. Pseudostratified epithelia are found in the respiratory linings. Cilia are supplied for movement, not raising surface area.
Which is the many atypical connective tissue because it does not act as a binding or packaging material under normal conditions or administer structural support? >cartilage >osseous > areolar connective tissue >blood
>Blood. Blood, the fluid connective organization (CT) in ~ blood vessels, is the most atypical CT. It does no act together a binding or packing material; the does not administer structural support. The is classified together a CT only due to the fact that it establishes from mesenchyme and consists of cell (blood cells) surrounding by one extracellular liquid matrix (blood plasma).
Which of the adhering to substances would NOT be uncovered in significant amounts in the extracellular procession of the shown areolar connective tissue?>elastin >proteoglycan >collagen >keratin
>Keratin. Keratin is a protein frequently found in epithelial tissues, especially the cornified great of the epidermis. Keratin would as such not be uncovered in far-reaching quantities in the ECM the connective tissues.
You observe a uniform tissue under a microscope. There is no lumen. The material looks densely packed, yet you do not observe numerous nuclei. It appears that there are strands of fibers running in parallel directions. What type of tissue are you feather at? >epithelial tissue >nervous tissue >muscle tissue >connective tissue
>Connective tissue. You are most likely looking at dense continual connective tissue. Connective tissue has a low cell count contrasted to the extracellular matrix.
>Absorption. Absorption, the motion of substances into the body, is a duty of epithelial tissue. Functions of connective tissue incorporate binding and support, protection, insulation, and transportation of substances, via blood, within the body.
Cutaneous membrane describes that that the skin. Mucous membranes room specifically involved in the respiratory tract cavity. Serous membranes encompass the respiratory/abdominal cavities.
All epithelia have actually two surfaces, one apical surface and also a basal surface, the differ in both structure and also function. This residential or commercial property is called polarity.>True>False
>True. Every epithelia exhibit polarity, i m sorry is defined by the visibility of an apical, or free, surface and also a basal, or attached, surface ar that differ in both structure and also function.
Which the the complying with is a dry membrane exposed to the air?>cutaneous membrane>synovial membrane>mucous membrane>serous membrane
>cutaneous membrane. The cutaneous membrane is her skin, an organ consisting that a keratinized stratified squamous epithelium (epidermis) steady attached to a thick layer the connective tissue (dermis). Unlike various other epithelial membranes, the cutaneous membrane is exposed to the air and is a dry membrane.
Injured cartilage can heal much more quickly if a therapy were discovered that would certainly __________.>prevent chondrocytes from dividing and also thereby to reduce the relative amount of matrix that is current in the cartilage>stimulate blood vessels to construct within cartilage>stimulate calcification that cartilage>All the the provided responses are correct.
>Stimulate blood ship to develop within the cartilage. Cartilage is normally avascular, so nutrients compelled for healing should diffuse from remote blood vessels, which delays the healing process.
How are endocrine and also exocrine glands different from every other?>Exocrine glands are just unicellular in structure.>Exocrine glands secrete hormones.>Exocrine glands have particular target offal for your secretions.>Endocrine glands have no ducts.
>Endocrine glands have actually no ducts. Endocrine glands secrete substances (hormones) right into blood there is no the use of ducts, conversely, exocrine glands use ducts come secrete substances into the exterior environment.
Which the the following statements is INCORRECT?>Mucous membranes heat exits and also entrances to the body.>The cutaneous membrane is a dry membrane exposed to air.>Serous membranes line human body cavities and organs.>The cutaneous membrane is do of a basic columnar epithelium
>The cutaneous membrane is do of basic 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 the connective tissue called the dermis.
Which event must precede all others throughout tissue repair?>Clotting wake up in the damaged area.>Inflammation occurs close to the affected cells.>Epithelia reproduce and also migrate come the damaged area.>Fibroblasts develop collagen that strengthens the area surrounding the organization damage.
>Inflammation occurs near the impacted cells. Inflammation is the very first part the the tissue repair. The inflammation events collection the stage for the organization repair process.
Connective tissues room made of various combinations of ground substance and also fibers. Together you to compare slides the connective tissues, which would most likely be the strongest type of connective tissue based on the composition of ground substance and also fibers?>connective tissues high in collagen fibers>connective organization high in elastic fibers>connective tissue high in reticular fibers>connective organization high in soil substance
>Connective tissues high in collagen fibers. Collagen is the toughest the the fibers. If you experienced collagen in high amounts, the would show strength in the connective tissue.
