>Stratified squamous epithelium; absorption. Stratified squamous epithelium (like girlfriend would find in the skin) is adjusted for protection, not absorption indigenous the external environment.
You are watching: Which tissues have little to no functional regenerative capacity?
Which of the following statements is INCORRECT?>Simple columnar epithelia are connected with absorption and secretion.>Stratified squamous epithelia are found in areas subjected to wear and tear.>Simple cuboidal epithelia are discovered in locations that stretch.>Simple squamous epithelia are linked with filtration and also exchange.
>Simple cuboidal epithelia are uncovered in areas that stretch. Stratified squamous epithelium (like you would find in the skin) is adjusted for protection, no absorption from the external environment.
Which organization have small to no functional regenerative capacity?>cardiac muscle and nervous tissue in the brain and spinal cord>epithelial tissue, bones, and areolar connective tissue>nervous tissue and smooth muscle>cardiac and smooth muscle
>Cardiac muscle and nervous tissue in the mind and spinal cord.Cardiac muscle and the nervous organization in the brain and spinal cord have virtually no practical regenerative capacity, and they are routinely replaced by scar tissue.
>False. Smooth muscle cells execute not contain striations. Although they do contain myofilaments, their arrangement is not consistent enough to generate the striations watched in skeleton or cardiac muscle cells.
Which property is most continual in the bulk of connective tissues? > huge amounts of ground substance > big number that connective fibers > higher amount that extracellular matrix compared to cellular content > avasculartiy
What perform the glands presented in A and also B both have actually in common?>Both space unicellular. >Both are exocrine glands. >Both room endocrine glands. >Both space sebaceous glands.
Why room adipose tissue, blood, and also bone all considered to be connective tissues?>They have the same types of cells.>They all have actually collagen and elastic yarn in your extracellular matrix.>They have actually a usual origin: mesenchyme.>They affix to each other.
>They have actually a typical origin: mesenchyme. Every are component 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 existence of cells and also an extracellular matrix that is composed of fibers bathed in floor substance.
Under a microscope you watch a tissue that shows up to have long fibers that show up striated. The nuclei are thrust off come the side of the fibers. The organization looks very vascular. What form of tissue are you observing?>dense rarely often, rarely connective tissue>dense consistent 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 also vascularity are additionally signs the muscle tissue.
You watch a organization under a microscope. There appears to it is in a lumen top top one side of the tissue. Lining this lumen, the cell seem to have long, fingerlike projections. Beneath the projections, the cells seem to have the form of shoeboxes and also are packed tightly together. What kind of tissue space you looking 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 that the adhering to statements is true? >Dense connective tissue contains a great deal that collagen. >Loose connective tissue includes cartilage. >Dense connective tissue has a large amount that reticular fibers. >All subclasses of loose connective tissue perform not contain collagen fibers.
>Dense connective tissue consists of a an excellent deal that collagen. Correct, the prominent facet of thick connective tissue room the fibers. Dense continuous connective tissue primarily has parallel collagen fibers and also a few elastic fibers. Thick irregular connective organization primarily has actually irregularly i ordered it collagen fibers and also some elastic fibers. Elastic connective tissue contains a high ratio of elastic fibers.
What distinguishes the gland in A from the gland in B?>the use of a duct >the usage of epithelial cell to produce assets >the technique of secretion >the direct secretion of products 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 space well adjusted to the digestive system since the cilia boost the surface area because that absorption.>True>False
>False. Pseudostratified epithelia are uncovered in the respiratory tract linings. Cilia are offered for movement, not enhancing surface area.
Which is the most atypical connective tissue since it does not act together a binding or packaging product 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 most atypical CT. It does not act together a binding or packing material; it does not administer structural support. The is classified together a CT only due to the fact that it develops from mesenchyme and also consists of cell (blood cells) surrounded by one extracellular fluid matrix (blood plasma).
Which the the complying with substances would NOT be uncovered in far-ranging amounts in the extracellular procession of the portrayed areolar connective tissue?>elastin >proteoglycan >collagen >keratin
>Keratin. Keratin is a protein commonly found in epithelial tissues, significantly the cornified layers of the epidermis. Keratin would because of this not be found in far-ranging quantities in the ECM the connective tissues.
You observe a uniform tissue under a microscope. Over there is no lumen. The product looks densely packed, yet you execute not observe many nuclei. It appears that there are strands the fibers running in parallel directions. What form of tissue are you spring at? >epithelial organization >nervous tissue >muscle tissue >connective tissue
>Connective tissue. Friend are more than likely looking at dense continual connective tissue. Connective tissue has a short cell count compared to the extracellular matrix.
>Absorption. Absorption, the activity of substances right into the body, is a function of epithelial tissue. Roles of connective tissue encompass binding and support, protection, insulation, and transportation the substances, via blood, in ~ 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 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 exhibition polarity, i beg your pardon is identified by the visibility of one apical, or free, surface and also a basal, or attached, surface that differ in both structure and also function.
Which the the adhering to 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 of connective tissue (dermis). Unlike other epithelial membranes, the cutaneous membrane is exposed to the air and also is a dry membrane.
Injured cartilage could heal an ext quickly if a therapy were uncovered that would __________.>prevent chondrocytes native dividing and thereby reduce the family member amount of procession that is current in the cartilage>stimulate blood ship to build within cartilage>stimulate calcification that cartilage>All of the noted responses room correct.
>Stimulate blood ship to construct within the cartilage. Cartilage is typically avascular, for this reason nutrients required for healing have to diffuse from remote blood vessels, which delays the healing process.
How room endocrine and exocrine glands various from each other?>Exocrine glands are just unicellular in structure.>Exocrine glands secrete hormones.>Exocrine glands have certain target offal for your secretions.>Endocrine glands have no ducts.
>Endocrine glands have no ducts. Endocrine glands secrete substances (hormones) into blood without the usage of ducts, conversely, exocrine glands usage ducts to secrete substances into the exterior environment.
Which that the following statements is INCORRECT?>Mucous membranes heat exits and also entrances come the body.>The cutaneous membrane is a dry membrane exposed to 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 come air, consists of a keratinized, stratified squamous epithelium called the epidermis, and an basic layer of connective tissue referred to as the dermis.
Which occasion must precede every others throughout tissue repair?>Clotting occurs in the damaged area.>Inflammation occurs near the affected cells.>Epithelia reproduce and also migrate to the damaged area.>Fibroblasts produce collagen that strengthens the area bordering the organization damage.
>Inflammation occurs near the influenced cells. Inflammation is the very first part that the organization repair. The inflammatory events set the phase for the organization repair process.
Connective tissues are made of various combinations of ground substance and fibers. Together you to compare slides the connective tissues, which would certainly most most likely be the strongest kind of connective tissue based on the composition of ground substance and also fibers?>connective tissues high in collagen fibers>connective tissue high in elastic fibers>connective tissue high in reticular fibers>connective tissue high in ground substance
>Connective tissues high in collagen fibers. Collagen is the toughest of the fibers. If you witnessed collagen in high amounts, the would suggest strength in the connective tissue.
