This feature of epithelial tissue is a thin extracellular layer comprised of a basal lamina and reticular lamina.
Epithelial tissue in which the cells appear to have layers, however, each cell is in contact with the basement membrane
What layer of tissue is identified by number 3?
What epithelial shape or arrangement is identified by the number 2?
Epithelial tissue:A. Conducts impulses to and from the central nervous systemB. Facilitates movement of body parts and substances within the bodyC. Forms a covering to protect the body from the outside worldD. Provides strength and holds organs together
This epithelial tissue appears to be multilayered. However, all cells are in contact with basal lamina?
What epithelial shape or arrangement is identified by the number 1?
What epithelial shape or arrangement is identified by the number 5?
How are endocrine and exocrine glands different from each other?>Exocrine glands are only unicellular in structure.>Exocrine glands secrete hormones.>Exocrine glands have specific target organs for their secretions.>Endocrine glands have no ducts.
After a heart attack, fibrosis occurs at the site of cardiac muscle cell death. This reduces the efficiency of the heart's pumping activity because __________.>the undamaged cardiac muscle cells become fatigued from the energy expended during the healing process>fibrous connective tissue is incapable of contracting>fibrosis produces new cardiac muscle cells that are not as strong as the mature ones that died>the initial death of some cardiac muscle cells triggers a chain reaction in which progressively more and more neighboring healthy cells die
What distinguishes the gland in A from the gland in B?>the use of a duct >the use of epithelial cells to produce products >the method of secretion >the direct secretion of products into the blood
You observe a uniform tissue under a microscope. There is no lumen. The material looks densely packed, but you do not observe many nuclei. It appears that there are strands of fibers running in parallel directions. What type of tissue are you looking at? >epithelial tissue >nervous tissue >muscle tissue >connective tissue
Connective tissues are made of different combinations of ground substance and fibers. As you compare slides of connective tissues, which would most likely be the strongest type of connective tissue based on the composition of ground substance and 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
Which of the following epithelial tissue types is NOT correctly matched to its function?>simple squamous epithelium; filtration>simple cuboidal epithelium; secretion>simple columnar epithelium with microvilli; absorption>stratified squamous epithelium; absorption
Injured cartilage might heal more quickly if a treatment were discovered that would __________.>prevent chondrocytes from dividing and thereby reducing the relative amount of matrix that is present in the cartilage>stimulate blood vessels to develop within cartilage>stimulate calcification of cartilage>All of the listed responses are correct.
Which property is most consistent in the majority of connective tissues? > large amounts of ground substance > large number of connective fibers > greater amount of extracellular matrix compared to cellular content > avasculartiy
Which of the following statements is INCORRECT?>Simple columnar epithelia are associated with absorption and secretion.>Stratified squamous epithelia are found in areas subjected to wear and tear.>Simple cuboidal epithelia are found in areas that stretch.>Simple squamous epithelia are associated with filtration and exchange.
Which event must precede all others during tissue repair?>Clotting occurs in the damaged area.>Inflammation occurs near the affected cells.>Epithelia reproduce and migrate to the damaged area.>Fibroblasts produce collagen that strengthens the area surrounding the tissue damage.
You observe a tissue under a microscope. There appears to be a lumen on one side of the tissue. Lining this lumen, the cells seem to have long, fingerlike projections. Beneath the projections, the cells seem to have the shape of shoeboxes and are packed tightly together. What type of tissue are you looking at? >stratified squamous epithelia >simple columnar epithelia >simple cuboidal epithelia >transitional epithelia
Under a microscope you observe a tissue that appears to have long fibers that appear striated. The nuclei are pushed off to the side of the fibers. The tissue looks very vascular. What type of tissue are you observing?>dense irregular connective tissue>dense regular connective tissue>skeletal muscle tissue>osseous tissue
