Epithelium and Connective Tissue Review Flashcards
The formation of scar tissue following surgery or wounding is largely due to
Fibroblasts
Aponeuroses are composed of which type of connective tissue proper?
Dense regular connective tissue
Given the structure of a cilium, you would not expect to find cilia on which of these types of epithelial tissue?
Stratified squamous keratinized epithelium
A free surface specialization only found on hair cells of the inner ear and in epididymis of male reproductive system is:
Stereocilia
Where is stratified cuboidal epithelium found?
Excretory ducts of salivary and sweat glands.
Which is the function of hemidesmosomes?
Attach epithelial cells to basement membrane
The connective tissue that is found in a tendon is:
dense and regular
What is the most abundant protein in the human body?
Collagen
What is the name for the unicellular glands that secrete lubricating mucus?
Goblet cells
What do these cell types have in common: Microglia, osteoclasts, and Kupffer cells?
They are part of the mononuclear phagocyte system.
Which type of secretion do sebaceous glands have?
Holocrine
Which of these is not a function of macrophages?
Hemopoiesis
What is the function of the adherent junctions?
Strengthen adjacent tight junctions
What is the function of mucoid connective tissue?
Protection of blood vessels in the umbilical cord.
What are the two main components of extracellular matrix?
Ground Substance and Protein Fibers
The connective tissue cell whose role is to release stored granules to mediate an inflammatory response is the
Mast cell
Connective tissue forms the ________________of many organs.
Stroma
Compound Acinar is found in
Exocrine cells of the pancreas
Simple branched acinar is found in
Cutaneous sebaceous glands
Compound tubuloacinar is found in
Salivary Glands
Simple tubular is found in
Mucous glands of colon
Coiled tubular is found in
Sweat glands
The 9 + 2 axoneme of a cilium is very similar to the flagellum that is found in
Sperm cells
Reticular fibers are made of type III collagen. They function as a supportive stroma in which organs/glands?
Lymphoid organs
Hematopoietic organs
Endocrine glands
The dermis of the skin contains which type of connective tissue proper?
Dense irregular connective tissue
One type of GAG is chondroitin sulfate, which functions in space-filling, cushioning, and lubrication. One tissue where this molecule is found is
Cartilage
The type of gland which has no duct is the
Endocrine gland
One major function of connective tissue proper is to physically support and connect other tissues. A second major function is to
Maintain water as interstitial fluid for nutrient and metabolite diffusion, using hydrostatic and osmotic pressure.
One of the features of urothelium is that
It has a layer of umbrella cells.
It lines much of the urinary tract.
It is distensible
Collagen synthesis is a product of which of the following cells?
Fibroblasts
The brush border is formed by
Microvilli of intestinal epithelial cells
The type of connective tissue proper immediately adjacent to the epithelium (e.g. the papillary layer of skin) is most likely to be
Loose connective tissue
Edema is the excessive accumulation of interstitial fluid in connective tissue. Where does this fluid come from before it accumulates in the connective tissue?
Blood
Mesenchyme is an embryonic tissue composed of undifferentiated cells that have the ability to produce connective tissue proper, bone, cartilage, and muscle, among others. From which major embryonic tissue is mesenchyme derived?
Mesoderm
Endothelium is a type of epithelial tissue that lines the inner surface of blood vessels, and regulates passage of substances into the tissue below. Endothelium is composed of cells with what type of arrangement and shape?
Simple squamous
The largest and most unique GAG (glycoaminoglycan) is:
Hyaluronic acid (hyaluronan)
The intercellular seal of tight junctions ensures that molecules crossing an epithelium in either direction do so by going through the cells rather than between them. This path between the cells is called the
Paracellular pathway
Which of the following types of epithelia has all cells attached to the basal lamina, but not all cells reach the free surface?
Pseudostratified columnar
Loss of the microvilli of absorptive cells in the small intestine may be caused by
Gluten-sensitive enteropathy
