Honors Physio chapter 4

supports and protects; insulates against heat loss; reserve source of fuel

adipose tissue
- consists of adipocytes
- cells store triglycerides
- nucleus and cytoplasm are peripherally located

supports and protects; stores calcium

bone (osseous) tissue
- osteons; lamellae, lacunae, osteocytes, canaliculi, haversian canals

provides tensile strength with the ability to absorb compressive shock

fibrocartilage
- chondrocytes scattered among bundles of collagen fibers

skeletal muscle

- flexible muscle fibers
- long, cylindrical, striated

forms tendons and ligaments

dense regular
- consists of collagen fibers arranged in bundles
- fibroblasts present between bundles

which cells are commonly found wedged between simple columnar epithelial cells?

goblet cells

ciliated simple columnar epithelium

heart muscle cells would tend to separate without ___

intercalated discs

connective tissue extracellular matrix is composed of ___

fibers and ground substance

which statement best describes connective tissue?

usually contains a large amount of matrix

which of the following would be of most importance to goblet cells and glandular epithelium?

golgi apparatus

select the correct statement regarding tissue repai

inflammation causes capillaries to dilate and become permeable

a many-layered epithelium with cuboidal basal cells and flat cells at its surface would be classified as ___

stratified squamous

which of the following is true about the mode of secretion of exocrine glands?

merocrine glands are not altered by the secretory process

what tissue has lacunae, calcium salts, and blood vessels?

bone (osseous) tissue

select the correct statement regarding epithelia

stratified epithelia are present where protection from abrasion is important

what are the three main components of connective tissue?

ground substance, fibers, and cells

select the correct statement regarding adipose tissue

its primary function is nutrient storage

your instructor gives you an unknown organ for you to examine and identify through microscopy
what should you do first with the sample?

fix it with preservative

which of the following is true about epithelia?

endothelium provides a slick surface lining all hollow cardiovascular organs

select the correct statement regarding the stem cells of connective tissue

the shape of the external ear is maintained by ___

elastic cartialge

how is hyaline cartilage different from elastic cartilage or fibrocartilage?

fibers are not normally visible

which of the following statements is true of connective tissue?

collagen fibers provide high tensile strength

which is true concerning muscle tissue?

highly cellular and well vascularized

skin, lung, and blood vessel walls have which tissue characteristic in common?

elastic fibers

___ epithelium appears to have two or three layers of cells, but all the cells are in contact with the basement membrane

pseudostratified columnar

generally speaking, connective tissues are largely non-living extracellular matrix
which of the following is an exception?

adipose

inability to absorb digested nutrients and secrete mucus might indicate a disorder in which epithelial tissue?

simple columnar

acts as "spot welds, holds cells together with cadherins, stabilizes epidermis

desmosomes

epithelial tissues are classified based on

a) the arrangement of cells in layers
b) the shapes of the cells in the most superficial layer

found in urinary bladder, allows stretching

transitional epithelium

protects underlying tissues; named for numbers of layers + shape of top layer of cells

stratified squamous epithelium

protects underlying tissues; named for numbers of layers + shape of top layer of cell

stratified squamous epithelium

which tissue forms coverings, linings, and glands?

epithelial

contractile tissue; cells called fibers; 2 forms striated; 2 under involuntary control

muscle control

secretes and absorbs materials in the GI tract; cells taller than they are wide

conciliated simple columnar

lines Fallopian (uterine) tubes, some parts of upper respiratory tract

ciliated simple columnar epithelium

which of the following is true of glandular epithelia?

their primary function is secretion

found in much of upper respiratory tract, secretes and moves mucous

pseudostratified columnar epithelium

a pathologist examines a thin slice of tissue with a microscope and notes numerous cells packed tightly together. no intercellular space or blood vessel is noted between cells, but the cells have polarity. one side of the cells opens into a cavity, and the other is attached to a thin layer of extracellular material. several of the cells are in some stage of mitosis.
which primary tissue type does the pathologist see?

epithelial

lat sheets of flexible tissue found covering or lining large portions of the body are ___

called membrane

each of the following cell junctions links cells to each other EXCEPT:

hemidesmosomes

which modification of columnar epithelium is correctly described?

microvilli; increase surface area for absorption

a papanicolaou smear

examines nonkeratanized stratified squamous epithelium

keratin is seen in tissues that

resist friction
