Question

4 How do pseudostratified ciliated columnar epithelium and transitional epithelium differ from other types of epithelia? 5 TruelFalse: Mark the following statements concerning connective tissue proper and cartilage as true (T) or false (F). If the statement is false, correct it to make it a true statement. Adipocytes contain a large lipid droplet in their cytoplasm. The primary element in dense regular collagenous connective tissue is ground substance Bundles of collagen fibers are arranged parallel to one another in dense irregular collagenous connective tissue. Loose connective tissue contains all three protein fiber types Fibrocartilage has a smooth, glassy appearance due to a large amount of ground substance and few visible protein fibers. 6 Which of the following best characterizes the extracellular matrix (ECM) of bone tissue? a. Bone tissue ECM consists of only calcium hydroxyapatite crystals b. Bone tissue ECM consists of calcium hydroxyapatite crystals and collagen fibers. C. Bone tissue ECM consists of only collagen fibers. d. Bone tissue ECM consists of collagen, elastic, and reticular fibers. 7 Circle all that apply. Which of the following characteristics apply to skeletal muscle tissue? a. Striated. b. Nonstriated. c. Multinucleate. d. Uninucleate e Contains intercalated discs. f Voluntary g Involuntary h. Autorhythmic

Explanation / Answer

Q 4 Defference between Peudostratified Ciliated Columnar Epithelium, Transitional Epithelium and Simple squamous epithelium.

Peudostratified

Transitional

Simple Squamous

Simple Cuboidal

Description

Not a true stratified tissue cell are attached to basement membrane

Appearance is variable, shape of cells in apical layer ranges from squamous

Single layer of flat cells, centrally located nucleus

Single layer of cube-shaped cells, centrally located nucleus

Location

Upper respiratory tract, epididymis

Lines urinary bladder and portion of ureters and urethra

Lines heart, blood vessels, lymphatic vessel, air sacs of lungs

Surface of ovary, lens of the eye kidney tubules

Functions

Secretion and movement of mucus by ciliary action

Permits distension

Filtration, diffusion, osmosis and secretion in serous membrane

Secretion and absorption

Q 5 Answer-

False- Adipocytes contain a large lipid droplets in their cytoplasm.

True- cytoplasm in adipocytes is displaced by large lipid droplet.

True- The primary element in dense in regular college nous connective tissue is ground substance.

False- Bundles of collagen fibers are arranged parallel to one another in dense irregular college nous connective tissue.

True- Dense irregular connective tissue has fibers that are not arranged in parallel bundles as in dense regular connective tissue.

True-Loose connective tissue contains all three protein fiber type.

False- Fibrocartilage has a smooth glassy appearance due to a large amount of ground substance and few visible protein fibers.

True- Fibrocartilage has a smooth glassy appearance due to a large amount of ground substance and lake of visible protein fibers.

Q 6 Answer-

B- Bone tissue ECM consists of hydoxyapatite crystals and collagen fibers.

Q7 Answer-

a. Striated

c. Multinucleated

e. Contains intercalated discs

f. Voluntary
