Q: Which equation best represents the relationship between the number of cell layers ($$n) $$and the function of epithelial tissue?

$$\text{Protection} \propto n$$

Question 1

Which of the following best describes the process of preparing animal tissue for microscopic viewing?

Accepted Answer

Fixing, slicing thinly, and staining with dyes that bind to different cell parts.

Question 2

A patient suffers a skin abrasion. Which tissue type is most likely to regenerate efficiently and why?

Accepted Answer

Keratinized stratified squamous epithelium, because it is highly mitotic and adapted to withstand abrasion.

Question 3

Which of the following is a key structural feature that distinguishes epithelial tissue from connective tissue?

Accepted Answer

Epithelial tissue is avascular and supported by a basement membrane, while connective tissue is vascular and contains abundant extracellular matrix.

Question 4

Which of the following best describes the function and location of simple squamous epithelium?

Accepted Answer

Filtration and exchange of substances; found in the lining of blood vessels and alveoli of lungs.

Question 5

A multicellular exocrine gland with a branched duct and secretory units that release their products by cell rupture is classified as:

Accepted Answer

Compound holocrine gland

Question 6

Which connective tissue type is most likely to be found forming the internal framework of lymph nodes, spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 7

A tendon is composed primarily of which type of connective tissue, and what is its main structural feature?

Accepted Answer

Dense regular connective tissue; closely packed bundles of collagen fibers running in the same direction.

Question 8

Which of the following statements about cartilage is correct?

Accepted Answer

Cartilage is avascular and heals slowly due to lack of blood supply.

Question 9

Which equation best represents the relationship between the number of cell layers ($$n) $$and the function of epithelial tissue?

Accepted Answer

$$	ext{Protection} \propto n$$

Question 10

A patient with a wound in the dermis will experience which sequence of tissue repair?

Accepted Answer

Inflammation, organization (granulation tissue formation), regeneration and fibrosis.

Question 11

Which of the following best explains why the skin is composed of keratinized stratified squamous epithelium?

Accepted Answer

It provides multiple layers for protection against abrasion and contains keratin for waterproofing.

Question 12

Which of the following is true regarding the embryonic origin of tissues?

Accepted Answer

Mesoderm gives rise to connective, muscle, and some epithelial tissues.

Question 13

Which of the following equations best represents the relationship between the rate of tissue regeneration ($$R) $$and vascularization ($$V) $$for connective tissues?

Accepted Answer

$$R \propto V$$

Question 14

Which membrane is classified as a dry membrane and consists of keratinized stratified squamous epithelium attached to dense irregular connective tissue?

Accepted Answer

Cutaneous membrane

Question 15

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands are ductless and secrete hormones directly into the blood; exocrine glands have ducts and secrete onto surfaces or into cavities.

Question 16

Which of the following muscle tissue types is involuntary, unstriated, and found in the walls of hollow organs?

Accepted Answer

Smooth muscle

Question 17

Which cell type is responsible for producing the organic portion of bone matrix?

Accepted Answer

Osteoblasts

Question 18

Which of the following best describes the function of neurons in nervous tissue?

Accepted Answer

Neurons respond to stimuli and generate/conduct electrical impulses.

Question 19

A patient is diagnosed with carcinoma. Based on tissue origin, which primary tissue type is most likely involved?

Accepted Answer

Epithelial tissue

Question 20

Which of the following equations best represents the relationship between the amount of extracellular matrix ($$M) $$and nutrient storage location in bone and adipose tissue?

Accepted Answer

Bone: $$M \gg$$ cell volume, nutrients stored in matrix; Adipose: $$M \ll$$ cell volume, nutrients stored in cells.
