Question 3

Which of the following statements about epithelial tissue is correct?

Accepted Answer

Epithelial tissue is supported by a connective tissue reticular lamina

Question 4

A gland that releases its product by exocytosis without damaging the cell is classified as which type of gland?

Accepted Answer

Question 5

Which connective tissue fiber type is most responsible for providing high tensile strength to tendons?

Accepted Answer

Collagen fibers

Question 6

A patient suffers a deep cut that damages both the epidermis and underlying connective tissue. Which sequence best describes the steps of tissue repair?

Accepted Answer

Inflammation, organization, regeneration

Question 7

Which of the following best explains why cartilage heals more slowly than bone?

Accepted Answer

Cartilage is avascular, while bone is highly vascularized

Question 8

Which of the following is a correct pairing of connective tissue cell type and its mature form?

Accepted Answer

Chondroblast – chondrocyte

Question 9

A tissue sample from the urinary bladder shows several layers of cells, with basal cells cuboidal and surface cells dome-shaped. What is the function of this tissue?

Accepted Answer

Stretching to permit distension

Question 10

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

Question 14

Which of the following is a function of areolar connective tissue?

Accepted Answer

Binding and supporting other tissues

Question 15

A patient presents with a tumor in the pancreas that is producing excessive insulin. Which type of tissue is most likely responsible for this secretion?

Accepted Answer

Glandular epithelial tissue

Accepted Answer

Ground substance

Question 18

Which of the following best describes the function of intercalated discs in cardiac muscle tissue?
