Question 7

Which of the following structures is found in the dermis but not in the epidermis?

Accepted Answer

Dermal papillae

Question 8

A tissue sample from the trachea shows ciliated cells and goblet cells arranged in a way that appears to be stratified, but all cells touch the basement membrane. What is the correct classification of this epithelium?

Accepted Answer

Pseudostratified columnar epithelium

Question 9

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

Accepted Answer

They allow for rapid communication and synchronized contraction between cardiac muscle cells.

Question 10

A patient presents with a skin wound that is slow to heal. Upon examination, it is found that the tissue has a low density of blood vessels. Which layer is most likely involved?

Accepted Answer

Epidermis

Question 11

Which of the following is a characteristic feature of dense regular connective tissue?

Accepted Answer

Parallel bundles of collagen fibers

Question 12

A histology slide shows a tissue with multiple layers of cells, with the apical layer consisting of flat, scale-like cells. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 13

Which of the following best explains why the epidermis is considered avascular?

Accepted Answer

It lacks blood vessels and receives nutrients by diffusion from the dermis.

Question 14

A tissue sample from the urinary bladder shows cells that appear cuboidal when relaxed and squamous when stretched. What is the name of this epithelium?

Accepted Answer

Transitional epithelium

Question 15

Which of the following is NOT a function of adipose tissue?

Accepted Answer

Chondrocyte

Question 17

Which of the following best describes the function of the basement membrane in epithelial tissues?
