Question 1

Which of the following best describes the main structural difference between simple squamous and stratified squamous epithelium?

Accepted Answer

Simple squamous epithelium consists of a single layer of flat cells, while stratified squamous epithelium consists of multiple layers of flat cells.

Question 2

A biopsy from a patient's trachea reveals pseudostratified columnar ciliated epithelium with goblet cells. What is the primary function of this tissue in the trachea?

Accepted Answer

To secrete mucus and move particles out of the respiratory tract via ciliary action.

Question 3

Which connective tissue type is characterized by a matrix with thick, wavy collagen fibers arranged in parallel bundles and is found in tendons and ligaments?

Accepted Answer

Dense regular connective tissue

Question 4

A histological slide shows a tissue with chondrocytes in lacunae and a glassy, homogeneous matrix. This tissue is most likely:

Accepted Answer

Hyaline cartilage

Question 5

Which of the following best explains why stratified squamous epithelium is found in the esophagus?

Accepted Answer

It provides protection against abrasion from food particles.

Question 6

A patient has a genetic defect affecting the production of elastic fibers. Which tissue would be most directly affected?

Accepted Answer

Elastic connective tissue

Question 7

Which of the following cell types is most abundant in areolar (loose) connective tissue and is responsible for producing fibers?

Accepted Answer

Fibroblast

Question 8

A blood smear shows a cell with a multilobed nucleus and fine, pale granules in the cytoplasm. This cell is most likely a:

Accepted Answer

Neutrophil

Question 9

Which of the following best describes the difference between skeletal and cardiac muscle tissue?

Accepted Answer

Skeletal muscle fibers are multinucleated and peripherally located, while cardiac muscle cells have a single, centrally located nucleus.

Question 10

A tissue sample from the urinary bladder shows cells that appear cuboidal when relaxed and squamous when stretched. This tissue is:

Accepted Answer

Transitional epithelium

Question 11

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

Accepted Answer

Energy storage, insulation, and cushioning of organs

Question 12

Which of the following best describes the function of the endothelium lining blood vessels?

Accepted Answer

It provides a smooth surface to reduce friction for blood flow.

Question 13

A cross-section of an artery, vein, and nerve is observed under the microscope. Which structure is most likely to have the thickest wall relative to its lumen?

Accepted Answer

Artery

Question 14

Which of the following best explains why dense irregular connective tissue is found in the dermis of the skin?

Accepted Answer

It provides strength and resistance to forces from multiple directions.

Question 15

A patient with a deficiency in Schwann cells would most likely experience problems with which of the following?

Accepted Answer

Myelination of peripheral nerves

Question 16

Which of the following equations correctly represents the relationship between the thickness of a vessel wall ($t$), the radius of the lumen ($r$), and the pressure ($P$) according to the Law of Laplace for a cylindrical vessel?

Accepted Answer

$P = \frac{T}{r}$

Question 17

Which of the following best describes the function of reticular connective tissue in lymphoid organs?

Accepted Answer

It forms a supportive framework for cells involved in immune responses.

Question 18

A patient presents with a wound that is slow to heal and lacks the formation of granulation tissue. Which cell type is most likely deficient?

Accepted Answer

Fibroblast

Question 19

Which of the following best explains why bone tissue is able to resist compression and tension?

Accepted Answer

Its matrix contains both collagen fibers (for flexibility) and hydroxyapatite crystals (for strength).

Question 20

Which of the following is a distinguishing feature of nervous tissue observed in a smear preparation?

Accepted Answer

Presence of cell bodies with prominent nuclei and processes (axons and dendrites) extending from them.
