Question 1

Which of the following best describes the primary function of tight junctions in epithelial tissue?

Accepted Answer

They prevent the passage of substances between adjacent cells, forming a selective barrier.

Question 2

A patient presents with a skin disorder where the epidermis easily separates from the underlying dermis, leading to blister formation. Which cell junction is most likely defective?

Accepted Answer

Hemidesmosome

Question 3

Which type of epithelial tissue is best suited for rapid diffusion and filtration, and where is it commonly found?

Accepted Answer

Simple squamous epithelium; alveoli of the lungs

Question 4

Which of the following statements about epithelial cells is TRUE?

Accepted Answer

They attach to connective tissue via the basement membrane.

Question 5

A gland that releases its secretion by exocytosis without losing any part of the cell is classified as which type?

Accepted Answer

Merocrine

Question 6

Which connective tissue subtype is most abundant in the dermis and provides strength in multiple directions due to its irregular fiber arrangement?

Accepted Answer

Dense irregular connective tissue

Question 7

Which of the following is a correct pairing of cell type and its function in connective tissue?

Accepted Answer

Fibroblast – synthesizes collagen fibers

Question 8

A tissue sample from the urinary bladder shows cells that change shape from cuboidal to squamous when stretched. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 9

Which muscle tissue type is characterized by striations and intercalated discs, and is responsible for involuntary contractions?

Accepted Answer

Cardiac muscle

Question 10

Which membrane lines body cavities that do NOT open to the exterior and consists of a simple squamous epithelium over areolar connective tissue?

Accepted Answer

Serous membrane

Question 11

Which of the following equations correctly represents the relationship between tissue repair rate ($R$), mitotic ability ($M$), and tissue type ($T$), assuming $R$ is directly proportional to $M$ and varies by $T$?

Accepted Answer

$R \propto M$

Question 12

Which connective tissue subtype contains chondrocytes in lacunae, is avascular, and provides flexible support to structures like the epiglottis and auricle of the ear?

Accepted Answer

Elastic cartilage

Question 13

Which of the following best explains why epithelial tissue is highly regenerative compared to muscle and nervous tissue?

Accepted Answer

Epithelial cells have a high mitotic rate.

Question 14

A multicellular gland with a branched duct and acinar secretory portions is classified structurally as:

Accepted Answer

Compound acinar

Question 15

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

Accepted Answer

Secretion of digestive enzymes

Question 16

Which equation best represents the total number of cell layers ($L$) in a stratified epithelium, given that $L > 1$?

Accepted Answer

$L > 1$

Question 17

Which type of cell junction allows direct passage of ions and small molecules between adjacent cells, facilitating rapid communication?

Accepted Answer

Gap junction

Question 18

Which of the following best describes the role of the basement membrane in epithelial tissue?

Accepted Answer

It anchors epithelial cells to underlying connective tissue.

Question 19

Which of the following is TRUE regarding the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands release hormones directly into the blood; exocrine glands release secretions through ducts to the surface.

Question 20

Which of the following cell types is responsible for supporting and protecting neurons in nervous tissue?

Accepted Answer

Neuroglia
