Question 1

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

Accepted Answer

They prevent fluids and solutes from passing between cells, isolating enzymes and wastes to the lumen.

Question 2

A patient presents with a skin injury. Which type of epithelial tissue is most likely to provide the greatest protection against mechanical abrasion?

Accepted Answer

Stratified squamous epithelium (keratinized)

Question 3

Which connective tissue fiber type is most abundant in tendons and ligaments, providing strength and resisting force in one direction?

Accepted Answer

Collagen fibers

Question 4

Which of the following best explains why cartilage heals poorly after injury?

Accepted Answer

Chondrocytes produce antiangiogenesis factor, making cartilage avascular.

Question 5

A newborn is found to have abundant brown adipose tissue. What is the primary function of this tissue in infants?

Accepted Answer

To generate heat by breaking down fat, aiding temperature homeostasis

Question 6

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

Accepted Answer

Exocrine glands release secretions into ducts that deliver to epithelial surfaces, while endocrine glands release hormones directly into the blood.

Question 7

Which of the following cell types in connective tissue proper is responsible for secreting the ground substance and protein fibers of the matrix?

Accepted Answer

Fibroblasts

Question 8

A biopsy of a patient’s liver reveals a network of thin, branching fibers supporting functional cells. Which fiber type is most likely present?

Accepted Answer

Reticular fibers

Question 9

Which membrane lines body cavities that are open to the exterior and consists of an epithelium supported by connective tissue called the lamina propria?

Accepted Answer

Mucous membrane

Question 10

During the inflammatory response, which cell releases histamine, heparin, and prostaglandins to initiate inflammation?

Accepted Answer

Mast cells

Question 11

Which of the following best describes the process of holocrine secretion?

Accepted Answer

Product is released by cells bursting, killing the gland cells, which are replaced by stem cells.

Question 12

Which of the following equations correctly represents the proportion of extracellular fluid in the body?

Accepted Answer

$$\frac{1}{3} of $$body fluid is extracellular, $$\frac{2}{3} is $$intracellular$

Question 13

Which type of connective tissue proper is most likely to be found in the deep layer of the skin, providing resistance to forces in multiple directions?

Accepted Answer

Dense irregular connective tissue

Question 14

A patient with a torn tendon is expected to have slow healing. Which property of dense regular connective tissue explains this?

Accepted Answer

It contains tightly packed collagen fibers in parallel, but blood vessels are not plentiful.

Question 15

Which of the following best describes the functional unit of compact bone?

Accepted Answer

Osteon

Question 16

Which type of muscle tissue is found in the walls of hollow organs, is non-striated, and under involuntary control?

Accepted Answer

Smooth muscle

Question 17

Which of the following cell types in nervous tissue is responsible for conducting electrical impulses and processing information?

Accepted Answer

Neurons

Question 18

A patient develops an abscess after injury. Which process led to the formation of pus trapped in the tissue?

Accepted Answer

Necrosis caused by enzymes from lysosomes destroying injured cells and tissues

Question 19

Which of the following best explains why aging increases the risk of cancer and cardiovascular disease?

Accepted Answer

Aging decreases tissue repair efficiency, thins epithelia and connective tissues, and increases cell mutation rates.

Question 20

Which of the following best describes the difference between the visceral and parietal layers of serous membranes?

Accepted Answer

The visceral layer covers the organs, while the parietal layer lines the cavity walls.
