Question 1

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

Accepted Answer

They prevent the passage of water and solutes between cells from the lumen to underlying tissues.

Question 2

A patient suffers a severe burn that destroys the epidermis. Which tissue type is primarily affected, and what is a key characteristic of this tissue?

Accepted Answer

Epithelial tissue; avascular and capable of rapid regeneration.

Question 3

Which of the following best explains why cartilage injuries heal slowly compared to bone injuries?

Accepted Answer

Cartilage lacks a blood supply, making nutrient delivery and waste removal less efficient.

Question 4

A gland that releases its product by exocytosis without losing any cytoplasm is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 5

Which connective tissue cell type is primarily responsible for producing the protein fibers found in connective tissue proper?

Accepted Answer

Fibroblasts

Question 6

A biopsy of a patient’s trachea reveals a single layer of ciliated cells that appear stratified. Which type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 7

Which of the following best describes the function of serous membranes?

Accepted Answer

They line internal cavities, reduce friction, and secrete serous fluid.

Question 8

A patient with a genetic defect in collagen synthesis would most likely experience problems with which tissue function?

Accepted Answer

Providing tensile strength to tendons and ligaments

Question 9

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

Accepted Answer

Adipocyte – stores triglycerides

Question 10

Which of the following best explains why the cutaneous membrane is considered an effective barrier?

Accepted Answer

It is made of keratinized stratified squamous epithelium and dense connective tissue.

Question 11

A patient is diagnosed with a tumor in a gland that releases hormones directly into the bloodstream. Which type of gland is affected?

Accepted Answer

Endocrine gland

Question 12

Which of the following best describes the role of neuroglia in nervous tissue?

Accepted Answer

They provide nutrients, maintain structure, and perform phagocytosis.

Question 13

A patient with chronic inflammation in the joints is likely experiencing increased activity of which connective tissue cell type?

Accepted Answer

Mast cells

Question 14

Which of the following best explains why skeletal muscle tissue has limited ability to repair after injury?

Accepted Answer

Skeletal muscle fibers are multinucleate and do not divide easily.

Question 15

Which of the following is a correct sequence of events during tissue response to injury?

Accepted Answer

Inflammation is triggered by mast cell activation, followed by regeneration to restore function.

Question 16

Which of the following best describes the difference between simple and stratified epithelia?

Accepted Answer

Simple epithelia consist of a single layer of cells; stratified epithelia have several layers.

Question 17

A patient with a deficiency in elastic fibers would most likely experience which of the following symptoms?

Accepted Answer

Reduced ability of tissues to return to their original shape after stretching

Question 18

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

Accepted Answer

Aging slows tissue repair and increases the accumulation of damage, making cells more susceptible to carcinogens.

Question 19

Which of the following equations best represents the relationship between the components of the connective tissue matrix?

Accepted Answer

$$Matrix = Protein\ Fibers + Ground\ Substance$$

Question 20

A patient presents with swelling and redness after an injury. Which chemical released by mast cells is primarily responsible for stimulating inflammation?

Accepted Answer

Histamine
