Question 4

Which connective tissue type contains a dense arrangement of collagen fibers and is found in tendons and ligaments?

Accepted Answer

Dense regular connective tissue

Question 5

A patient presents with a skin injury that exposes underlying tissue. Which epithelial tissue provides the best protection against abrasion in this scenario?

Accepted Answer

Stratified squamous epithelium, keratinized

Question 6

Which connective tissue type is specialized for energy storage and insulation?

Accepted Answer

Adipose connective tissue

Question 7

Which of the following best describes the function of microvilli on simple columnar epithelial cells in the small intestine?

Accepted Answer

Increase surface area for absorption

Question 8

A histological slide shows a tissue with lacunae and a glassy extracellular matrix. Which tissue is this, and what is its primary function?

Accepted Answer

Hyaline cartilage; provides flexible support and reduces friction

Question 9

Which equation correctly expresses the relationship between the number of cell layers ($$n) $$and the degree of protection ($$P) $$provided by stratified epithelium?

Accepted Answer

$$P = k 	imes n$$

Question 10

Which tissue type is found lining the urinary bladder and is specialized to stretch and recoil?

Accepted Answer

Transitional epithelium

Question 11

A biopsy from the esophagus reveals multiple layers of flat cells. What is the most likely tissue type and its function?

Accepted Answer

Stratified squamous epithelium, nonkeratinized; protection against abrasion

Question 12

Which connective tissue type forms the stroma of lymph nodes and spleen, providing a supportive framework for immune cells?

Accepted Answer

Reticular connective tissue

Question 13

Which of the following is a key structural difference between simple and stratified epithelial tissues?

Accepted Answer

Simple epithelium has one layer of cells; stratified has multiple layers

Question 14

Which connective tissue type is found in the walls of large arteries and is specialized for elasticity?

Accepted Answer

Elastic connective tissue

Question 15

A patient with a thyroid disorder has abnormal hormone secretion. Which epithelial tissue is most likely affected?

Accepted Answer

Simple cuboidal epithelium

Question 16

Which of the following best explains why stratified squamous epithelium is found in areas subject to friction, such as the skin and esophagus?

Accepted Answer

It provides multiple layers for protection against abrasion

Question 17

Which tissue type contains chondrocytes in lacunae and is found in the intervertebral discs?

Accepted Answer

Fibrocartilage

Question 18

Which equation best represents the relationship between the number of microvilli ($$m) $$and the total absorptive surface area ($$A) in $$the small intestine?

Accepted Answer

$$A = k 	imes m$$

Question 19

Which connective tissue type is found in the dermis of the skin and provides resistance to multidirectional stress?

Accepted Answer

Dense irregular connective tissue

Question 20

A histological section of bone shows concentric rings around a central canal. What is the name of this structural unit, and what is its function?

Accepted Answer

Osteon; provides structural support and houses blood vessels
