Question 2

A patient suffers a tendon injury. Which connective tissue type is most likely affected, and what is its primary structural feature?

Accepted Answer

Dense regular connective tissue; parallel bundles of collagen fibers

Question 3

Which connective tissue type provides nutritional support to neighboring tissues by carrying blood vessels and capillaries?

Accepted Answer

Areolar (loose) connective tissue

Question 4

Which of the following best describes the function of reticular connective tissue?

Accepted Answer

Forms a supportive framework for lymphoid organs

Question 5

Elastic connective tissue is found in the walls of large arteries. What property does it confer to these structures?

Accepted Answer

Ability to stretch and recoil

Question 6

Which supporting connective tissue type is avascular and relies on diffusion through its matrix for nutrient supply?

Accepted Answer

Hyaline cartilage

Question 7

A histological slide shows cells embedded in lacunae within a glassy matrix. Which tissue is this, and what is its main function?

Accepted Answer

Hyaline cartilage; provides smooth surfaces for joint movement

Question 8

Which connective tissue type is characterized by concentric rings (osteons) and a highly vascularized structure?

Accepted Answer

Compact bone

Question 9

A patient with a ruptured intervertebral disc is most likely to have damage to which type of connective tissue?

Accepted Answer

Fibrocartilage

Question 10

Which equation best represents the relationship between the density of collagen fibers ($$D) $$and the resistance to stretching ($$R) in $$dense connective tissue?

Accepted Answer

$$R \propto D$$

Question 11

Which connective tissue type is most specialized for energy storage, insulation, and cushioning of organs?

Accepted Answer

Adipose tissue

Question 12

Which of the following is a common histological origin for all connective tissues?

Accepted Answer

Mesenchyme

Question 13

Which connective tissue type is most likely to be found in the lymph nodes, providing a supportive network for immune cells?

Accepted Answer

Reticular connective tissue

Question 14

A biopsy reveals a tissue with abundant elastic fibers and chondrocytes in lacunae. Which tissue is this, and where is it commonly found?

Accepted Answer

Elastic cartilage; external ear

Question 15

Which connective tissue type is best suited to resist compressive forces and is found in intervertebral discs?

Accepted Answer

Fibrocartilage

Question 16

Which of the following best explains why cartilage heals more slowly than bone?

Accepted Answer

Cartilage is avascular, while bone is highly vascularized

Question 17

Which connective tissue type is most likely to be found surrounding organs, providing both support and flexibility?

Accepted Answer

Areolar (loose) connective tissue

Question 18

Which of the following equations best describes the relationship between the number of elastic fibers ($$E) $$and the tissue's ability to recoil ($$A) in $$elastic connective tissue?

Accepted Answer

$$A \propto E$$

Question 19

Which connective tissue type is most likely to be found in the trachea, providing structural support and maintaining an open airway?

Accepted Answer

Hyaline cartilage

Question 20

Which of the following best describes the arrangement of collagen fibers in dense regular connective tissue, and why is this arrangement functionally important?

Accepted Answer

Parallel bundles; transmits force efficiently in one direction
