Question 1

Which of the following best describes the main function of dense regular connective tissue, as seen in tendons?

Accepted Answer

It resists tension and transmits force in one direction due to parallel collagen fibers.

Question 2

A patient suffers a tear in the tissue connecting muscle to bone. Which cell type is primarily responsible for producing the extracellular matrix in this tissue?

Accepted Answer

Fibroblasts

Question 3

Which connective tissue type is characterized by a matrix containing tightly packed collagen fibers arranged in an irregular pattern, allowing it to withstand tension from multiple directions?

Accepted Answer

Dense irregular connective tissue

Question 4

Which of the following equations correctly represents the composition of the extracellular matrix in connective tissue?

Accepted Answer

$$Extracellular\ Matrix = Ground\ substance + Fibers$$

Question 5

A biopsy reveals tissue with chondrocytes in lacunae, a glassy matrix, and no blood vessels. Which tissue is this most likely to be?

Accepted Answer

Hyaline cartilage

Question 6

Which connective tissue is specialized for fat storage and insulation, and what is the primary cell type found in this tissue?

Accepted Answer

Adipose tissue; Adipocytes

Question 7

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

Accepted Answer

Cartilage is avascular and relies on diffusion from the perichondrium for nutrients.

Question 8

Which connective tissue type forms the internal framework (stroma) of lymph nodes and the spleen?

Accepted Answer

Reticular connective tissue

Question 9

A slide shows concentric rings (lamellae) around a central canal. Which tissue is this, and what is the functional unit called?

Accepted Answer

Bone; Osteon

Question 10

Which of the following is a unique feature of blood as a connective tissue compared to other connective tissues?

Accepted Answer

It has a fluid matrix called plasma.

Question 11

Which fiber type is most responsible for the high tensile strength of tendons?

Accepted Answer

Collagen fibers

Question 12

A patient with a genetic defect in elastin production would most likely have problems with which tissue function?

Accepted Answer

Stretch and recoil of tissues such as arteries

Question 13

Which cell type is responsible for maintaining the bone matrix?

Accepted Answer

Osteocytes

Question 14

Which connective tissue type is most likely to be found in the walls of large arteries, and what property does it provide?

Accepted Answer

Elastic connective tissue; Stretch and recoil

Question 15

Which of the following best describes the ground substance in connective tissue?

Accepted Answer

An unstructured material that fills the space between cells and fibers

Question 16

Which connective tissue type is best suited for resisting compressive shock in intervertebral discs?

Accepted Answer

Fibrocartilage

Question 17

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

Accepted Answer

Production of antibodies for immune defense

Question 18

Which of the following best explains why areolar connective tissue is found beneath most epithelial tissues?

Accepted Answer

It acts as a reservoir for water and salts, supporting epithelial cell survival.

Question 19

Which of the following cell types is NOT correctly matched with its connective tissue?

Accepted Answer

Fibroblast – Blood

Question 20

A tissue sample contains a fluid matrix, erythrocytes, leukocytes, and platelets. Which tissue is this, and what is its primary function?

Accepted Answer

Blood; Transport of gases, nutrients, and wastes
