$$\text{Extracellular Matrix} = \text{Protein Fibers} + \text{Ground Substance}$$

Question 1

Which of the following best describes the primary function of fibroblasts in connective tissue?

Accepted Answer

They produce and maintain the extracellular matrix, including collagen and elastic fibers.

Question 2

A patient presents with a genetic disorder affecting the production of collagen fibers. Which tissue type would be most directly affected?

Accepted Answer

Dense regular connective tissue

Question 3

Which of the following is a correct sequence for the classification of connective tissue from the most undifferentiated to the most specialized?

Accepted Answer

Mesenchyme → Connective tissue proper → Supporting connective tissue → Blood

Question 4

Which connective tissue type is found in the papillary layer of the dermis and is characterized by a loose arrangement of collagen and elastic fibers?

Accepted Answer

Areolar connective tissue

Question 5

A biopsy from the umbilical cord reveals a tissue with abundant ground substance, immature protein fibers, and mesenchymal cells. What is this tissue?

Accepted Answer

Mucous connective tissue (Wharton's jelly)

Question 6

Which of the following best explains why tendons are slow to heal after injury?

Accepted Answer

They contain few blood vessels and are composed mainly of dense regular connective tissue.

Question 7

Which cell type is responsible for the immune defense in connective tissue by engulfing pathogens?

Accepted Answer

Macrophage

Question 8

A histological slide shows large, empty-looking cells with nuclei pushed to the periphery and very little extracellular matrix. Which tissue is this?

Accepted Answer

Adipose tissue

Question 9

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

Accepted Answer

$$	ext{Extracellular Matrix} = 	ext{Protein Fibers} + 	ext{Ground Substance}$$

Question 10

Which connective tissue type is specialized for resisting tension in one direction and is found in tendons?

Accepted Answer

Dense regular connective tissue

Question 11

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 12

Which of the following best describes the main function of reticular fibers in connective tissue?

Accepted Answer

They form a supportive framework for soft organs such as the spleen and lymph nodes.

Question 13

Which of the following tissues is classified as a fluid connective tissue?

Accepted Answer

Blood

Question 14

A slide of compact bone shows concentric rings around a central canal. What is the name of this structural unit?

Accepted Answer

Osteon

Question 15

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

Accepted Answer

Cartilage is avascular, while bone is highly vascularized.

Question 16

Which connective tissue type is found in the reticular layer of the dermis and is characterized by irregularly arranged collagen fibers?

Accepted Answer

Dense irregular connective tissue

Question 17

Which of the following cells is most likely to increase in number during an infection and is visible in a blood smear?

Accepted Answer

Lymphocyte

Question 18

Which of the following best describes the function of canaliculi in compact bone?

Accepted Answer

They allow for the exchange of nutrients and waste between osteocytes.

Question 19

A patient with a mutation affecting mesenchymal cells would most likely have defects in which of the following?

Accepted Answer

Development of all connective tissues

Question 20

Which of the following best describes the main difference between hyaline cartilage and fibrocartilage?

Accepted Answer

Fibrocartilage contains dense bundles of collagen fibers, making it stronger and more resistant to compression.
