Question 1

Which of the following is NOT a major function of connective tissue in the human body?

Accepted Answer

Generating electrical impulses for communication

Question 2

A patient presents with swelling (edema) in their ankle after an injury. Which property of areolar connective tissue best explains this phenomenon?

Accepted Answer

Its loose arrangement of fibers allows fluid to soak up when inflamed.

Question 3

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

Accepted Answer

A fluid or gel-like unstructured material that fills the space between cells

Question 4

A tendon is primarily composed of which type of connective tissue, and what property does this tissue provide?

Accepted Answer

Dense regular connective tissue; provides great resistance to pulling forces in one direction

Question 5

Which of the following cell types is responsible for producing the fibers and ground substance in connective tissue proper?

Accepted Answer

Fibroblasts

Question 6

A biopsy of a lymph node reveals a network of fibers supporting free blood cells. Which type of connective tissue is most likely present?

Accepted Answer

Reticular connective tissue

Question 7

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

Accepted Answer

It is avascular, so nutrients and repair cells cannot easily reach damaged areas.

Question 8

Which connective tissue fiber type is most responsible for providing high tensile strength to tissues such as tendons and ligaments?

Accepted Answer

Collagen fibers

Question 9

A patient with a genetic defect in the synthesis of elastic fibers would most likely have problems in which of the following structures?

Accepted Answer

Artery walls, leading to reduced ability to stretch and recoil

Question 10

Which of the following equations best represents the relationship between the density of fibers ($D$), the number of fibers ($N$), and the volume of the tissue ($V$) in connective tissue, assuming uniform distribution?

Accepted Answer

$D = \frac{N}{V}$

Question 11

Which of the following is a key difference between dense regular and dense irregular connective tissue?

Accepted Answer

Dense regular tissue has parallel collagen fibers for resistance to pull in one direction, while dense irregular tissue has thick, irregularly arranged fibers for resistance to tension from many directions.

Question 12

Which of the following best describes the role of blood as a connective tissue?

Accepted Answer

It transports nutrients, gases, and wastes throughout the body.

Question 13

A patient is found to have a deficiency in macrophages within their connective tissue. Which function would be most directly impaired?

Accepted Answer

Phagocytosis of pathogens and dead cells

Question 14

Which of the following statements about adipose tissue is TRUE?

Accepted Answer

Brown fat is specialized for rapid heat production.

Question 15

Which of the following best explains why bone is considered a connective tissue?

Accepted Answer

It contains a mineralized extracellular matrix produced by osteoblasts.

Question 16

A researcher is studying the rate of diffusion of nutrients through cartilage. Which property of cartilage is most relevant to this process?

Accepted Answer

Cartilage is avascular, so nutrients must diffuse slowly through the matrix.

Question 17

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

Accepted Answer

They form delicate networks that support free blood cells in lymphoid organs.

Question 18

Which of the following is a characteristic that distinguishes connective tissue from other primary tissue types?

Accepted Answer

It has a large amount of extracellular matrix relative to cells.

Question 19

A patient with a genetic disorder affecting collagen synthesis would most likely experience which of the following symptoms?

Accepted Answer

Weakness in tendons and ligaments due to reduced tensile strength

Question 20

Which of the following best explains why dense regular connective tissue is found in tendons and ligaments, but not in the dermis of the skin?

Accepted Answer

Tendons and ligaments require resistance to tension in one direction, while the dermis needs resistance to tension from multiple directions.
