Question 1

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

Accepted Answer

It determines the specialized function of the tissue by providing the majority of tissue volume and consisting of fibers and ground substance.

Question 2

A patient suffers a ligament injury. Which type of connective tissue is primarily involved, and what is its main structural characteristic?

Accepted Answer

Dense regular connective tissue; it contains tightly packed, parallel collagen fibers.

Question 3

Which cell type in connective tissue is responsible for producing ground substance and protein fibers, and is the most abundant in connective tissue proper?

Accepted Answer

Fibroblasts

Question 4

A newborn is found to have a high amount of brown fat. What is the physiological significance of this tissue?

Accepted Answer

It provides insulation and releases energy to warm the body due to its high mitochondrial content.

Question 5

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

Accepted Answer

Chondrocytes produce antiangiogenesis factor, which discourages the formation of blood vessels in cartilage.

Question 6

Which connective tissue fiber type is most responsible for providing strength and flexibility, and is the most common in connective tissue proper?

Accepted Answer

Collagen fibers

Question 7

A patient presents with swelling and redness after an injury. Which connective tissue cell is most likely responsible for this inflammatory response, and what substances does it release?

Accepted Answer

Mast cells; they release histamine and heparin.

Question 8

Which of the following best describes the difference between dense regular and dense irregular connective tissue?

Accepted Answer

Dense regular connective tissue has parallel collagen fibers, while dense irregular connective tissue has interwoven collagen fibers that resist forces from multiple directions.

Question 9

Which type of connective tissue forms the stroma (supportive framework) of organs such as the spleen and lymph nodes?

Accepted Answer

Reticular tissue

Question 10

A patient with a spinal cord injury is found to have damage to the elastic ligaments of the spinal column. Which type of connective tissue is primarily affected?

Accepted Answer

Elastic tissue

Question 11

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

Accepted Answer

It fills the space between cells, surrounds fibers, and slows pathogen movement.

Question 12

Which of the following is a correct pairing of a tissue membrane and its function?

Accepted Answer

Cutaneous membrane: forms the thick, relatively waterproof skin covering the body

Question 13

Which of the following statements about bone (osseous tissue) is correct?

Accepted Answer

Osteocytes are found in lacunae and are arranged around central canals within the matrix.

Question 14

A patient is diagnosed with a deficiency in the production of antibodies. Which connective tissue cell type is most likely affected?

Accepted Answer

Lymphocytes

Question 15

Which of the following best explains why areolar tissue is considered the 'packing material' of the body?

Accepted Answer

It is loosely organized with a viscous ground substance, collagen, and elastic fibers, filling spaces and providing cushioning.

Question 16

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

Accepted Answer

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

Question 17

Which of the following best describes the difference between white fat and brown fat?

Accepted Answer

Brown fat is found in babies and young children, is more vascularized, and its breakdown releases energy to warm the body.

Question 18

A patient with a ruptured intervertebral disc is experiencing pain due to bone-to-bone contact. Which type of cartilage is most likely damaged?

Accepted Answer

Fibrocartilage

Question 19

Which of the following best describes the role of the perichondrium in cartilage?

Accepted Answer

It provides support and protection (outer fibrous layer) and is involved in growth and repair (inner cellular layer).

Question 20

Which of the following best explains why synovial membranes are unique among tissue membranes?

Accepted Answer

They lack a true epithelium and produce synovial fluid for joint lubrication.
