Question 1

Which of the following best describes the primary function of areolar connective tissue?

Accepted Answer

Cushions organs, provides support but permits independent movement, and acts as a reservoir for water and salts

Question 2

A patient with a genetic defect in collagen synthesis would most likely have problems with which type of connective tissue?

Accepted Answer

Dense regular connective tissue

Question 3

Which cell type is most abundant in areolar connective tissue and is responsible for producing fibers and ground substance?

Accepted Answer

Fibroblast

Question 4

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

Accepted Answer

It is avascular and lacks nerves, relying on diffusion from the perichondrium for nutrients

Question 5

A newborn is found to have difficulty maintaining body temperature. Which connective tissue is most likely underdeveloped?

Accepted Answer

Brown adipose tissue

Question 6

Which of the following is a characteristic of dense regular connective tissue?

Accepted Answer

Fibers (mainly collagen) run in the same direction, providing tensile strength

Question 7

Which connective tissue type forms the stroma or framework of lymph nodes, spleen, and bone marrow?

Accepted Answer

Reticular connective tissue

Question 8

A ligament is torn in an athlete. Which type of connective tissue is primarily involved, and what is a key property of this tissue?

Accepted Answer

Dense regular connective tissue; fibers run parallel for high tensile strength

Question 9

Which of the following best describes the main function of fibrocartilage?

Accepted Answer

Withstands pressure and provides support, as in intervertebral discs and knee cartilage

Question 10

Which connective tissue type is found in the dermis of the skin and provides resistance to tension from multiple directions?

Accepted Answer

Dense irregular connective tissue

Question 11

A histological slide shows chondrocytes in lacunae surrounded by a matrix with many elastic fibers. Where is this tissue most likely found?

Accepted Answer

Epiglottis and external ear

Question 12

Which of the following statements about adipose tissue is correct?

Accepted Answer

It is well vascularized, with adipocytes as the main cell type, and stores energy

Question 13

Which type of cartilage is found at the ends of long bones, in the nose, and in the trachea?

Accepted Answer

Hyaline cartilage

Question 14

Which of the following best explains why dense regular connective tissue heals slowly after injury?

Accepted Answer

It is poorly vascularized, limiting nutrient and oxygen delivery

Question 15

Which connective tissue type is most likely to be found forming the capsules of organs such as the kidneys and sheaths around nerves and muscles?

Accepted Answer

Dense irregular connective tissue

Question 16

A tissue sample is composed of mostly parallel collagen fibers with few cells. Which of the following equations best represents the tensile strength ($$T) of $$this tissue, given that tensile strength is proportional to the number of collagen fibers ($$n) $$and the cross-sectional area ($$A$$)?

Accepted Answer

$$T = n 	imes A$$

Question 17

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

Accepted Answer

Forming the stroma of lymph nodes

Question 18

Which connective tissue type is most likely to be found in the walls of large arteries, allowing them to stretch and recoil?

Accepted Answer

Elastic connective tissue

Question 19

Which of the following best describes the ground substance in cartilage?

Accepted Answer

Rich in chondroitin sulfate and hyaluronic acid

Question 20

A child with a genetic disorder affecting chondrocyte function is most likely to have problems with which of the following?

Accepted Answer

Formation of articular cartilage at the ends of long bones
