Question 1

Which of the following best describes the main function of areolar connective tissue in the human body?

Accepted Answer

It acts as a universal packing material, supporting and binding other tissues.

Question 2

A patient suffers a tendon injury. Which connective tissue type is most likely affected, and what is its primary structural feature?

Accepted Answer

Dense regular connective tissue; parallel bundles of collagen fibers

Question 3

Which cell type is responsible for producing the extracellular matrix in cartilage during growth?

Accepted Answer

Chondroblasts

Question 4

A biopsy reveals tissue with closely packed adipocytes and a sparse matrix. Which tissue is this, and what is its main function?

Accepted Answer

Adipose tissue; stores energy and insulates against heat loss

Question 5

Which connective tissue type is avascular and receives nutrients by diffusion from the perichondrium?

Accepted Answer

Cartilage

Question 6

Which of the following best explains why cartilage injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and chondrocytes lose their ability to divide with age.

Question 7

Which connective tissue is most specialized for transport of gases, nutrients, and wastes?

Accepted Answer

Blood

Question 8

A patient with a heart attack develops scar tissue in the myocardium. Which process is primarily responsible for this, and what is a likely consequence?

Accepted Answer

Fibrosis; impaired muscle contraction and possible heart failure

Question 9

Which of the following tissues has the highest regenerative capacity?

Accepted Answer

Epithelial tissue

Question 10

Which of the following is a correct pairing of connective tissue fiber type and its function?

Accepted Answer

Reticular fibers – form supportive networks in soft tissues

Question 11

Which membrane lines body cavities that are open to the exterior and is composed of an epithelial layer overlying loose connective tissue?

Accepted Answer

Mucous membrane

Question 12

Which muscle tissue type is involuntary, striated, and contains intercalated discs?

Accepted Answer

Cardiac muscle

Question 13

Which of the following best describes the function of nervous tissue?

Accepted Answer

Transmits electrical signals for communication and control

Question 14

A tissue sample shows spindle-shaped cells with a single central nucleus and no visible striations. Where is this tissue most likely found?

Accepted Answer

Walls of hollow organs such as the intestines

Question 15

Which of the following is true regarding the embryonic origin of tissues?

Accepted Answer

Muscle and connective tissues arise mostly from mesoderm.

Question 16

Which of the following best explains why arteries contain a high proportion of elastic fibers in their walls?

Accepted Answer

To allow for stretch and recoil as blood pulses through

Question 17

A patient with a spleen injury is found to have damage to the tissue that forms a soft internal skeleton supporting blood cells. Which tissue is affected?

Accepted Answer

Reticular connective tissue

Question 18

Which of the following is a function of bone (osseous) tissue?

Accepted Answer

Support and protection of body structures

Question 19

Which step in tissue repair involves the formation of granulation tissue and the restoration of blood supply?

Accepted Answer

Organization

Question 20

Which of the following best describes the difference between 'blast' and 'cyte' cells in connective tissue?

Accepted Answer

'Blast' cells are immature and actively secrete matrix; 'cyte' cells are mature and maintain the matrix.
