$$\text{Viscosity} \propto \text{Water Amount}$$

Question 1

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

Accepted Answer

Transmitting electrical impulses

Question 2

All connective tissues share a common embryonic origin. From which tissue do they arise?

Accepted Answer

Mesenchyme

Question 3

Which connective tissue class is highly vascularized and functions in support and protection?

Accepted Answer

Bone

Question 4

A patient suffers a ligament injury. Which type of connective tissue is most likely affected?

Accepted Answer

Dense regular connective tissue

Question 5

Which of the following best describes the extracellular matrix (ECM) of connective tissue?

Accepted Answer

It is composed of ground substance and fibers, providing support and allowing tissues to bear weight.

Question 6

Which type of connective tissue fiber is most abundant and provides high tensile strength?

Accepted Answer

Collagen fibers

Question 7

A tissue sample reveals networks of long, thin fibers that allow for stretch and recoil. Which fiber type is present?

Accepted Answer

Elastic fibers

Question 8

Which cell type in connective tissue is responsible for secreting ground substance and ECM fibers?

Accepted Answer

Fibroblasts

Question 9

Which connective tissue subtype acts as a universal packing material and reservoir for water and salts?

Accepted Answer

Areolar connective tissue

Question 10

A patient with a deficiency in chondroitin sulfate and hyaluronic acid would most likely have issues with which connective tissue component?

Accepted Answer

Ground substance

Question 11

Which connective tissue cell type is primarily involved in the local inflammatory response by releasing heparin and histamine?

Accepted Answer

Mast cells

Question 12

Which connective tissue subtype is found in lymph nodes, spleen, and bone marrow, providing a mesh-like stroma for blood cells?

Accepted Answer

Reticular connective tissue

Question 13

Which of the following equations best represents the relationship between the viscosity of ground substance and the amount of water trapped?

Accepted Answer

$$	ext{Viscosity} \propto 	ext{Water Amount}$$

Question 14

Which connective tissue subtype is poorly vascularized and consists mostly of parallel collagen fibers, making it resistant to pulling forces?

Accepted Answer

Dense regular connective tissue

Question 15

Which connective tissue subtype is found in the walls of large arteries and allows for stretch and recoil?

Accepted Answer

Elastic connective tissue

Question 16

A patient with a genetic defect in fibroblast function would most likely have problems with which of the following?

Accepted Answer

Production of collagen and ground substance in connective tissue proper

Question 17

Which connective tissue cell type is responsible for storing nutrients and is found in subcutaneous tissue?

Accepted Answer

Adipocytes

Question 18

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

Accepted Answer

Cartilage is avascular, so nutrients and repair cells reach it slowly.

Question 19

Which connective tissue subtype is most likely to be found in fibrous joint capsules and the dermis, resisting tension from many directions?

Accepted Answer

Dense irregular connective tissue

Question 20

A patient with a compromised immune system is found to have a deficiency in phagocytic cells that 'eat' dead cells and microorganisms. Which cell type is most likely deficient?

Accepted Answer

Macrophages
