Question 6

A biopsy reveals a tissue with cells embedded in a rigid matrix containing collagen fibers and chondrocytes in lacunae. Which tissue is most likely being observed?

Accepted Answer

Cartilage

Question 7

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

Question 9

A patient has a bone fracture that is healing. Which bone cell type is primarily responsible for building new bone matrix during this process?

Accepted Answer

Osteoblasts

Question 10

Which of the following is a function of the axial skeleton?

Accepted Answer

Protecting the brain and spinal cord

Question 11

A long bone is composed of both compact and spongy bone. Which of the following best describes the location and function of spongy bone?

Accepted Answer

Located in the epiphyses, it reduces bone weight and contains red marrow for hematopoiesis.

Question 12

Which of the following best explains why bone remodeling is important throughout life?

Accepted Answer

It allows bones to adapt to stress, repair micro-damage, and regulate calcium levels.

Question 13

A patient is diagnosed with osteoporosis, a condition characterized by decreased bone mass. Which of the following best explains the underlying cause?

Accepted Answer

Osteoclast activity exceeds osteoblast activity, leading to bone resorption.

Question 17

Which of the following equations correctly represents the relationship between bone mass, bone formation, and bone resorption?

Accepted Answer

$$\Delta M = F - R$$

Question 18

A child is diagnosed with rickets, a disease caused by vitamin D deficiency. Which process is most directly impaired?

Accepted Answer
