BIOD 331 MODULE 10 EXAM VERSION 1
1. Each of the following are true of gout except:
A. Uric acid dissolves readily in synovial fluid
B. Hyperuricemia can lead to crystal deposition in joints
C. Gout commonly affects the first metatarsophalangeal joint
D. Acute attacks are characterized by inflammation and pain
Correct Answer: A. Uric acid dissolves readily in synovial fluid
Verified Explanation:
,Uric acid is only sparingly soluble in synovial fluid, especially at lower
temperatures, facilitating the precipitation of monosodium urate crystals in
peripheral joints such as the first metatarsophalangeal joint. Hyperuricemia
predisposes individuals to gout because exceeding uric acid solubility results
in crystal formation and subsequent inflammatory response. Thus, option A is
incorrect and does not accurately describe gout's pathophysiology.

2. Which of the following would a patient likely exhibit on an initial
physical exam if you suspect they have OA? (mark all that apply):
A. Capsular pattern
B. Crepitus with movement
C. Erythema
D. Systemic symptoms
Correct Answers: A. Capsular pattern, B. Crepitus with movement
Verified Explanation:
Osteoarthritis typically presents with a capsular pattern (joint stiffness,
especially after inactivity) and crepitus (grating sensation) with movement
due to articular cartilage degeneration. Systemic symptoms and pronounced
erythema are more characteristic of inflammatory arthritides, such as
rheumatoid arthritis, rather than OA.

3. Which of the following are true regarding synostoses? (mark all
that apply):
A. They allow no movement between them
B. They are joined by dense connective tissue
, C. They are temporary structures
D. They involve bony fusion
Correct Answers: A. They allow no movement between them; B.
They are joined by dense connective tissue (Note: Option D could also
be correct if provided)
Verified Explanation:
Synostoses are joints where the bones have fused together, resulting in an
immobile joint. They are characterized by the presence of dense connective
tissue that ossifies over time. This structural arrangement is designed to
eliminate movement, as seen in the epiphyseal plates of long bones after
growth ceases.

4. Blood circulates through bone by what means? (mark all that
apply):
A. Via central Haversian and Volkmann canals
B. An anastomosis between perforating and nutrient arteries
C. Diffusion through endosteal surface of the bone and the canaliculi
D. Only via periosteal arteries
Correct Answers: A. Via central Haversian and Volkmann canals; B. An
anastomosis between perforating and nutrient arteries; C. Diffusion through
endosteal surface of the bone and the canaliculi
Verified Explanation:
Cortical bone is vascularized by a network of central (Haversian) canals and
transverse (Volkmann) canals interconnected by anastomosing arteries.
Blood and nutrients are also provided by diffusion through the endosteal
