Accepted Answer

Collateral ligaments, cruciate ligaments, and cartilage (menisci)

Question 4

Which type of synovial joint allows movement in multiple axes, such as the shoulder joint?

Accepted Answer

Ball-and-socket joint

Question 5

Which of the following movements describes decreasing the angle between two bones, such as bending the elbow?

Accepted Answer

Flexion

Question 6

A patient is diagnosed with Lyme disease after a tick bite. Which of the following is a consequence of untreated Lyme disease affecting joints?

Accepted Answer

Chronic inflammation leading to arthritis

Question 7

Which of the following is a major factor that stabilizes synovial joints?

Accepted Answer

The shape of the articular surfaces

Question 8

Which equation best represents the regeneration of ATP via creatine phosphate during muscle contraction?

Accepted Answer

Question 9

Which of the following best describes the sliding filament model of muscle contraction?

Accepted Answer

Actin filaments slide past myosin filaments, shortening the sarcomere.

Question 10

Which of the following is a characteristic unique to cardiac muscle tissue compared to skeletal and smooth muscle?

Accepted Answer

Intercalated discs and involuntary control

Question 11

During muscle contraction, which structure stores and releases calcium ions?

Accepted Answer

Sarcoplasmic reticulum

Question 12

Which of the following is the correct sequence of events at the neuromuscular junction leading to muscle fiber stimulation?

Accepted Answer

Action potential arrives, acetylcholine released, acetylcholine binds receptors, muscle fiber depolarizes

Question 13

Which prefix is commonly used in muscle terminology to indicate a relationship to muscle?

Accepted Answer

Myo-

Question 14

Which of the following is a homeostatic imbalance at the neuromuscular junction characterized by muscle weakness due to loss of acetylcholine receptors?

Accepted Answer

Myasthenia gravis

Question 15

Which of the following is a function of bursae in synovial joints?

Accepted Answer

To reduce friction between moving structures

Question 16

Which type of arthritis is characterized by autoimmune destruction of joint tissues?

Accepted Answer

Rheumatoid arthritis

Which connective tissue sheath surrounds an individual muscle fiber?

Accepted Answer

Endomysium

Question 18

A patient receives Botox injections to treat muscle spasms. Which of the following best explains the effect of Botox at the neuromuscular junction?

Accepted Answer
