Question 2

Which of the following is an example of a syndesmosis?

Accepted Answer

The distal connection between the tibia and fibula.

Question 3

What is the primary function of synovial fluid in a synovial joint?

Accepted Answer

To nourish articular cartilage and remove metabolic waste.

Question 4

Which type of joint is classified as amphiarthrotic and is made up of fibrocartilage between bones?

Accepted Answer

Symphysis

Question 5

A patient presents with pain, swelling, and warmth in the shoulder after repetitive overhead movements. Which condition is most likely?

Accepted Answer

Question 8

During vigorous exercise, what happens to synovial fluid and articular cartilage?

Question 9

Which of the following best describes the difference between origin and insertion of a muscle?

Accepted Answer

Origin is the attachment to the immovable bone; insertion is the attachment to the movable bone.
