Question

Which of the following bones articulate at a synovial joint?

a. skull bones
b. radius and ulna
c. bones of the pubis
d. humerus and scapula

Answer 1

The radius and ulna, along with the humerus and scapula, are the bones that articulate at synovial joints, allowing for a range of movements. The correct options are B, and D.

Step-by-step explanation:

The bones that articulate at a synovial joint are the radius and ulna, along with the humerus and scapula. The radius and ulna articulate with each other as well as with the carpal bones, allowing for rotation of the forearm.

The humerus also articulates with the scapula at the shoulder, which is another example of a synovial joint. In contrast, the skull bones are connected by sutures, which are immovable joints, and the bones of the pubis are joined by a symphysis, which is an amphiarthrosis joint.
