Example Question #21 : Identifying Types Of Joints

The joints of the knuckles are examples of __________ joints.

Possible Answers:

ball-and-socket

condylar

saddle

gliding

hinge

Correct answer:

condylar

Explanation:

Condylar or ellipsoid joints involve one bone that is concave and one bone that is convex. The metacarpophalangeal joints of the knuckles, as well as the wrist joint, are both condylar. As for the other bones of the hand, the intercarpal joints are gliding and the interphalangeal joints are hinge.

Example Question #22 : Identifying Types Of Joints

Sternocostal joints are all gliding joints, except the __________.

Possible Answers:

articulation of the seventh rib to the sternum, which is a synostosis

articulation of the first rib to the sternum, which is a syndesmosis

articulation of the seventh rib to the sternum, which is a synchondrosis

articulation of the first rib to the sternum, which is a synchondrosis

Correct answer:

articulation of the first rib to the sternum, which is a synchondrosis

Explanation:

Where the first rib meets the manubrium (top of sternum), the joint is cartilaginous and called a synchondrosis. Syndesmoses are fibrous joints of connective tissue, and syostoses are areas of bone fusion.

Example Question #23 : Identifying Types Of Joints

The radiocarpal joint differs from the intercarpal joints in that __________.

Possible Answers:

the radiocarpal joint is a condylar joint, and the intercarpal joints are hinge joints

the radiocarpal joint is a gliding joint, and the intercarpal joints are condylar joints

the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints

the radiocarpal joint is a hinge joint, and the intercarpal joints are gliding joints

Correct answer:

the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints

Explanation:

The radiocarpal or wrist joint is a condylar synovial joint because the radius has a concave surface, and the carpals have a convex surface. The joint connects the radius with the scaphoid, lunate, and triquetrum.
