Example Question #21 : Identifying Types Of Joints
The joints of the knuckles are examples of __________ joints.
saddle
gliding
condylar
hinge
ball-and-socket
condylar
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 __________.
articulation of the first rib to the sternum, which is a synchondrosis
articulation of the seventh rib to the sternum, which is a synostosis
articulation of the seventh rib to the sternum, which is a synchondrosis
articulation of the first rib to the sternum, which is a syndesmosis
articulation of the first rib to the sternum, which is a synchondrosis
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 __________.
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 hinge joint, and the intercarpal joints are gliding joints
the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints
the radiocarpal joint is a condylar joint, and the intercarpal joints are gliding joints
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.
