Identify the type of joint shown in the picture.

Question

Match List I with List II:

List I		List II
A	EFibrous joints	I	Adjacent vertebrae, limited movement
B	Cartilaginous joints	II	Humerus and Pectoral girdle, rotational movement
C	Hinge joints	III	Skull, don’t allow any movement
D	Ball and socket joints	IV	Knee, help in locomotion

Choose the correct answer from the options given below:

Answer 1

Clinical pearl first: ribs articulate with the vertebral column at two synovial joints, the costovertebral joint (head of rib) and the costotransverse joint (tubercle of rib with the transverse process). The image shows the rib tubercle meeting the transverse process, so this is a costotransverse synovial joint.

Use elimination to confirm. A syndesmosis is fibrous (think tibiofibular). A synarthrosis is fixed and immovable. A symphysis is cartilaginous (think pubic symphysis or intervertebral disc). All rib-to-vertebra and rib-to-sternum articulations of the plane variety, including interchondral, sternocostal, costovertebral and costotransverse, belong to the synovial group. Therefore the answer is synovial joint.
