In two different planes

In only one plane

No movement at all

Previous problemNext problem

Verified step by step guidance

Step 1: Begin by understanding the term 'biaxial joint.' A biaxial joint is a type of synovial joint that allows movement in two planes or axes. Examples include the wrist joint (radiocarpal joint) and the metacarpophalangeal joints of the fingers.

Step 2: Review the types of movement possible in synovial joints. Synovial joints are classified based on the number of axes or planes in which they allow movement: uniaxial (one plane), biaxial (two planes), and multiaxial (three or more planes).

Step 3: Compare the options provided in the question. The correct answer should align with the definition of a biaxial joint, which allows movement in two different planes.

Step 4: Eliminate incorrect options. For example, 'In three or more planes' describes a multiaxial joint, and 'In only one plane' describes a uniaxial joint. 'No movement at all' refers to immovable joints like sutures in the skull.

Step 5: Conclude that the correct answer is 'In two different planes,' as this matches the definition and characteristics of a biaxial joint.
