Multiple Choice

Which of the following best distinguishes synovial joints from nonsynovial joints?

Nonsynovial joints are always immovable, while synovial joints are always immobile.

Synovial joints have a fluid-filled cavity, while nonsynovial joints do not.

Synovial joints are only found in the axial skeleton, while nonsynovial joints are only in the appendicular skeleton.

Nonsynovial joints allow for a greater range of motion than synovial joints.

Verified step by step guidance

Step 1: Begin by understanding the key characteristics of synovial joints. Synovial joints are a type of joint in the human body that are characterized by the presence of a fluid-filled cavity called the synovial cavity. This cavity is filled with synovial fluid, which reduces friction and allows for smooth movement between the articulating bones.

Step 2: Contrast synovial joints with nonsynovial joints. Nonsynovial joints, also known as solid joints, lack a synovial cavity and are typically connected by fibrous tissue or cartilage. These joints generally allow for limited or no movement, depending on their structure.

Step 3: Evaluate the options provided in the problem. The first option incorrectly states that nonsynovial joints are always immovable and synovial joints are always immobile, which is not true. Synovial joints are highly mobile, while nonsynovial joints can range from immovable to slightly movable.

Step 4: Analyze the second option, which states that synovial joints have a fluid-filled cavity while nonsynovial joints do not. This is accurate and aligns with the anatomical distinction between these two types of joints.

Step 5: Review the remaining options. The third option incorrectly associates synovial joints with the axial skeleton and nonsynovial joints with the appendicular skeleton, which is anatomically incorrect. The fourth option incorrectly claims that nonsynovial joints allow for a greater range of motion than synovial joints, which contradicts the functional characteristics of these joints.
