Question

multiple choice question

which joint classifications are used to describe how the bone ends of a joint are held together?

monaxial, biaxial, or multiaxial
synarthrodial, diarthrodial, or amphiarthrodial
bony, fibrous, cartilaginous, or synovial

Explanation:

Analyze structural classification criteria

Using the Joint Classification knowledge point

Joints are classified structurally based on the material binding the bones together and whether a joint cavity is present. These structural categories describe exactly how the bone ends are held together:

• Bony joints (synostoses) are fused bones.
• Fibrous joints are held together by collagen fibers.
• Cartilaginous joints are held together by cartilage.
• Synovial joints are enclosed by a joint capsule containing synovial fluid.

Compare with functional classifications

Functional classification is based on the degree of movement permitted at the joint:

• Synarthrosis (immovable), amphiarthrosis (slightly movable), and diarthrosis (freely movable).
• Monaxial, biaxial, and multiaxial describe the axes of motion, which is also a functional/mechanical description rather than physical binding.

Select the correct option

The structural categories (bony, fibrous, cartilaginous, or synovial) directly describe the physical medium holding the bone ends together.

Answer:

• Monaxial, biaxial, or multiaxial
• Synarthrodial, diarthrodial, or amphiarthrodial
• Bony, fibrous, cartilaginous, or synovial (Correct answer)
