Question

multiple choice question

how do fibrous or cartilaginous joints become bony joints?

they lose their ligaments.
they ossify.
they are pulled apart.

Explanation:

Define bony joints and synostosis

Using the Bony Joints and Synostosis knowledge points, we identify that a bony joint, or synostosis, is an immobile joint formed when the gap between two bones ossifies and they become, in effect, a single bone.

Analyze the mechanism of transformation

Fibrous or cartilaginous joints can undergo mineralization and bone deposition. This process of bone formation is called ossification, which replaces the intervening connective tissue with bone tissue.

Evaluate the given options

• "They lose their ligaments": Losing ligaments does not turn a joint into bone.
• "They ossify": This is the correct biological process where tissue converts into bone.
• "They are pulled apart": Separation does not lead to fusion or bone formation.

Answer:

• They lose their ligaments.
• They ossify. (Correct answer)
• They are pulled apart.
