Multiple Choice

How do synovial joints form during human development?

By the direct ossification of mesenchymal tissue without any intermediate cartilage

By the fusion of two separate bones after birth

By the accumulation of adipose tissue between developing bones

By the differentiation of mesenchymal tissue into cartilage, followed by cavitation to create a joint space

Verified step by step guidance

Understand that synovial joints are specialized structures that allow free movement between bones, and their formation is a complex developmental process.

Recognize that mesenchymal tissue is the embryonic connective tissue that gives rise to various structures, including cartilage and bone.

Learn that during synovial joint development, mesenchymal tissue first differentiates into cartilage, forming a temporary cartilaginous model of the joint.

Explore the process of cavitation, where programmed cell death (apoptosis) occurs within the cartilaginous model to create a joint cavity or space.

Note that the surrounding mesenchymal tissue differentiates into structures like the synovial membrane, ligaments, and joint capsule, completing the formation of the synovial joint.
