Muscles provide stability to joints, and there is a direct correlation between muscle strength and joint stability, particularly with synovial joints. Each specific joint has a unique vascular supply and innervation scheme patterns do exist. The bones either develop directly through intramembranous ossification or indirectly through endochondral ossification. Joints, comprising bones and connective tissue, are embryologically derived from mesenchyme. The two classification schemes can be correlated: synarthroses are fibrous, amphiarthroses are cartilaginous, and diarthroses are synovial. Histological classification is based on the dominant type of connective tissue, and functional classification is based on the amount of movement permitted. Histologically the three joints in the body are fibrous, cartilaginous, and synovial. Functionally the three types of joints are synarthrosis (immovable), amphiarthrosis (slightly moveable), and diarthrosis (freely moveable). Joints can be classified either histologically or functionally. ![]() A joint is a point where two bones make contact.
