Final answer:
Ankylosis is the condition of stiffening and immobility of a joint, typically associated with Synarthrosis, a type of immobile joint. It is different from Hemarthrosis, Fibrositis, Bursitis, and Kyphosis, and can result from severe arthritis or joint damage.
Step-by-step explanation:
The condition of stiffening and immobility of a joint is known as Ankylosis. This term refers to a severe loss of mobility in a joint, which may be due to abnormal adhesion and rigidity of the bones of the joint. Ankylosis is different from other joint conditions such as Hemarthrosis (bleeding into a joint space), Fibrositis (inflammation of the fibrous tissue), Bursitis (inflammation of a bursa), and Kyphosis (a curving of the spine that causes a bowing or rounding of the back).
Types of joints by functional classification include Synarthrosis (an immobile joint), Amphiarthrosis (a slightly movable joint), and Diarthrosis (a freely movable joint). Ankylosis is typically associated with Synarthrosis, where there is a strong union between the bones that provide protection and support to internal organs, as seen in the sutures of the skull and the manubriosternal joint.
Arthritis is one common cause of joint stiffness and th ending up with Ankylosis. In severe cases of arthritis or joint damage, joint replacement surgery may be necessary to restore mobility.
