Synovial membrane is primarily composed of which type of tissue?

1. Muscle Tissue

2. Connective Tissue

3. Epithelial Tissue

4. Nervous Tissue

The correct answer is: Connective Tissue

The synovial membrane is primarily composed of connective tissue, which plays a crucial role in its structure and function. This type of tissue provides the necessary support, elasticity, and strength to the membrane. Connective tissue consists of various cell types and extracellular matrix components, which help in creating a flexible and durable layer that lines the cavities of synovial joints. The connective tissue of the synovial membrane also contains specialized cells, such as synoviocytes, that are responsible for the secretion of synovial fluid, which lubricates the joints and reduces friction during movement. Additionally, while epithelial tissue does play a role in the function of the synovial membrane—specifically through its presence in the synovial lining—the predominant type of tissue that constitutes the membrane itself and defines its characteristics is connective tissue. Other tissue types, such as muscle and nervous tissue, do not have a direct association with the structure or primary function of the synovial membrane, hence they are not considered the main components of this specific tissue type.
