SYNOVIAL MEMBRANES Meaning and
Definition
-
Synovial membranes are specialized connective tissue membranes that line the joint cavities of synovial joints. These membranes play a crucial role in the lubrication and movement of the joints.
The synovial membrane consists of two main layers - an outer fibrous layer and an inner synovial layer. The outer fibrous layer, also known as the intima, is composed of dense irregular connective tissue. It provides structural support and helps to contain the synovial fluid within the joint cavity. The inner synovial layer, or synovium, is a thin and delicate layer consisting of synoviocytes and loose connective tissue.
The synovial membrane is responsible for producing synovial fluid, a clear and viscous fluid that lubricates the joint surfaces. Synovial fluid facilitates smooth movement by reducing friction between the articular cartilage surfaces of the bones. It also provides nutrients to the joint cartilage, helping to maintain its health and function.
In addition to lubrication, synovial membranes serve a protective function by producing antibodies and phagocytic cells that help defend the joint against infection and inflammation. They also play a role in joint stability, as the synovial membrane helps to form the joint capsule and provides support to the surrounding ligaments and tendons.
Overall, synovial membranes are a vital component of synovial joints, contributing to joint lubrication, nutrient supply, protection against infection, and joint stability.

Etymology of SYNOVIAL MEMBRANES
The word "synovial" is derived from the Latin word "synovia", which referred to the lubricating fluid found in joints. The term "synovia" originated from the Greek word "synoviā", combining "syn" meaning "together" and "oviā" meaning "egg" or "egg white". This descriptive term was likely chosen because synovial fluid has a somewhat viscous and egg-like consistency. The word "membranes" derives from the Latin word "membrāna", meaning "thin skin" or "layer", which refers to the thin, inner layer of tissue that lines the joint cavities. Therefore, when combined, "synovial membranes" refers to the thin, lubricating tissue layers found in the joints.
