Synovial membranes are connective tissue membranes that line the cavities of the freely movable joints such as the shoulder, elbow, and knee.
Membrane
A membrane is a selective barrier; it lets some items pass but prevents others from doing so. These entities could be ions, molecules, or other tiny particles. Biological and manufactured membranes are the two broad categories into which membranes can be placed. Cell membranes, which are the exterior coverings of cells or organelles that permit the passage of specific components, nuclear membranes, which enclose the cell nucleus, and tissue membranes like mucosae and serosae are all examples of biological membranes. Humans create synthetic membranes for use in laboratories and industries (such as chemical plants).

Answer;
The nervous system is composed of two basic cell types, namely, the Neurons and the neuroglial cells.
Explanation;
The nervous tissue is the main component of the nervous system which includes the brain, spinal cords and the nerves. It is a specialized tissue found in the central nervous system (brain and the spinal cord) and the peripheral nervous system (nerves). It consist of the neurons and the supporting cells called neuroglia.
The neurons are responsible for conducting and generating nerve impulses.
Neuroglial or glia cells are involved in many specialized functions apart from supporting of the neurons. There are six in number; four in the CNS and two in the PNS.
