The internal layer is the synovial membrane (loose connective tissue proper) which covers all internal joint surfaces that are not hyaline cartilage. Synovial joints are reinforced by a number of ligaments. Ligaments are bands of dense regular connective tissue proper that connect bones to other bones.
The cell membrane of a muscle cell is called the sarcolemma, and this membrane, like that of neurons, maintains a membrane potential. So, impulses travel along muscle cell membranes just as they do along nerve cell membranes. However, the 'function' of impulses in muscle cells is to bring about contraction. To understand how a muscle contracts, you need to know a bit about the structure of muscle cells. Skeletal muscle is the muscle attached to the skeleton.
