The impulse travels over the sarcolemma in all directions, Each muscle fiber is directly surrounded by connective tissue called the Repeated acute episodes of bursitis can result in a chronic condition. Bursae contain a lubricating fluid that serves to reduce friction between structures. True or False: The structural classification of joints is based on the composition of the binding material and the presence or absence of a joint cavity.

Muscles obtain their energy through anaerobic respiration of glucose; this is beneficial because anaerobic repsiration can generate energy quickly Finally, an articular disc can serve to smooth the movements between the articulating bones, as seen at the temporomandibular joint. The joint responds by increasing production of the lubricating synovial fluid, but this can lead to swelling of the joint cavity, causing pain and joint stiffness as the articular capsule is stretched. Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane.

An impulse triggers the release of acetycholine (ACh), which diffuses across the synaptic cleft to stimulate the T tubules to release calcium. The hip joint and the glenohumeral (shoulder) joint are the only ball-and-socket joints of the body. Osteoarthritis (OA) of the spine involves the facet joints (located in the posterior aspect of the vertebral column) and are the only true synovial joints between adjacent spinal levels.
