WebEach skeletal muscle fiber is controlled by a neuron at a single __________. neuromuscular junction. Match the following description of the homeostatic imbalance in muscles to the appropriate term: Sustained spasm, or tetanic contraction. cramp. The space between the neuron and the muscle is the __________. synaptic cleft. A myofibril (also known as a muscle fibril or sarcostyle) is a basic rod-like organelle of a muscle cell. Skeletal muscles are composed of long, tubular cells known as muscle fibers, and these cells contain many chains of myofibrils. Each myofibril has a diameter of 1–2 micrometres. They are created during embryonic development in a process known as myogenesis.
