Barcelona is the only club to play in each champion league each year, no other club has done it , since it started in 1950. But they have won only three champion league cups. â¦   Fc Barcelona has won the champions league 3 times! Making the world better, one answer at a time.
Define the terms skeletal muscle fiber, motor unit, skeletal muscle twitch, electrical stimulus, and latent period. Skeletal muscle fibers are the individual cells that are bound together in fascicles. Many fascicles are bound together to make a muscle. A motor unit consists of a motor neuron and all of the muscle fibers in innervates. A skeletal muscle twitch is a mechanical response to a single action potential. During this experiment, we used an electrical stimulus to mimic the contractions of skeletal muscles. It is done in vitro to produce in vivo results.
Neuromuscular Junction Skeletal muscle cells contract as a result of impulses from motor neurons. The place where a motor neuron stimulates a muscle cell is called a neuromuscular junction. In order for skeletal muscle cells to contract each cell must be stimulated by a process of a motor neuron.Sliding Filament Theory The theory of how muscle contracts is the sliding filament theory.The contraction of a muscle occurs as the thin filament slide past the thick filaments.n skeletal muscle, the cells never contract individually. Rather they contract as groups of muscle cells that are collectively connected to a motor nerve originating in the spinal cord. The combination of the motor nerve cell (neuron) and the muscle cells it innervates is known as the motor unit.
