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.
Summary. â¢ Each skeletal muscle cell is individually stimulated by a motor neuron. â¢ The neuromuscular junction is the place where the terminal portion of a motor neuron axon meets a muscle cell membrane, separated by a synaptic cleft.â¢ An action potential arriving at the axon terminal brings about the release of acetylcholine, which leads to depolarization of the motor end plate.age 1. Introduction. â¢ Motor neurons stimulate muscle cells to contract at the neuromuscular junction. Page 2. Goals. â¢ To examine the structure of a neuromuscular junction. â¢ To understand the sequence of events occurring at the neuromuscular junction following a stimulus. Page 3.
