The Neuromuscular Junction And Muscle Stimulation. Skeletal Muscle Fibers. A muscle fiber is a multinucleated muscle cell that attaches to connective tissue. Sarcolemma is the muscle cell membrane. Sarcoplasm is the cytoplasm containing nuclei, mitochondria, and myofibrils.

And Muscle Stimulation
Motor neuron axons join the skeletal muscle at the neuromuscular junction.
A motor unit consists of the motor neuron and the muscle fibers it controls.
It is generated by phosphokinase when there is excess ATP.
What causes this?
What are the stimuli for hypertrophy?
(energy balance, protein)
(testosterone, insulin, growth hormone)
(active training, passive stretch)
There is huge individual variation in hypertrophy response to training.
Did you wonder if it was real or not?
