Nervous system test

What is the role of the nervous system?

The nervous system activates muscle fibres for contraction to occur

Referring to the sliding filament theory, what do the 'Z-lines' represent?

In the sliding filament theory, actin binds onto myosin to 'grab and pull' the perform a concentric muscle contraction

Referring to the sliding filament theory, myosin binds to actin to perform muscle contractions both eccentrically, concentrically and isometrically

A motor unit is made up of a single motor neuron and further branches of neurons

The all or nothing law refers to the activation of an entire muscle

Select all that apply to the following question: What are the neurological adaptations to resistance training?

Select all that apply to the following question: What are the neurological adaptations to resistance training?

When a signal is sent through the motor unit that breaches the stimulation threshold, only some of the attached muscle fibres are activated
