The Neuromuscular System Flashcards
What are the three main types of muscle fibre?
> Slow oxidative type
fast oxidative gylcolytic type
fast glycolytic type
Define motor neurones
Nerve cells which transmit the brain’s instructions as electrical impulses to the muscles.
What is the role of the parasympathetic and sympathetic systems in the context of the autonomic nervous system and neuromuscular system
> The sympathetic nervous system prepares the body for exercise and is often referred to as the flight or fight response
The parasympathetic nervous system has the opposite effect of the sympathetic system and relaxes the body and slows down many high energy functions. It is often explained by the phrase rest and relax
Define hypertrophy
where the muscle has become bigger and stronger
What does aerobic and anaerobic mean
exercising with oxygen, low to medium intensity and without oxygen, high intensity
Describe wave summation
Where there is a repeated nerve impulse with no time to relax so a smooth, sustained contraction occurs, rather than twitches
Describe spatial summation
When the strength of a contraction changes by altering the number and size of the muscle’s motor units
Describe PNF (proprioceptive neuromuscular facilitation)
It is an advanced stretching technique.It is also constructed to be one of the most effective
