motor unit types Flashcards
what are the 3 motor unit types?
1) slow twitch aerobic1 2) fast twitch 2a 3) fast twitch x
what is the source of fuel for 1) aerobic 2) anerobic ?
fats/triglycerides 2) glycolytic and glycogen and 3)glycogen and cp
Identifying muscle fibers. what fiber stains dark in an acid?
Preincubation acid ph./4 is type 1
Identifying muscle fibers. Myosin atphase ph above 10?
type 2x stains dark with a basic solution and opp for type 1
what fiber stains dark blue with sdh?
oxidative/type 1
A single motor neuron is defined by size?
No, its defined by 3 characteristics that influence the amount of fibers (size is not one) innervated 1) accuracy 1) precision and 3) coordination of movement for a task
what are the 2 types of physiology?
1) applied physiology
2)fundamental physiology
what is fundamental physiology?
1)Fundamental physiology the “basics” physiology. Its about the understanding the basic principles and mechanisms of how the body functions at a cellular, molecular, and organ system level.
2) is the research side of physiology. The hunt to understand bodily functions more
what is applied physiology?
It is the hands on and the application of fundamental physiology for example Appling the understanding how muscles get bigger through external loads. athletic performance. It uses knowledge to address specific outcomes such as enhancing performance in a practical way.
examples of applied vs fundamental phys?
Fundamental (understanding)
cellular physiology
energy metabolism
muscle hypotrophy
mitochondria function
Applied( application of knowledge)
aerobic sports
hilt training
neural physiology
muscle physiology
all in relation to exercise or sport
the clinical acute chronic responses
