What is the all or nothing principle
When a motor unit fires all muscles affected will contract
Resting membrane potential
The difference between the electric potential on either side of the membrane cell
What is a motor unit
A single motor neurone and the muscle fibre it supplies
Electric impulse passing from node to node
Saltatory conduction
NMJ
Presynaptic axon terminals
Synaptic cleft
Synaptic gutter
Motor endplate
Fatigue
The inability to maintain the required power output to continue muscle work at a given intensity
Levels of fatigue
Peripheral
Central
Thermoregulation
Cellular effects of smoking
Carbon monoxide(CO) forms carb oxyhemoglobin (HbCO)
Main chemicals in tobacco
Nicotine
Tar
Carbon monoxide (CO) turns into (HbCO)
Effects of hyper tension
Left ventricle hypertrophy
Raised pressure in cerebral arteries
Raised blood pressure aggravates atherosclerotic changes in arteries
