Document Summary

Celia had seizures and found out reason was tumour in brain: allowed them to film during operation watch. Motor neurons (fusy motor neuron) means higher conduction: innervation ratio is highly dependent on targeted muscle in the eye you may have 1:2 connection (very small) because eyes need precise control (less ratio more control, basic unit of force production. Innervation: distribution of nerves to a part of the body; connectivity of nerves: innvervation ratio: number of muscle fibres (extrafusal) innervated by an alphamotor neuron, extrafusal muscle fibre: power of producing part of your skeletomusclar system. Alphamotor neurons are found: als: neurodegenerative disease with no known cause or cure/treatment, organized in a bodily framework, affects upper/lower motor neurons. Innervate fast twitch muscle fibres contract very quickly: can only work for a short period of time and with a lot of force, fast twitch fatigue resistant: have medium axon width; lower conduction velocity (60 m/s)
