(2) - Answer-- change in transmitter size - change in ...

_____ bring a cell to threshold while _____ bring a cell further from threshold - ️️EPSPs; IPSPs Describe the mechanism of fusimotor drive - ️️muscle spindles are parallel to extrafusal fibres; the extrafusal fibres shorten when they contract, and the gamamotorneuron causes the intrafusal fibres to contract in order to maintain tension in the centre of the muscle spindle so it is still able to detect muscle stretch thoughout the entire ROM What things determine the type of cell tha...
