Document Summary

And on the left side if we want to strengthen/extend that leg, the opposite is going to happen here as did in the right leg. So the interneurone releases the positive/excitatory neurotransmitter to the motor neurones that connect to the extensor muscle causing them to release the neurotransmitter there hence causing that muscle to contract, this is going to strengthen the left knee. Chemical signals (endocrine system second control system: neurotransmitters are a type of chemical signal that involved in the nervous system. Endocrine system typically doesn"t involve neurotransmitters, however there is cross-talk between the two systems. Type of local regulators: secreting cell a ects itself, paracrine signalling cell a ecting/turning other cells on. In this type of signalling, a cell releases a signal in the interstitial uid where it interacts with nearby cells. The cells that don"t have the right receptor for the signal released by the cell do nothing, but those that do respond accordingly.
