Document Summary

Sensorimotor arc: between the input of sensory information and the output of motor commands, there is neural integration. This integration occurs for the actions of re exes and for the voluntary actions. We will start with the re exes since their mechanisms are simple and very well-known: then we will speak in general terms about neural integration for voluntary actions because their mechanisms are far more complex and much less understood. Basic reflex arc: a re ex is an automatic action triggered by a stimulus, the action can be a movement, salivation, an increase in heart rate or others. The stimulus can be mechanical, visual, auditory or others: the re exes are classi ed 2 ways. According to the control of the re ex involuntary re ex learned or conditioned re ex. Normally, the re ex for protection and balance have priority over the control of voluntary movements.
