Major subdivisions of the central nervous system - Sequential movement and supplementary motor area

4 important questions on Major subdivisions of the central nervous system - Sequential movement and supplementary motor area

The supplementary motor area (SMA) (area 6) is crucial for?

Generating movements in the absence of explicit sensory cues,

How does the SMA neurons convey information

It is more active as it wants to guide the production of a sequence of reaching movements

What role does the prefrontal cortex play of movement sequeces

The initiation and termination of movement sequences

What does the primary motor cortex for sequences of commands

They activate pools of motor units in the brainstem and spinal cord to produces the desired movements

The question on the page originate from the summary of the following study material:

  • A unique study and practice tool
