Pyramidal Descending Motor Pathway

Motor impulses at the cortical level
Corticospinal and corticobulbar tract
Controls speech movements, which are discrete and skilled movements
Works at a conscious level - voluntary movements
Direct Pathway - this is because its axons descend without synapsing from the pyramidal neurones to the spinal cord
Large neurons with long axons that project into the spinal cord
Control the precise or skilled voluntary movements of our skeletal muscles
If damaged:
Leads to weakness and slowness of movements
Further info:
the pyramidal cells that control foot movements are in one place and those that control hand movements are in another
