Cortical control of motor activity Flashcards
1
Q
What are the cortical areas involved directly in motor control?
A
- prefrontal cortex
- posterior parietal cortex
- supplementary motor cortex
- premotor cortex
- frontal eye fields
- motor cortex
2
Q
What does the premotor cortex do?
A
For sensory guidance of movements and postural adjustments
3
Q
What does the supplementary motor cortex do?
A
For planning spontaneous and bimanual movements
4
Q
What area is the premotor cortex found?
A
Lateral area 6
5
Q
What area is the supplementary motor cortex found?
A
Area 6
6
Q
What are the principal outputs of the motor cortex?
A
- Corticospinal tract
- Corticostriate (caudate and putamen)
- Corticobulbar (pons, cranial nerve nuclei, colliculus, reticular formatin, red nucleus)
7
Q
Principal inputs to the motor cortex?
A
- Supplementary motor area
- Premotor and somatosensory cortex
- Ventral anterior and ventral lateral thalamus (from cerebellum and basal ganglia)
8
Q
What area is the primary motor cortex found in?
A
area 4
