21) Motor Cortex Flashcards
1
Q
Define the motor cortex, where is it located?
A
- Area of the cortex implicated in planning the movement
- Located on the pre-central gyrus known as M1 / Brodmann area 4 on the frontal lobe
2
Q
List the systems involved in motivation
A
- Sensory systems
- Limbic areas
- Reticular areas
3
Q
List the systems involved in planning
A
- Basal ganglia
- SMA = supplementary motor area
- PFC = prefrontal cortex
4
Q
List the systems involved in programming
A
- PPC = posterior parietal cortex
- PMC = premotor cortex
- MCx = motor cortex
5
Q
What is the function of the cortex?
A
- Converting intention/motivation to controlled muscle activity via signals that regulate:
- Programme of action
- Sequence
- Duration
- Force
6
Q
List the systems involved in integration
A
- Cerebellum
- Brainstem
7
Q
List the systems involved in execution
A
- Spinal column
- Muscles
8
Q
What is the function of the cerebellum ?
A
- Integration (along with brainstem)
- Regulate / adjust movements by comparing intended and actual movement
9
Q
What is the function of the brainstem?
A
- Integration (along with cerebellum)
- Regulate / adjust movements by comparing intended and actual movement
10
Q
What is the function of the sensory systems?
A
- Motivation
- Alongside limbic and reticular areas
11
Q
What is the function of the limbic and reticular areas?
A
- Motivation (alongside sensory systems)
12
Q
What is the function of the basal ganglia?
A
- Planning (alongside supplementary motor area and prefrontal cortex)
13
Q
What is the function of the supplementary motor area?
A
- Planning
- alongside prefrontal cortex and basal ganglia
14
Q
What is the function of the posterior parietal cortex?
A
- Programming
- Alongside premotor cortex and motor cortex
15
Q
What is the function of the premotor cortex?
A
- Programming
- Alongside posterior parietal cortex and motor cortex
