Somatic Motor System

Question 1

What are the two Types of Movement?

Answer 1

Reflexive and Voluntary
Voluntary also has subcategory of Rhythmic (they look reflexive but are voluntary)

Question 2

What is the Feedforward Control Mechanism

Answer 2

Anticipatory Control/ Planning in Advance

Question 3

What is Feedback Control?

Answer 3

Monitoring movement and comparing desired movement with actual movement (error correction)
Uses sensory info to make adjustments after movement

Question 4

What are the 4 Subsystems that control functional movement?

Answer 4

Dorsolateral, Ventromedial, Corticonuclear, and Visual Motor

Question 5

What tracts are contained in Dorsolateral system?

Answer 5

Lateral Corticospinal and Rubrospinal Tract

Question 6

What tracts are located in Ventromedial System?

Answer 6

Anterior Corticospinal, Reticulospinal, and vestibulospinal tracts

Question 7

What is serial Processing?

Answer 7

A pathway goes from one place to another and then to another (one after other)

Question 8

What is Parallel processing?

Answer 8

When all tracts work together to produce coordinated movement

Question 9

How does Motor System transform goals into appropriate actions?

Answer 9

Requires:
- Motor Plan
- Execution
- Monitoring
