1.2motor And sensory system Flashcards
List the classification of movement
Simples reflex
Posture
Locomotion
Sensory orientation
Action patterns
Acquired skills
What is responsible for the control of movement
Motor cortex
What is the name given to pathways that run outside the pyramidal tract
Extrapyramidal system
List 4 spinal motor pathways
[tracts]
Pyramidal tract
Tectospinal tract
Vestibulospinal tract
Reticulospinal tract
Role of pyramidal tract
Control most of fine movement
Role of tectospinal tract
Head and eye movements
Role of vestibulospinal tract
Postural muscles + balance
Reticulospinal tract
Medial - facilitate movement
Lateral - inhibit movement
List 3 motor control system in the cortex
Primary motor cortex
Supplementary motor cortex
Premotor cortex
Role of primary motor cortex
Source of pyramidal tract neurone
Role of supplementary motor cortex
Conception + initiation of movement
What happens if there’s a lesion in the supplementary motor cortex
Deficit in voluntary movement + speech
Role of premotor cortex
Motor coordination
What happens if there’s a lesion in the premotor cortex
Impair stability stance + hand coordination
List 2 motor control systems outside the cortex
Cerebellum
Basal ganglia
The states of hierarchical processing
