Lecture: Motor Control

To outline the anatomical course of the corticospinal tract from the motor cortex to the anterior horn cells.
To describe the roles of the primary motor cortex , premotor and supplementary motor area in the planning and execution of voluntary movement.
To outline the normal control of muscle tone via the stretch reflex.
To understand that lesions of the corticospinal tract will result in upper motor neurone signs (with increased muscle tone/spasticity, brick reflexes and extensor plantar responses).
To describe the roles of the basal ganglia in the initiation of voluntary movements.
To explain that lesions of the basal ganglia result in hypokinetic or kyperkinetic movement disorders.
To outline the roles or the cerebellum in the execution of voluntary movement.
To outline the roles of the cerebellum in the execution of voluntary movement.
To describe the pattern of symptoms and clinical signs found in lesions of the cerebellum.

What are the 3 primary systems involved with motor control?
Briefly overview the pathway of the corticospinal (pyramidal) system.
Describe the anatomy and physiology of the primary motor cortex (brodmann area 4)
Describe the anatomy and physiology of the supplementary motor area and premotor cortex (brodmann area 6)
Describe the anatomy and physiology of the posterior parietal cortex (brodmann area 6)
Describe the anatomy of the descending corticospinal tract
How is muscle tone controlled?
What is an upper motor neurone vs lower motor neurone?
What is spasticity and its physiology?
