Higher Motor Centres Responsibilities

Question 1

Which HMC releases command sequences for locomotor activities - ie - is the primary issuer of command packages related to movement?

Answer 1

MOTOR CORTEX

Question 2

Answer 2

MOTOR CORTEX

Question 3

Name the primary HMC for voluntary (intentional) movement (“think, then do”)?

Answer 3

MOTOR CORTEX

Question 4

Name the primary HMC for dexterity and fine motor control?

Answer 4

MOTOR CORTEX

Question 5

What is the key HMC for functions that combine cognitive and fine motor functions, such as speech?

Answer 5

MOTOR CORTEX

Question 6

Which HMC plays a larger role when movements are complex, skillful, bilateral?

Answer 6

MOTOR CORTEX

Question 7

Because it is constantly generating output, which HMC contributes a significant amount of baseline motor system tone?

Answer 7

MOTOR CORTEX

Question 8

What is the primary HMC for overall coordination, integration of elements within movement command packages?

Answer 8

CEREBELLUM

Question 9

Which HMC monitors incoming sensory information from external and internal body sources (especially visual and proprioceptive data) and integrates this information into organizing effective, appropriate movements?

Answer 9

CEREBELLUM

Question 10

Name the key HMC for body’s motor adjustments to the horizon and to gravity?

Answer 10

CEREBELLUM

Question 11

What is the primary HMC for sequencing/ordering of commands - crucial to perfect movement, especially rapid, complex actions (SSS: speed, sequencing, synchronicity)?

Answer 11

CEREBELLUM

Question 12

Which HMC plays a role in learning - helps mobilize motor command ‘packages’ for newly leaned or improved activities into and out of memory storage?

Answer 12

CEREBELLUM

Question 13

Which HMC performs constant fine tuning of motor commands - monitors motor cortex output, and makes adjustments both while the commands are being issued and after?

Answer 13

CEREBELLUM

Question 14

Which HMC suppresses tremors during purposeful body part activity - through counteracting surge like qualities of motor cortex output?
