Q

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

A

MOTOR CORTEX

2
Q

Which HMC is the key higher motor centre in learning of new motor activities through visual observation (“see and reproduce”) or as part of a process of thought/imagination (invention)?

A

MOTOR CORTEX

3
Q

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

A

MOTOR CORTEX

4
Q

Name the primary HMC for dexterity and fine motor control?

A

MOTOR CORTEX

5
Q

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

A

MOTOR CORTEX

6
Q

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

A

MOTOR CORTEX

7
Q

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

A

MOTOR CORTEX

8
Q

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

A

CEREBELLUM

9
Q

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?

A

CEREBELLUM

10
Q

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

A

CEREBELLUM

11
Q

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

A

CEREBELLUM

12
Q

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

A

CEREBELLUM

13
Q

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?

A

CEREBELLUM

14
Q

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

A

CEREBELLUM

15
Q

Which HMC is the first initiato - ‘alerts’ the other centres to the need for new command sequences to be issued.

A

BASAL GANGLIA
aka
BASAL NUCLEI

16
Q

Name the key HMC in oversight of reflexive relationships in the motor system?

A

BASAL GANGLIA
aka
BASAL NUCLEI

17
Q

Name the HMC which performs error correction?

A

BASAL GANGLIA
aka
BASAL NUCLEI

18
Q

Which HMC adds gracefulness and efficiency to movement?

A

BASAL GANGLIA
aka
BASAL NUCLEI

19
Q

Which HMC suppresses tremors in body parts NOT engaged in purposeful activity, through counteracting surge like qualities?

A

BASAL GANGLIA
aka
BASAL NUCLEI

20

A

CEREBELLUM
+
BASAL GANGLIA
