Definition
deep in the brain, there are several collections of neurons basically involved in motor activity |
|
|
Term
|
Definition
laterally to the thalamus, deep in the brain close the the walls of the lateral ventricles |
|
|
Term
| what does the BG include? |
|
Definition
caudate nucleus (tail like), lenticular nucleus (putamen and globus pallidus b/c they look like a lens), and sustancial nigra (at level of midbrain) we also include subthalamic nucleus below thalamus |
|
|
Term
| globus pallidus is sometimes divided into.. |
|
Definition
|
|
Term
| what is also included as part of the BG? |
|
Definition
| the subthalamic nucleus (below the thalamus) |
|
|
Term
| damage in subthalamic nucleus results in... |
|
Definition
| motor disturbances (in specific types) |
|
|
Term
| what is b/t the 2 thalamus? |

Definition
|
|
Term
|
Definition
| interconnecting lateral ventricles and 3rd ventricle |
|
|
Term
| what is most external and internal? |
|
Definition
external - putamen internal - globus pallidus |

Definition
|
|
Term
| the caudate nucleus tale extends to? |
|
Definition
| amygdala (amygdaloid body) |
|
|
Term
| where is the caudate nuclues situated? |
|
Definition
| at the wall of the lateral ventricles |
|
|
Term
|
Definition
| the caudate nucleus and putamen together |
|
|
Term
| BG is involved in motor control... |
|
Definition
| and interconnected with these cortical areas in frontal lobe involved in motor activity |
|
|
Term
|
Definition
caudate and putamen interconnect w/ sustancial nigra and also interconnect w/ globus pallidus and globus pallidus interconnects to cortex thru thalamus and also interconnects to subthalamic nucleus |
|
|
Term
|
Definition
| another area, besides BG, in the brain that is also involved in motor activity |
|
|
Term
| 3 major systems involved in motor activity |
|
Definition
pyramida system - cortical system basal ganglia cerebellum
|
|
|
Term
| 3 major sytems are subdivided into 2 |
|
Definition
pyramidal system (cortical system) extrapyramidal system (non pyramidal) - basal ganglia and cerebellum
but they are all interconnected and work in a coordinated way |
