Example Question #31 : Help With Brain Physiology
What relationship does the basal nuclei have with movement?
Coordination and muscle memory
Initiation
No relationship with movement
Regulation
Regulation
The basal nuclei is located deep in the cerebral hemisphere and midbrain. It functions with the thalamus to regulate motor signals (regulation only, it does not initiate movement). The basal nuclei encourages wanted and appropriate movement signals and filters out unwanted signals. The caudate nucleus and putamen make up the striatum, and this along with globus pallidus make up the basal nuclei.
Example Question #32 : Help With Brain Physiology
Which of the following layers of the meninges is the innermost layer that lines the cerebral cortex?
Subarachnoid mater
Arachnoid mater
Dura mater
Pia mater
Pia mater
The meninges are responsible for protecting the brain and spinal cord. The tough dura mater is the outermost layer of the meninges, while the pia mater is the delicate inner layer that lines the brain and spinal cord.
In order from the outermost to innermost layer, the meninges are: dura mater, arachnoid mater, subarachnoid space, and pia mater. The arachnoid mater and subarachnoid space create separation and cushioning between the dura mater and pia mater.
