The basal ganglia is involved in initiating movement and inhibiting unnecessary motor outputs from reaching the other parts of the motor system. In parkinsons the substantia nigra of the basal ganglia is destroyed, allowing these extra motor inputs through, hence the jerky, constant movements.
The cerebellum co-ordinates all muscle movements so that fluid movements can take place. If you need to pick up a pen, your cerebellum will co-ordinate all the movements of all the muscles involved so that they happen at the correct amount and time, and in the correct sequence.
Your cerebellum also controls anti-gravity muscles, which are responsible for maintaining correct balance and posture, which they do without concious input.

Is the cerebellum and basal nuclei involved in regulating motor activity and coordinating postural movements?
Yes, both the cerebellum and basal nuclei are involved in regulating motor activity and coordinating postural movements. The cerebellum helps in smooth coordination and precision of movements, while the basal nuclei assist in initiating and inhibiting movements to maintain posture and balance. Together, they play crucial roles in controlling voluntary movements and maintaining stability.
Complex motor activities are controlled by?
a combination of different brain regions and neural pathways. These activities involve coordination of multiple muscles and require the integration of sensory information. The primary motor cortex, cerebellum, and basal ganglia play key roles in planning, executing, and refining complex motor movements. Additionally, sensory areas, such as the somatosensory cortex, provide feedback to help monitor and adjust movements.
What is the nuclei deep within the cerebral hemisphere white matter are collectively?
basal ganglia
Why are basal metabolic measurements important?
Basal metabolic measurements are important because they provide valuable information about the minimum amount of energy your body needs to perform basic functions at rest. This information is useful for determining daily calorie needs, developing personalized nutrition and exercise plans, and monitoring metabolic health. Understanding your basal metabolic rate can help you achieve and maintain a healthy weight.
What is the medial nuclei of the thalamus?
The medial nuclei of the thalamus are a group of nuclei located in the middle part of the thalamus. They play a role in processing emotions, motivation, and memory. These nuclei are involved in relaying information to and from the limbic system and the prefrontal cortex.
What parts of the brain ultimately plan and coordinate complex motor activities?
cerebellum and basal nuclei
Is the cerebellum and basal nuclei involved in regulating motor activity and coordinating postural movements?
Yes, both the cerebellum and basal nuclei are involved in regulating motor activity and coordinating postural movements. The cerebellum helps in smooth coordination and precision of movements, while the basal nuclei assist in initiating and inhibiting movements to maintain posture and balance. Together, they play crucial roles in controlling voluntary movements and maintaining stability.
What passes corrective signals from cerebellum and basal nuclei to motor cortex for control of movement?
Neurons pass information back and forth via electrical and chemical signals.
What leniform nucleus alon with the caudate nuclei are collectively?
The lentiform nucleus along with the caudate nuclei are collectively known as the basal ganglia. The basal ganglia is located deep inside the cerebral cortex and controls some motor functions.
What is nuclei deep within the cerebral hemisphere white matter are collectively called?
The nuclei deep within the cerebral hemisphere white matter are collectively called basal ganglia. These structures are involved in many motor functions and play a role in various cognitive functions as well.
Unwanted muscle contractions are inhibited by what?
The Basal Nuclei or the Basal Ganglia
What does the forebrain structure that works with the cerebellum to coordinate balance?
basal ganglia
Where the basal nuclei of the brain is located?
In your head
What is the function of the basal nuclei?
The basal nuclei are involved in the planning and execution of movement, as well as in some aspects of cognition and emotion. They help regulate muscle tone, coordinate movements, and inhibit unwanted movements. Dysfunction of the basal nuclei can result in movement disorders such as Parkinson's disease.
Where is the motor cortex in the brain?
The motor cortex is located in the brain's frontal lobe, specifically in the precentral gyrus. It is responsible for planning, control, and execution of voluntary movements in the body.
What is a basal ganglion?
A basal ganglion is any of a group of nuclei in the brain interconnected with the cerebral cortex, the thalamus and the brainstem.
Is the basal nuclei part of the major division of the brain?
yes
