system consisting of nerve cells, nerve tracts, and pathways that connects the cerebral cortex, basal ganglia, thalamus, cerebellum, reticular formation, and spinal neurons that is concerned with the regulation of reflex movements such as balance and walking.
One of the two cerebral motor control systems; it is older in evolutionary terms, and it controls relatively gross movements of the head, limbs, and trunk.
Refers to central nervous system structures (i.e., outside the cerebrospinal pyramidal tracts) that play a role in controlling motor functions. The extrapyramidal system includes substructures of the basal ganglia and the brainstem and interconnections with certain regions of the cerebellum, cerebrum, and other areas of the central nervous system. Extrapyramidal disturbances may result in postural and muscle tone abnormalities as well as the development of certain involuntary movements.
the system of nerve cells, nerve tracts and pathways that connects the cerebral cortex, basal ganglia, thalamus, cerebellum, reticular formation, and spinal neurons. It is responsible for the regulation of reflex movements such as balance and walking. The extrapyramidal system is damaged in Parkinson's disease.
That part of the nervous system that regulates subconscious control of skeletal muscle through the basal ganglia. Symptoms that result from impairment of this system include, but are not limited to, weakness, abnormal muscle reflexes, and increased muscle tone. close window
The nerve cells, nerve tracts and pathways that connect the cerebral cortex, basal ganglia, thalamus, cerebellum, reticular formation, and spinal neurons. The EPS helps regulate reflex movements such as balance and walking.
The part of the central nervous system that connects the cerebral cortex, basal ganglia, thalamus, cerebellum, reticular formation and spinal neurones. The extrapyramidal system controls muscle tone, posture and stereotyped movements (for example, walking) and is damaged in PD
a motor system of the brain that indirectly controls muscle movements
In human anatomy, the extrapyramidal system is a neural network located in the brain that is part of the motor system involved in the coordination of movement. Extrapyramidal neurons, like related gamma system neurons, excite or inhibit anterior horn cells. The extrapyramidal system is primarily regulated by the nigrostriatal pathway.
