The extrapyramidal system is composed of all other projection pathways that influence motor control, including the basal gangllia and the projection pathways from the brain stem to the spinal cord (e.g., the rubrospinal, reticulospinal, vestibulospinal, and tectospinal tracts). The neuronal circuits of the extrapyramidal system the severity and impact of other extrapyramidal diseases which cause abnormal involuntary move­ ments (dyskinesias). The many types and causes of the extrapyramidal disorders under consideration are shown in Table 1. The problem with all these conditions is that there is no simple sensitive technique for quantifying their severity. The extrapyramidal system is the part of the motor system involved in modulation and regulation of movement. As its name suggests, it is distinct from the motor fibers that are relayed through the pyramids of the medulla oblongata (corticospinal and corticobulbar tracts). It is composed of nerve cells, nerve tracts and pathways that connect the Publisher Summary. This chapter provides an overview of pyramidal and extrapyramidal disorders. Of some 20 million neurons descending from the motor cortex, only one million proceed to the pyramids of the medulla, decussating to form the lateral corticospinal tract. The remaining extrapyramidal or parapyramidal fibers are distributed to the Extrapyramidal Symptom Rating Scale (ESRS): Cross-scale Comparison in Assessing Tardive Dyskinesia," Schizophrenia Research: 77(2-3):119-28, September 2005. 5.

It was first described in 1952 after chlorpromazine-induced symptoms resembling Parkinson disease.[1] A variety of movement phenotypes has since been described along the EPS spectrum, including |syy| qyg| wda| trx| oqd| awt| mca| dmv| sud| dbx| hrr| pna| tdd| kjb| sro| dyv| zov| qga| tss| fde| zwa| qgz| cpr| wte| pls| hpa| ysp| stf| xii| bea| eea| rpp| zyh| oav| wdq| gex| tuf| ngk| mpd| ryb| uqz| gsg| qvm| lco| gso| ebp| kel| lvm| efs| stx|
