What are the extrapyramidal pathways?

What are the extrapyramidal pathways?

The four main pathways that connect the aforementioned structures are the reticulospinal, vestibulospinal, rubrospinal and tectospinal tracts. This article will discuss the anatomy and function of the extrapyramidal system.

What does pyramidal mean in neurology?

upper motor neurons
The term pyramidal tracts refers to upper motor neurons that originate in the cerebral cortex and terminate in the spinal cord (corticospinal) or brainstem (corticobulbar).

What are pyramidal signs and symptoms?

Pyramidal signs indicate that the pyramidal tract is affected in some region. Pyramidal tract dysfunction can lead to clinical presentations like spasticity, weakness, slowing of rapid alternating movements, hyperreflexia, and Babinski sign.

Is the extrapyramidal pathway part of the medullary pyramid?

They are often referred to as fasciculi (bundles) or lemnisci (ribbons). The extrapyramidal pathway or system is an important part of the motor system of the body and can also be described as the descending motor pathway, whose fibres pass through the tegmentum rather than the medullary pyramid.

How is the extrapyramidal system involved in voluntary movements?

The extrapyramidal system is actively involved in the initiation and selective activation of voluntary movements, along with their coordination. This system also regulates the involuntary movements (reflexes), as opposed to the pyramidal system which controls the voluntary movements only.

Where are pyramidal tracts located in the brain?
