Pyramid Path Front

In this article we will look at the pyramidal tract, which is one of the most important elements of the central nervous system. The pyramidal tracts are pathways between the cerebral cortex and the spinal nerves responsible for regulating muscle movement. They allow the brain to control the muscles of the body and control their movements.

The pyramid that you saw in the description should be considered as a brain structure that ensures the transmission of motor impulses from the motor cortex to the spinal cord, controlling muscle contractions. However, there are several types of pyramid paths. Depending on which nerve pool has formed a connection with the descending fibers, the vestibuloopic branch (innervates the palpebral vault), the olivopyramidal tract (provides innervation of the abducens nerve), the rubropalamidal tract (responsible for the coordination of movements), the uterodorsal tract (mastoid-petrilis) are distinguished. and etc.

As a rule, the following neurons take part in the formation of the pyramidal tract:

1. Corticospinal neuron (lower motor neuron). These are cells of the nucleus of the motor cortex of the brain (usually the inferior central gyrus) and are large multipolar neurons that form
