Packets that originate from the brain stem

Packets that originate from the brain stem:

 
Descend to the spinal cord where nerve cells related called cells moderation.
There are four main packages can be divided into two groups:
Packages forehand humanism vetro-medial
Background packages dorso-lateral side

Packages forehand humanism vetro-medial: consisting of:
vestibulo-spinal tracts: receiving information from a balance and is responsible for the balance movements. Therefore, the most important muscle which is connected movement extensors muscles.
tecto-spinal tract: responsible for regulation between the movements of the eyes and the rest of the body.
reticulo-spinal tracts: in particular responsible for the movements of the extensor muscle reflexes.
All of these packages ending at motor region that gives orders to the trunk and muscles sides near the trunk.


Background packages side dorso-lateral:
rubro-bulbar tracts
rubro-spinal tracts
Responsible for the movements of the flexor muscles flexors

 

Brain stem:
Important in organizing movements. Any link between sensations and movements.
It works as a bridge between advanced thinking in the top (of the brain) and the spinal cord.
