Description[edit | edit source]
The Reticulospinal tract is responsible primarily for locomotion and postural control. The Reticulospinal tract is comprised of the medial (pontine) tract and the lateral (medullary) tract. [1]
Anatomy[edit | edit source]
Origin[edit | edit source]
- Reticular formation in the pontine (Medial Reticulospinal tract) and medulla (Lateral Reticulospinal tract) [2]
[edit | edit source]
Course / Path[edit | edit source]
Medial Reticulospinal Tract (Pontine)[edit | edit source]
- Descend ipsilaterally in the anterior funiculus.
Lateral Reticulospinal tracts(Medullary)[edit | edit source]
- Descend bilaterally in the lateral funiculus.
Both the lateral and medial tracts act via internuncials shared with the corticospinal tract on proximal limb and axial muscle motor neurons[1]
Function[edit | edit source]
- Control activity of both alpha and gamma motor neurones. [2]
- Mediate pressor and depressor effects on the circulatory system. [2]
- Help to control breathing [2]0
Medial Reticulospinal Tract (Pontine)[edit | edit source]
- Responsible for controlling extensor motor neurons
Lateral Reticulospinal Tract (Medullary)[edit | edit source]
- Responsible for flexor motor neurons.
Locomotion
Posture
The reticular formation within the pons is partly responsible for postural control functions.
Pathology[edit | edit source]
Leisons to the cortico-reticulospinal system can result in decreased postural control and reduced selectivity of postural conrol. [3]
