The medial reticulospinal tract (pontine) is responsible for exciting anti-gravity, extensor muscles. The fibers of this tract arise from the caudal pontine reticular nucleus and the oral pontine reticular nucleus and project to lamina VII and lamina VIII of the spinal cord.
The medial pathway helps control gross movements of the proximal limbs and trunk. The lateral pathway helps control precise movement of the distal portion of limbs. [1] The vestibulospinal tract, as well as tectospinal and reticulospinal tracts are examples of components of the medial pathway. [1]
The medial lemniscus, also known as Reil's band or Reil's ribbon (for German anatomist Johann Christian Reil), is a large ascending bundle of heavily myelinated axons that decussate in the brainstem, specifically in the medulla oblongata. The medial lemniscus is formed by the crossings of the internal arcuate fibers.

medial dorsal nucleus of thalamus nucleus raphe magnus and gigantocellular raphe nucleus → raphespinal tract → spinal trigeminal nucleus and posterior grey column of the spinal cord - the fibers of the tract terminate by forming excitatory serotonergic synapses with inhibitory enkephalinergic interneurons which in turn form inhibitory ...
reticulospinal tract: connects the reticular system, a diffuse region of gray matter in the brain stem, to the spinal cord. It also contributes to muscle tone and influences autonomic functions. It also contributes to muscle tone and influences autonomic functions.
Medial inferior pontine syndrome is a condition associated with a contralateral hemiplegia. [ citation needed ] "Medial inferior pontine syndrome" has been described as equivalent to Foville's syndrome .
The medial part of the vestibulospinal tract is the smaller part, and is primarily made of fibers from the medial vestibular nucleus. It projects bilaterally down the spinal cord and triggers the ventral horn of the cervical spinal circuits, particularly controlling lower motor neurons associated with the spinal accessory nerve (CN XI).
