The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of which tracts
Gemiola [76]

The medial pathway, which controls gross movements of the head, trunk, and limbs, consists of tectospinal, reticulospinal and vestibulospinal tracts.

The tectospinal tract in humans, also known as colliculospinal tract, is a nerve tract that coordinates head and eye movements. This tract is a part of the extrapyrimidal system in which it particularly connects the midbrain tectim and cervical regions of the spinal cord.

The vestibulospinal tract is a neural tract found in the central nervous system. It is specifically also a component of the extrapyramidal system and is a classified component of the medial pathway. The vestibulospinal fibers of the tract relay information from the nuclei to the motor neurons which is the same with the other descending motor pathways.

Lastly, the reticulospinal tracts or the descending or anterior reticulospinal tracts are extrapyrimidal motor tracts that goes down from the reticular formation in two tracts to act on the motor neurons supplying the trunk and the flexors and extensors of the proximal limb.
