Question

Identify the FOUR medial pathways (gross motor and postural movements), identify where each pathway starts (where in the brain or brainstem), where it travels through including if it decussate, where it terminates (in the spinal cord), and what is the primary movement or activation).

Answer 1

Answer:

Corticospinal tracts, Red spinal tract, Cepospinal tract and Vestibulo-spinal tracts.

Explanation:

The corticospinal tracts originate in the cell bodies of

neurons in the cerebral cortex (present in the lobe

front). This pathway is responsible for controlling movements of an involuntary character present in the limbs, specifically in the distal regions of the limbs.

The red-spinal tract originates in the midbrain and is responsible for toning the flexor muscles.

The spinal roof tract originates from the superior coliculus of the midbrain and is responsible for controlling neck movements that have a reflex function in relation to visual stimuli.

The vestibulo-spinal tracts originate in the vestibular nuclei and are responsible for the movement of the eyes and head.
