Other Motor Tracts [Part 2] | Rubrospinal & Tectospinal Tracts

The video tutorial discusses motor pathways from the brain to skeletal muscles, focusing on the rubrospinal and tectospinal tracts. The rubrospinal tract, originating from the red nucleus, controls fine hand movements and distal extensor muscles, exerting contralateral control. The tectospinal tract, originating from the superior colliculus, uses visual stimuli to direct head and eye movements towards stimuli. Both tracts decussate in the midbrain before reaching the pons.

What are the main functions of the rubrospinal tract?

Describe the origin and pathway of the rubrospinal tract.

What is the significance of decussation in the rubrospinal and tecto spinal tracts?

Discuss the differences between the rubrospinal tract and the lateral corticospinal tract.

What types of movements are associated with the rubrospinal tract?

Explain the role of the superior colliculus in the function of the tecto spinal tract.

How does the tecto spinal tract utilize visual stimuli?
