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.

Which tract is the only lateral tract among the four discussed in the video?

• Reticulospinal tract

• Vestibulospinal tract

• Tecto spinal tract

• Rubrospinal tract

Where does the rubrospinal tract originate?

• Inferior colliculus

• Red nucleus

• Cerebellum

• Superior colliculus

What is the primary function of the rubrospinal tract?

• Control of leg muscles

• Coordination of eye movements

• Regulation of balance

• Control of fine hand movements

How does the rubrospinal tract exert control over skeletal muscles?

• Contralateral control

• Ipsilateral control

• Bilateral control

• Unilateral control

Which tract is known for its lateral position in the spinal cord?

• Vestibulospinal tract

• Tecto spinal tract

• Rubrospinal tract

• Reticulospinal tract

What is the origin of the tecto spinal tract?

• Red nucleus

• Superior colliculus

• Inferior colliculus

• Cerebellum

What is the primary function of the tecto spinal tract?

• Directing head and eye movements

• Coordinating hand movements

• Regulating balance

• Controlling leg muscles
