Spinocerebellar Pathways Explained | Dorsal, Ventral & Cuneocerebellar Tracts

For more cadaveric images and question banks, visit https://bootcamp.com/med-school The spinocerebellar system integrates sensory input for automatic balance, posture, and movement coordination. In this video, we explore the dorsal, ventral, and cuneocerebellar pathways, their neuron chains, peduncle entry points, and decussation patterns. Clinical correlations highlight why dorsal/cuneocerebellar lesions cause ipsilateral deficits, while the ventral tract may produce contralateral signs depending on lesion location. Essential for neurology and spinal cord lesion localization. What you’ll learn: 1. Dorsal spinocerebellar tract – Clarke’s column, ipsilateral pathway, inferior cerebellar peduncle 2. Ventral spinocerebellar tract – double decussation, superior cerebellar peduncle, contralateral vs ipsilateral lesions 3. Cuneocerebellar tract – accessory cuneate nucleus, upper limb proprioception 4. Dermatome coverage – C1–C7 (cuneocerebellar), C8–L3 (dorsal), L4–Co1 (ventral) 5. Clinical correlations – lesion localization (ipsilateral vs contralateral deficits) By the end, you’ll understand how the dorsal, ventral, and cuneocerebellar tracts integrate proprioceptive input and how to predict lesion effects based on their decussation patterns. ⏱️ Timestamps 0:00 – Intro 0:07 – Overview of spinocerebellar pathways 0:23 – Function: unconscious proprioception 1:00 – Example of proprioceptive awareness (hand behind back) 1:23 – Dermatomes & body organization 1:50 – Cuneocerebellar tract – C1–C7, upper limbs, head & neck 2:30 – Dorsal spinocerebellar tract – C8–L3, trunk & lower limbs 2:56 – Ventral spinocerebellar tract – L4–Co1, anterior & posterior lower limbs 3:26 – Comparison: dorsal vs ventral tracts location 3:56 – Dorsal spinocerebellar pathway step by step 4:29 – Ipsilateral projection via inferior cerebellar peduncle 4:56 – Lesion effects in dorsal spinocerebellar pathway 5:24 – Ventral spinocerebellar tract pathway explained 6:01 – Superior cerebellar peduncle entry & double decussation 6:24 – Lesion effects: contralateral vs ipsilateral deficits 7:31 – Cuneocerebellar tract pathway explained 7:57 – Accessory cuneate nucleus → inferior cerebellar peduncle 8:29 – Ipsilateral projection of cuneocerebellar tract 9:05 – Summary of dorsal, ventral & cuneocerebellar pathways 10:09 – Clinical key point: lesion localization (ipsilateral vs contralateral) 10:30 – Wrap-up & conclusion This lesson is especially helpful for medical students, or anyone reviewing for anatomy exams.
