**🎧 NEET PG Neuro QuickPod: Spinothalamic Tract Essentials**
_"Welcome back, future doctors! In today’s brain-hugging episode, we’re diving into a super high-yield topic—Spinothalamic tracts. This is one of those core neuro pathways that pops up across PYQs and is a must-know for NEET PG MCQs. So let’s break it down, mnemonic-style and clinically sharp!"_
🧠 **Segment 1: Quick Anatomy Refresher**
- The spinothalamic tract carries **pain, temperature, crude touch, and pressure** sensations.
- It consists of two parts: **anterior spinothalamic tract (touch & pressure)** and **lateral spinothalamic tract (pain & temperature)**.
- Originates from dorsal horn neurons → crosses to the opposite side at the spinal level → ascends to the thalamus → projects to somatosensory cortex.
📌 **NEET PG Alert: MCQ Trap Watch**
- **Lesion localization**: A right-sided spinal cord lesion affects the **left-sided pain/temp** due to decussation.
- Common question: _"Loss of pain and temperature on left below T10. Where’s the lesion?"_
🧪 **PYQ Highlights**
- NEET PG 2022: Asked about loss of pain/temp below lesion level—correct answer involved lateral spinothalamic tract.
- NEET PG 2019: Image-based MCQ—match sensory pathway with lost modality.
🧬 **Clinical Correlations**
- Conditions like **syringomyelia** (central canal cyst) first affect spinothalamic tract fibers → leads to dissociated sensory loss.
- A favorite examiner trick: showing bilateral loss of pain/temp in a cape-like distribution.
💡 **Mnemonic Corner**
_"Pain and Temp cross early, touch and pressure take their time."_
Think: **'Lateral Love Pain'** (Lateral spinothalamic = pain/temp), **‘Anterior Affection Touch’** (Anterior = touch/pressure).
✅ **MCQ Strategy**
- Track decussation points.
- Don’t mix up dorsal column vs spinothalamic pathways (watch for distractors).
- Look for patterns of sensory loss vs motor loss.
_"That’s all for today’s neuro nugget. Remember, repetition is the key—and now you’re spinothalamic-savvy! Keep smashing those MCQs and we’ll catch you in the next mini-review!"_
