General overview Ascending tracts Sensory Descending tracts Motor General arrangement of both tracts 1st order neuron 2nd order neuron 3rd order neuron The only difference is the different locations where each order of neuron ends. Decussation is the cross-over of the tract from one side to the other. Therefore, there are instances where the left…

✨Spinothalamic Tract: The Pain & Temperature Highway 🛣️ 🚘 The spinothalamic tract is a key sensory pathway in the spinal cord responsible for transmitting pain, temperature, and crude touch sensations to the brain. It consists of two main parts: 🔹 Lateral spinothalamic tract – Carries pain and temperature sensations. 🔹 Anterior spinothalamic tract – Transmits crude touch and pressure sensations. 📌The pathway involves three neurons: 1️⃣ First-order neuron: Detects stimuli and sends…

Spinal cord and associated tracts
Legs (lumbosacral) are lateral in lateral corticospinal, spinothalamic tracts.
Dorsal columns are organized as you are, with hands at sides. “Arms outside, legs inside.”
