Spinothalamic Tracts – Simplify by PharmaWhisper
The spinothalamic tracts are part of the ascending sensory pathways in
the spinal cord that carry information from the body to the thalamus in
the brain.
Types of Spinothalamic Tracts:
1. Lateral Spinothalamic Tract
2. ➤ Carries:
a. Pain
b. Temperature
3. Anterior (Ventral) Spinothalamic Tract
➤ Carries:
a. Crude touch
b. Pressure
Pathway (General):
1. First-order neuron
a. From skin → enters spinal cord via dorsal root
b. Synapses in dorsal horn
2. Second-order neuron
a. Crosses to opposite side (decussates) in the spinal cord
b. Ascends to the thalamus
