Question

Sensory fibers containing pain and temperature information ascend or descend 1 - 2 spinal segments in Lissauer's tract before synapsing in the dorsal horn with a 2nd-order neuron, also known as the posterolateral tract. True or False?

Answer 1

The statement is True. Sensory fibers containing pain and temperature information do ascend or descend 1 - 2 spinal segments in Lissauer's tract before synapsing in the dorsal horn with a 2nd-order neuron, also known as the posterolateral tract.

Step-by-step explanation:

The statement is True. Sensory fibers containing pain and temperature information do ascend or descend 1 - 2 spinal segments in Lissauer's tract before synapsing in the dorsal horn with a 2nd-order neuron, also known as the posterolateral tract. This pathway is part of the spinothalamic tract, which is responsible for transmitting pain and temperature sensations from the body to the brain.
