Question

The dorsal column–medial lemniscal pathway and the spinothalamic (anterolateral) pathway are significantly different. In which ways are the two pathways similar? Group of answer choices Their fibers conduct action potentials at the same rate Both pathways synapse deep in the dorsal horn of the spinal cord

Answer 1

Both pathways synapse deep in the dorsal horn of the spinal cord.

Step-by-step explanation:

Spinothalamic: The first neuron is in the spinal node. The central prolongation of this neuron penetrates the medulla and synapts with the second-order neurons located in the posterior horn of the spinal cord.

Dorsal column-medial lemnisccal: The axons of the first order neurons located in the spinal ganglion, penetrate the medulla and ascend forming part of the posterior cords of the same side. In the bulbar nuclei (gracillis and cunneatus) they synapt with the second neuron.
