All sensory pathways to the cerebral cortex synapse at the

Answer 1

Hint: Sensory pathways are those which conduct information to the conscious cortex of the brain from sense organs. All the sensations like well-localized touch, light touch, pain, temperature, and vibration through the sensory neuron. This synapse occurs within several segments i.e. pons.

Step by step answer:All sensory pathways to the cerebral cortex synapse at the pons. A pathway over which sensory impulses are conveyed from sense organs or receptors to sensory or reflex centers of the spinal cord or brain. The ascending sensory systems consist of three distinct pathways: the anterolateral system (ALS), the dorsal column medial lemniscal (DCML) pathway, and the somatosensory pathways to the cerebellum. Information is delivered into the spinal cord through the axon terminals of sensory neurons. Once in the spinal cord, the information may flow to motor neurons, to interneurons that pass it directly to the motor neurons, or to interneurons that transmit information to the brain.
Additional information:
Sensory pathways include only those routes which conduct information to the conscious cortex of the
brain. However, we will use the term in its more loosely and commonly applied context to include input
from all receptors, whether their signals reach the conscious level or not. Pain and temperature information from general somatic receptors is conducted over small-diameter (type A-delta and type C) GSA fibers of the spinal nerves into the posterior horn of the spinal cord gray matter. These are unipolar neurons with cell bodies in the posterior root ganglia. After entering the cord, the fibers pass up or down in the dorsolateral tract, located between the tip of the laminae III and IV.

Note: There are many ascending somatosensory pathways including synapses in either the thalamus or the reticular formation before they reach the cortex. Other ascending pathways, particularly those involved with control of posture, are projected to the cerebellum, including the ventral and dorsal
spinocerebellar tracts.
