Which of the following correctly lists the structures through which tactile stimuli travels after being converted into neural signals? A. spinal cord, somatosensory cortex, thalamus B. somatosensory cortex, thalamus, spinal cord C. thalamus, spinal cord, somatosensory cortex D. spinal cord, thalamus, somatosensory cortex

Respuesta :

The correct answer is C. Thalamus, spinal cord, somatosensory cortex.

After being converted to neural signals, tactile stimuli travels to thalamus, spinal cord, and somatosensory cortex.

Somatosensory system is being termed as the part in the sensory nervous system. It is also aa complex system which has pathways and sensory neurons which bring changes in the body.

In somatosensory system there are also somatic senses which are also called somesthetic senses.

Answer:

Option C, thalamus, spinal cord, somatosensory cortex

Explanation:

Tactile stimulis are generated  at the surface of the skin.  These are external stimuli and not internal ones.  The sensory receptors in the skin are responsible for converting tactile stimuli into neural signals which are then carried by the sensory nerves to the spinal cord.  

These stimuli are relayed from the thalamus to the somatosensory cortex (in the parietal lobe) via spinal cord and in this way a brain determines the location of touch.  

Hence, option C is correct
