Put these structures in the order in which a sensory signal

Put these structures in the order in which a sensory signal might pass, Cervical plexus, dorsal root ganglion, posterior gray horn, receptor, sensory area of brain , spinal nerve C 2, ventral Ramos

Solution

The correct route of the structures through which a sensory signal might pass can be written as:

Receptor - spinal nerve C2 - dorsal root ganglion - Cervial plexus-sensory area of brain - Posterior gray horn - ventral ramos

Explanation: As a stimulus is applied on an area or lower limbs, the receptors present on the surface of cells get excited. These receptors transmit the information of touch/sensation to the brain via the spinal nerves originating from the spinal cord. These nerves accumulate and communicate at the cervial plexus of the brain and transmit the information via dorsal root ganglion which carries afferent neurons. This information is transmitted to the sensory area of brain from where a response is generated. This response is traversed via the posterior or later-end of the gray horn of spinal cord via the efferent neurons to the area of execution of function through the ventral or executional rami.
