Starting with a Meissner’s corpuscle in the index finger (digit2) trace the afferent pathway to the brain and then the efferentpathway to the flexor digitorum profundus muscle that enervates theflexion of the index finger. For the afferent pathway be sure todescribe the peripheral afferent nerves and the spinal nerve plexusinvolved. Then describe the three afferent systems, theanterolateral system (ALS), the dorsal column-medial lemniscalpathway (DCML), and the somatosensory pathway to the cerebellum ofthe spinal cord. Which pathway carries the fine touch sensoryinformation from Meissner’s corpuscles up the spinal cord? What isthe major afferent processing center in the diencephalon? What isthe final destination of the fine touch sensory information in thecerebral cortex? Is this fine touch sensation conscious orunconscious sensation? How does the brain respond to generate amotor or efferent response? For the efferent pathway start with theprimary motor cortex in the precentral gyrus. For the efferentpathways be sure to describe the pyramidal and extrapyramidalefferent pathways. Which is involved in fine motor control? Whatplexus and arm nerve is involved in this motor control of theflexor digitorum profundus muscle? What role does the cerebellumplay in the flexion or the index finger?
